Identification and stereochemical characterization of lignans in flaxseed and pumpkin seeds.

Abstract: Phytoestrogens of the lignan type are widely distributed in plant-derived food items and are believed to protect against hormone-dependent cancer. The richest known dietary source of lignans is flaxseed. Flaxseed has been reported to contain glycosides of secoisolariciresinol as the major lignan, together with small amounts of matairesinol, isolariciresinol, and pinoresinol. Secoisolariciresinol, but none of the other lignans, has so far been identified in pumpkin seeds. In the present study, two different methods for the hydrolysis of lignan glycosides are compared. Artifact formation and loss of lignans under acidic conditions were observed. Lariciresinol was identified by GC-MS analysis in two different types of flaxseed (Linum usitatissimum L. and Linum flavum L.) and in pumpkin seeds (Cucurbita pepo L.) for the first time. Likewise, the novel lignan demethoxy-secoisolariciresinol was tentatively identified in the flaxseed samples. Stereochemical analysis by chiral HPLC of several lignans isolated from flaxseed showed that secoisolariciresinol, matairesinol, and lariciresinol consisted predominantly of one enantiomer.

Quantification of the ratio of positional isomer dilinoleoyl‐oleoyl glycerols in vegetable oils

Abstract: The distribution of fatty acids in a triacylglycerol is of great importance from nutritional, biochemical, quality and technological points of view. The ratio of triacylglycerol positional isomers containing two linoleic acid (18:2) and one oleic acid (18:1) moieties--namely, 1(3),2-dilinoleoyl-3(1)-oleoyl glycerol (LLO) and 1,3-dilinoleoyl-2-oleoyl glycerol (LOL)--were quantified in grape seed, olive, pumpkin seed, soybean, sunflower and wheat germ oils by high-performance liquid chromatography/atmospheric pressure chemical ionization mass spectrometry (HPLC/APCI-MS) in selected ion monitoring (SIM) mode. Relative LOL contents (LOL/(LLO+LOL)) of the oils were calculated from the mass abundances of the [LL]+ and [LO]+ diacylglycerol fragment ions ([M+H-RCOOH]+) using a calibration curve. The calibration curve of the relative diacylglycerol mass abundances was measured in SIM mode. The relative LOL contents were found to be relatively consistent for each oil variety. The relative LOL content in grape seed, sunflower, pumpkin seed, soybean and wheat germ oils accounted for 44.2 +/- 2.6, 26.8 +/- 3.2, 16.7 +/- 4.6, 15.9 +/- 2.9 and 13.9 +/- 4.3%, respectively. Only olive oils contained practically 100% of the LLO isomer. These results indicate that the unsaturated fatty acids such as linoleic and oleic acids have 'non-random' distribution patterns in various oils.

Fluorescence screening of antioxidant capacity in pumpkin seed oils and other natural oils

Abstract: Plant oils provide a rich source of dietary polyunsaturated fatty acids (PUFAs) and mostly lipophilic antioxidants. PUFAs are both in their free form and as components of glycerolipids preferred targets of free radical-induced oxidation, leading to the formation of highly atherogenic compounds. Thus, stabilization of polyunsaturated lipids by radical scavengers in the oils is important in order to avoid pathophysiological side effects of these essential components of our diet. To determine lipid oxidizability and its inhibition by endogenous antioxidants, we developed a simple fluorescence technique. It is based on solubilisation of the oils in aqueous buffer, labeling of the resulting emulsions with a suitable reporter fluorophore, which reflects lipid oxidation, and continuous monitoring of the decomposition process. Using this method, we found that oxidizability of the oils depended only to a limited extent on the content of lipophilic antioxidants. In addition, a smaller fraction of polar (phenolic) compounds showed comparable protective effects, especially in pumpkin seed oil, which is a non-refined product therefore containing antioxidative components that are removed from most other edible oils during processing. Therefore, the contribution of these “minor” compounds has to be taken into account when potential biological effects of plant oils are evaluated.

