Growth characteristics and ascorbic acid content of several genotypes of jute (Corchorus olitorius Linn)

Abstract: Starchy staple foods of the tropical countries are usually eaten with leafy vegetables, such as jute. It is grown in Africa, the Caribbean, and tropical Asia for the preparation of draw-soup (Grubben, 1977; Purseglove, 1972). There is considerable diversity among accessions, with varying leaf shapes being important differentiating characteristics between cultivars (Akoroda, 1985). If a visible cultivar characteristic could be associated with edible leaf yield and ascorbic acid (AA) content, it could act as an indicator for identifying cultivars with the desirable qualities. We describe characteristics of some Nigerian jute cultivars and attempted to associate some visible properties with yield potential and AA concentration and determine the appropriate time of harvest to optimize AA content. Seedlots of eight accessions of jute were separately steeped in hot water (100C) for 10 sec to break dormancy. The seeds were airdried and sown 2 cm deep in an open field.

Allelopathic effects of jute (Corchorus capsularis and C. olitorius) and sisal (Agave sisalana) leaf leachates on rice (Oryza sativa), wheat (Triticum aestivum)

Abstract: A study was conducted during 2007 to screen leaf leachates of jute (Corchorus capsularis L. and C. olitorius L.) and sisal (Agave sisalana Perrine) for allelochemicals effect on germination and seedling growth of some test plants. A rice (Oryza sativa L.), wheat (Triticum aestivum L. emeond. Fiori & Paol.) and (greengram [Vigna radiata (L.) R. wilczek] allelochemicals present in the leachates inhibited differentially the germination and growth of the plants. Effect of allelochemicals on germination of the plants was less pronounced as compared to that on seedling growth. Highest inhibition on germination (paddy seeds by about 28% over control) and seedling vigour (about 48 – 62% vigour loss over the control) in the plants was recorded in case of Capsularis jute leaf extracts. Among the test plants, seedling growth of wheat was affected most by the leachates. Similar effect on germination and seedling growth of plants was also recorded when leaf samples were incorporated into soil (1: 10, w/w).

Effects of Methanol Extract of Corchorus olitorius Cultivated in Iraq on High Fat Diet plus Streptozotocin-induced Type II Diabetes in Rats

Abstract: Background: Diabetes mellitus (DM) is a long-lasting clinical syndrome characterized by raised blood glucose leading to numerous other complications. Objective: To study the phytochemical, anti-hyperglycemic, anti-hyperlipidimic and histopathological effects of methanol extract of Corchorus olitorius cultivated in Iraq against induced type II diabetes in rats. Methods: C. olitorius leaves extracted with 60% methanol then phytochemical analysis done, forty male rats separated into four groups ten in each the first not received any treatment as a normal control, remaining rats were induced diabetes type 2 by 28 days feeding of high fat diet followed by single intraperitoneal injection of streptozotocin 35 mg/kg, ten of them not received treatment served as diabetics, third and fourth groups received oral metformin (MET) 100 mg/kg and C. olitorius methanol extract (COME) 400 mg/kg respectively for 28 days. Blood samples collected at day 29 for biochemical study of lipid profile and glycemic indices as well as assessment of histological effects on pancreatic tissue sections after scarification. Results: C. olitorius methanol extract contains anthraquinons, flavonoids, saponines and steroids. Treatment with MET or COME significantly reduced the elevated levels of fasting blood glucose, glycated hemoglobin A1, homeostasis model assessment of insulin resistance, total cholesterol, triglycerides, low density lipoprotein and very low density lipoprotein, while, enhance the reduced levels of adiponectin and high density lipoprotein, also COME enhanced insulin release. Histopathological picture of pancreatic tissues of COME or MET treated rats improved than diabetics. Conclusion: Methanol extract of C. olitorius cultivated in Iraq has anti-hyperglycemic, insulin releasing and sensitizing, anti-hyperlipidimic and pancreatic tissue protective effects in type 2 diabetic (T2D) rats.
