Calathea leopardina nutrient fluid

Abstract: The invention discloses velvet maranta nutrient fluid, which relates to the field of plant nutrient fluid. The velvet maranta nutrient fluid comprises the following compositions according to the proportion (mg/L): 590 to 945 mg/L of Ca(NO3) 2, 253 to 809 mg/L of KNO3, 68 to 153 mg/L of KH2PO4, 347 to 493 mg/L of MgSO4 and microelements (mg/L): 20 mg/L of Na2Fe-EDTA, 2.86 mg/L of H3BO3, 2.13 mg/L of MnSO4.4H2O, 0.22 of ZnSO4.7H2O, 0.08 of CuSO4.5H2O and 0.02 of (NH4)6Mo7O24.4H2O. After a formula of the nutrient fluid is used, the survival rate of transplanting seedlings of velvet maranta is improved from 84 percent to 99.3 percent; and the capacity for resisting diseases is stronger and the growing speed is higher.

O gênero Maranta L. (Marantaceae) no estado de Pernambuco, nordeste do Brasil

Abstract: Eight species are described from genus Maranta L. (Marantaceae) from State of Pernambuco, Northeastern Brazil. Maranta anderssoniana and Maranta hatschbac hiana (Marantaceae) are described as a new species to science. Illustrations and their relationships between other species of Marantaceae are briefly discussed. Notes about geographic distributions and ecological aspects are pointed too. M. anderssonian a distinguished from the others specially by the zingiberoid growth habit and green color leaves; M. hatschbachiana by rosulate habit and thickened rhizome. The same treatment with a key for identification is present for M. arundinacea L., M. bicolo r Ker Gawl, M. divaricata Rosc., M. leuconeura Morren, M. protracta Miq. e M. zingiberi na L. Anderss. They are also registrated for humid forest of Pernambuco.

Antibacterial activity of selenium nanoparticles synthesized using Maranta arundinaecea root extract

Abstract: Maranta arundinaecea is otherwise known as arrowroot. It promotes weight loss, treats diahorrea and stimulates the immune system. As Arrowroot is rich in starch, it helps in good digestion by mild laxative in regulating the bowel movement. Also it reduces stomach pain and bloating. Selenium is a semi conductor so it is used in making electrical wires. It is used in potent chemotherapy. It is an anti-cancer agent due to its invasion of apoptotic pathway and cell cycle arrest. Usually the arrow root extract is available as powder. The powder is diluted and mixed into sodium selenite solution and this combination is observed for 3 days. After 3 days, it is centrifuged and collected in a pellet form. The lactobacillus and streptococcus mutants are used for culture of organism for 1 day. The extract is tested for for anti-bacterial activity. Result- It shows the sector where it can inhibit in Streptococcus mutans and lactobacillus. Maranta arundinaecea root mediated selenium nanoparticles shows very good antibacterial activity will used in many biomedical applications is future.

Maranta (Maranta arundinacea L) Starch Properties

Abstract: Maranta (Maranta arundinacea L) can be considered as a non-conventional raw material for starch. Thus, the objective of this work was the characterization of the Maranta starch. These starch granules had spherical and elongated geometries with average size of 56.6μm. The Maranta starch presented B-type crystal, revealed by x-ray spectra, and gelatinization temperature of 65.5°C, determined by DSC analysis. Maranta starch suspensions have a pseudoplastic behavior which was well described using a power law model. And, storage and loss moduli increased drastically during gelatinization process, corroborating with DSC results. In general, maranta starch could have numerous food industrial applications.

Proximate composition, glycemic indices, and some factors affecting glycemic indices of underutilized tubers

Abstract: The present study was conducted to determine the proximate composition, glycemic indices (GIs), and some physicochemical properties of starch of boiled tubers of Dioscorea alata (violet and white), Maranta arundinacea, and Canna indica with the intention of recommending these for consumption or utilization as an ingredient in food preparation. Proximate compositions of cooked tubers were determined according to standard methods. GIs were determined according to FAO/WHO guidelines with bread as the standard. The size and shape of the starch granules and the carbohydrate molecular size distribution were studied to correlate their effects to individual GIs. Digestible carbohydrate ranged from 59.0 to 69.1 g/100 g dry weight (DW) and was not significantly (p > 0.05) different among the tubers. Crude protein content ranged from 4.5 to 9.2 g/100 g DW with Dioscorea (violet) and Maranta having the highest amounts, 9.2 and 8.6%, respectively. Fat contents were low (1.2–2.3 g/100 g DW). The contribution by insoluble and soluble fiber ranged from 7.0 to 11.0 and 4.0 to 6.0 g/100 g DW, respectively. Dioscorea tubers (violet and white) were categorized as low GI, with corresponding GI's of (±SEM) 64 ± 9 and 69 ± 4, respectively. Maranta was categorized as a medium GI (82 ± 8) and Canna as a high GI (110 ± 8) food. Microscopic studies and carbohydrate distribution patterns indicated cell enclosed starch granules in the two Dioscorea varieties, which have not been reported earlier. It is concluded that, low GI yams (Dioscorea white and violet) have a high potential to be utilized as a functional ingredient in food formulations targeting individuals who require glycemic control.