Determination of trace elements in pumpkin seed oils and pumpkin seeds by ICP-AES

Abstract: Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used for the determination of the elements present in pumpkin seed oil and pumpkin seeds. After extraction of the oil from pumpkin seeds a residue was obtained. For the determination of elements three types of samples were used: oil, seeds and the residue (after oil extraction). Three different digestion types were applied: open vessel and closed vessel digestion in a steel bomb as well as microwave digestion in a closed system. For most elements of interest the measured concentration differs depending on the digestion method used. After microwave digestion a good reproducibility for ICP-AES measurements for all elements was found. Determination of Zn by ICP-AES is possible both after open and closed vessel digestion (steel bomb or microwave digestion). No loss of volatile compounds in pumpkin oil during preparation or microwave digestion prior to ICP-AES analysis could be observed. In general, the recoveries for all elements in pumpkin seed oils and seeds were >95%, for S only they were 0.8 µg g−1 for Al, Cr and P in pumpkin oil samples.

Evaluation of the nutritional quality of breads prepared from wheat-fluted pumpkin (Telfairia occidentalis Hook) seed flour blends

Abstract: The effect of blending wheat flour with fluted pumpkin (Telfairia occidentalis Hook) seed flour at levels of 0 to 10% on selected chemical and nutritional properties of composite breads was investigated. Bread loaves were prepared using the straight-dough procedure. Protein quality was evaluated using weanling male albino rats fed composite bread diets which were formulated to supply 10% protein, with casein diet as a control. When wheat flour was replaced with 10% defatted fluted pumpkin seed flour, there was an increase of 80.8% in crude protein, 43.9% in calcium, 71.9% in potassium and 63.0% in phosphorus contents of composite breads. Diets formulated with 5% or 10% fluted pumpkin–substituted breads showed significantly (p < 0.05) higher values for weight gain, protein efficiency ratio, apparent and true digestibilities than diets formulated with 100% wheat flour bread, suggesting an improvement of the nutritional quality of fluted pumpkin–substituted composite breads.

Expression Studies of Gibberellin Oxidases in Developing Pumpkin Seeds 1

Abstract: Two cDNA clones, 3-ox and 2-ox, have been isolated from developing pumpkin (Cucurbita maxima) embryos that show significant amino acid homology to gibberellin (GA) 3-oxidases and 2-oxidases, respectively. Recombinant fusion protein of clone 3-ox converted GA12-aldehyde, GA12 ,G A 15 ,G A 24 ,G A 25, and GA9 to GA14-aldehyde, GA14 ,G A 37 ,G A 36 ,G A 13, and GA4, respectively. Recombinant 2-ox protein oxidized GA9 ,G A 4, and GA1 to GA51 ,G A 34, and GA8, respectively. Previously cloned GA 7-oxidase revealed additional 3-hydroxylation activity of GA12. Transcripts of this gene were identified in endosperm and embryo of the developing seed by quantitative reverse transcriptase-polymerase chain reaction and localized in protoderm, root apical meristem, and quiescent center by in situ hybridization. mRNA of the previously cloned GA 20-oxidase from pumpkin seeds was localized in endosperm and in tissues of protoderm, ground meristem, and cotyledons of the embryo. However, transcripts of the recently cloned GA 20-oxidase from pumpkin seedlings were found all over the embryo, and in tissues of the inner seed coat at the micropylar end. Previously cloned GA 2,3-hydroxylase mRNA molecules were specifically identified in endosperm tissue. Finally, mRNA molecules of the 3-ox and 2-ox genes were found in the embryo only. 3-ox transcripts were localized in tissues of cotyledons, protoderm, and inner cell layers of the root apical meristem, and 2-ox transcripts were found in all tissues of the embryo except the root tips. These results indicate tissue-specific GA-biosynthetic pathways operating within the developing seed.

Microwave-assisted saponification for the determination of 16 polycyclic aromatic hydrocarbons from pumpkin seed oils

Abstract: The production of pumpkin seed oil requires a roasting of the pumpkin seeds, at temperatures generally higher than 60°C. The roasting at elevated temperatures produces the typical taste of the pumpkin seed oil but may also be the source of a contamination with carcinogenic PAHs. Owing to their lipophilic character, their bioaccumulation, and their toxicity these compounds should be subject to mandatory monitoring. Since there is a lack of norms and legal limits for hot-pressed oils, the limits set by the German Society of Fat Science of 25 μg/kg for the sum of 16 PAHs and 5 μg/kg for the heavy fraction for refined and cold-pressed oils, such as olive oil and others, have to be applied. Sample preparation was performed by microwave-assisted saponification with 1.5 M methanolic potassium hydroxide followed by a liquid-liquid extraction and purification with sulfuric acid. A final clean up procedure was performed on activated silica gel combined with a preparative Bondesil-cyano phase. For a selective measurement of the individual analytes, gas chromatography combined with mass spectroscopy was used in single ion monitoring mode. The overall analytical procedure was validated by systematic recovery experiments and by analyzing the certified reference material BCR CRM 458. Finally, this validated method was used for quality control of pumpkin seed oils from a producer co-operative.

Effect of germination on bread-making properties of wheat-fluted pumpkin (Telfairia occidentalis) seed flour blends

Abstract: Rheological and bread-making properties of blends containing 0-25% defatted flours from ungerminated and germinated fluted pumpkin (Telfairia occidentalis Hook) seed substituted wheat flour blends were investigated Dough rheology was studied using a Chopin alveograph, while bread loaves were prepared from the blends using the straight-dough procedure and evaluated for loaf weight, loaf volume, loaf height and sensory characteristics Up to 10% substitution of wheat flour with ungerminated pumpkin flour produced bread with acceptable crust and crumb color and crumb texture Loaf height and volume, however, decreased significantly (p < 005) when the pumpkin flour level in the bread increased beyond 5% Germination had no effect on dough extensibility, hot increased resistance to extension and mechanical work for dough deformation Addition of flour from germinated pumpkin seeds to wheat flour had a detrimental effect on loaf volume, bread color and texture

Study on the hypoglycemic action of pumpkin extract in diabetic rat

Abstract: Objective: To study the hypoglycemic action in diabetic rats by soluble polysaccharides (A), protein components with molecular weights above 60 ku (B),3-60 ku(C) ,and below 3 ku(D) of some pumpkin seeds,arginine(E)and pumpkin seed oil(F). Methods: Ten rats were selected randomly as control ,while the other 150 rats were injected with alloxan 170 mg/kg to induce diabetes.The diabetic rats were divided into 15 groups:the model,A(1000,500 mg/kg),B(300,150 mg/kg),C(300,150 mg/kg),D(300,150 mg/kg),E(100,50 mg/kg),F(300,150 mg/kg),Gilbenclamide(20 mg/kg).The above components were given intragastrically for 10 d and then blood samples were taken to determine serum glucose and insulin, and also to test the glucose tolerance. Results: It was indicated in diabetic rat that the blood insulin level was obviously increased by the soluble polysaccharides , the protein components with molecular weight over 60 ku and below 3 ku after 4 d germination. The blood glucose tolerance was improved by seed oil, protein components with molecular weights 3-60 ku and arginine. Conclusion: The protein components with molecular weights about 3-60 ku have the best hypoglycemic action, in terms of improving the blood glucose tolerance and decreasing the blood glucose level of diabetic rats.

Effects of fermentation on nutrient content and some functional properties of pumpkin seed (Telfaria occidentalis)

Abstract: Nutritional and some functional properties of fermented pumpkin seed (‘Ure ohi’) were examined and compared with the unfermented seed. The results obtained show that unfermented seed contained 3.75%, 28.0%, 48.0%, 4.4%, 2.6% and 13.25% moisture, crude protein, crude fat, mineral ash, crude fiber and carbohydrate, respectively. Corresponding values for ‘Ure ohi’ were 3.5%, 39.4%, 25.5%, 5.6%, 2.4% and 23.6%. Fermentation significantly increased the protein content and decreased the fat content. Unfermented seed had higher values for emulsion capacity and stability, bulk density, foam capacity and stability than those of fermented seed. The ‘Ure ohi’ had better cold water dispersability, and water and oil absorption capacities. Both samples gelled. The results of nutrient analyses indicate that when ‘Ure Ohi’ is used as soup condiment it will contribute to the protein intake of the consumers.

Pressurized wet digestion in open vessels.

Abstract: The High Pressure Asher (HPA-S) was adapted with a Teflon liner for pressurized wet digestion in open vessels. The autoclave was partly filled with water containing 5% (vol/vol) hydrogen peroxide. The digestion vessels dipped partly into the water or were arranged on top of the water by means of a special rack made of titanium or PTFE-coated stainless steel. The HPA-S was closed and pressurized with nitrogen up to 100 bars. The maximum digestion temperature was 250 °C for PFA vessels and 270 °C for quartz vessels. Digestion vessels made of quartz or PFA-Teflon with volumes between 1.5 mL (auto sampler cups) and 50 mL were tested. The maximum sample amount for quartz vessels was 0.5–1.5 g and for PFA vessels 0.2–0.5 g, depending on the material. Higher sample intake may lead to fast reactions with losses of digestion solution. The samples were digested with 5 mL HNO3 or with 2 mL HNO3+6 mL H2O+2 mL H2O2. The total digestion time was 90–120 min and 30 min for cooling down to room temperature. Auto sampler cups made of PFA were used as digestion vessels for GFAAS. Sample material (50 mg) was digested with 0.2 mL HNO3+0.5 mL H2O+0.2 mL H2O2. The analytical data of nine certified reference materials are also within the confidential intervals for volatile elements like mercury, selenium and arsenic. No cross contamination between the digestion vessels could be observed. Due to the high gas pressure, the diffusion rate of volatile species is low and losses of elements by volatilisation could be observed only with diluted nitric acid and vessels with large cross section. In addition, cocoa, walnuts, nicotinic acid, pumpkin seeds, lubrication oil, straw, polyethylene and coal were digested and the TOC values measured. The residual carbon content came to 0.2–10% depending on the sample matrix and amount.

Dancing into the Past: Colonial Legacies in Modern Caddo Indian Ceremony

Abstract: THE BICENTENNIAL OF THE LOUISIANA PURCHASE is an appropriate moment to consider the different ways the peoples of the Louisiana Territory have remembered their history One group of indigenous inhabitants-the Caddo Indians who, at the beginning of the colonial period, occupied a homeland extending across present southwest Arkansas, northwest Louisiana, northeast Texas, and southwest Oklahoma-use a particular ceremony, the Turkey Dance, to recall the past To understand Caddo history within the context of their knowledge system, we might begin with a story of Caddo origins: The original home of the Caddo was on lower Red River in Louisiana According to their own traditions they came up from under the ground through the mouth of a cave in a hill which they call Cha' kani'na, "The place of crying," on a lake close to the south bank of Red river, just at its junction with the Mississippi In those days men and animals were all brothers and all lived together under the ground But at last they discovered the entrance to the cave leading up to the surface of the earth, and so they decided to ascend and come out First an old man climbed up, carrying in one hand fire and a pipe and in the other a drum After him came his wife, with corn and pumpkin seeds Then followed the rest of the people and the animals All intended to come out, but as soon as the wolf had climbed up he closed the hole, and shut up the rest of the people and animals under the ground, where they still remain Those who had come out sat down and cried a long time for their friends below, hence the name of the place Because the Caddo came out of the ground they call it ina, mother, and go back to it when they die Because they have had the pipe and the drum and the corn and pumpkins since they have been a people, they hold fast to these things and have never thrown them away1 The fact that Caddo Indians today hold to this account of their origins suggests that their concepts of history differ from those held by folk in societies descended from western European traditions In the latter case, history is often regarded as a linear, chronological narrative concerning flesh-and-blood personages, real events, and actual circumstances that help us understand the past and its connection with the present For Caddos (and for most other American Indians), history likewise provides an account of how present circumstances developed But the inclusion of their emergence and separation from underground worlds shared with animal kin as part of that history betoken an altogether different perception of reality Belief in return to the earth following passage through life on the earth also suggests this, reflecting the Caddos' eternal as well as chronological time frames At the same time, references to links between emblematic goods and Caddo existence as "a people" suggest a second important function of history, identity formation2 So it is that every society creates history according to its own understandings of the world and of time/space relationships Different groups use history for distinctive purposes The means by which communities maintain their histories are varied too Social structures, political and economic arrangements, ceremonial performances, storytelling, and recognition of special places and emblematic objects all may be used to maintain ties with the past The preservation of historical information in written accounts is important in western or European-derived societies, but such sources are less important or are absent altogether among other groups Many American Indian communities, for example, embed historical knowledge into a variety of "texts," including those spoken, crafted, and danced3 This suggests the need for alternatives to universal definitions of history, ones that understand history in terms of multiple systems of socially constructed "ways of knowing"4 The Caddo Turkey Dance is an excellent example of a non-written historical text …

[Alpha-linolenic acid and cardiovascular diseases].

Abstract: IMPORTANCE AND METABOLISM OF ALPHA-LINOLENIC ACID: Alpha-linolenic acid is an essential fatty acid which cannot be produced in the body and must be taken by food. Both in animals and humans, alpha-linolenic acid is desaturated and elongated into eicosapentaenoic and docosahexaenoic acid. It is also incorporated into plasma and tissue lipids and its conversion is affected by levels of linoleic acid. POTENTIAL ROLE IN PATHOGENESIS OF CARDIOVASCULAR DISEASES: Diet enriched in n-3 fatty acids, especially alpha-linolenic acid, reduces the incidence of cardiac death. Studies have shown that alpha linolenic acid prevents ventricular fibrillation which is the main cause of cardiac death. Studies in rats suggest that alpha-linolenic acid may be more effective in preventing ventricular fibrillations than eicosapentaenoic and docosahexaenoic acid. Furthermore, alpha-linolenic acid is the main fatty acid decreasing platalet aggregation which is an important step in thrombosis i.e. non-fatal myocardial infarction and stroke. DIETARY SOURCES AND NUTRITION RECOMMENDATIONS: Dietary sources include flaxseed and flaxseed oil, canola oil, soybean and soybean oil, pumpkin seed and pumpkin oil, walnuts and walnut oil. Strong evidence supports beneficial effects of alpha-linolenic acid and its dietary sources should be incorporated into balanced diet for prevention of cardiovascular diseases. The recommended daily intake is 2 g with a ratio of 5/1 for linoleic/alpha-linolenic acid.

[Purification and partial characterization of luffin P1, a peptide with translational inhibitory activity and trypsin inhibitory activity, from seeds of Luffa cylindrica].

Abstract: A peptide, luffin P1, from seeds of Luffa cylindrica, was purified by ammonia sulfate precipitation, CM-52 ion exchange chromatography, Blue-gel affinity chromatography and FPLC Mono S ion exchange chromatography. Its molecular weight was 5226.5 as determined by MALDI-TOF-MS analysis. The sequence of N-terminal 11 amino acids of luffin P1 was identical with the partial N-terminal sequence (from G3 to R13) of 6.5K Arg/Glu rich peptide, which was also isolated from the seeds of Luffa cylindrica. Besides, luffin P1 had a very high homology with a trypsin inhibitor, named C2 peptide, from pumpkin seeds. Interestingly, the purified luffin P1 not only showed a strong inhibitory activity on protein synthesis in rabbit reticulocyte lysate cell-free translation system with IC(50) of 0.6 nmol/L, but also had trypsin inhibitory activity with IC(50) of 22 micromol/L.
