Black soybean peptide mixture purified from Rhynchosia volubilis exerts antioxidant activity against H2O2-induced cytotoxicity and improves thrombosis
Oxidative stress has been reported to be associated with cellular injury. Here, we investigated the antioxidant ability of a novel peptide mixture purified from black soybean (Rhynchosia volubilis) that exhibited significant antioxidant ability (IC50 = 119.8 ± 1.2 µg/ml) under in vitro ABTS assay conditions. To confirm this result, we next examined the antioxidant ability of the peptide...

Average stem biomass of Prangos cheilanthifolia as a medicinal plant in Shanjan Rangelands, East Azerbaijan, Iran
Plants can be used for animal grazing, in wind erosion control, to reduce water flow rates, and to increase evaporation and transpiration. In the Northwest (NW) of Iran (East Azerbaijan Province), rangelands previously used to animal grazing were changed to agricultural land use; this vegetation is unsuitable vegetation coverage. We studied Prangos cheilanthifolia to determine its stem biomass characteristics....

Tropane alkaloids of Atropa belladonna L. and Atropa acuminata Royle ex Miers plants
The purpose of the present study was to determine the tropane alkaloid content in different parts of the wild and cultivated Atropa belladonna L. and wild Atropa acuminata Royle ex Miers in Iran. Determination of alkaloids was performed by high-performance liquid chromatography (HPLC) method. Samples were extracted with chloroform- methanol- cc. ammonia 15:15:1(v/v/v). HPLC separation was performed...

Investigation of fermentation conditions and optimization of medium for taxol production from taxol-producing fungi
The monofactor-design test was used to optimize the culture conditions for the fermentation of taxol-producing fungus UV40-19 as follows: the initial pH value of the fermentation broth was 5.5, the culture temperature was 25°C, and the rotational speed was 150 r/min. Orthogonal design was used to optimize the fermentation medium of taxol-producing fungi. The optimized medium increased the yield of taxol to...

Enhancement of diosgenin production in Dioscorea zingiberensis seedling and cell cultures by beauvericin from the endophytic fungus Fusarium redolens Dzf2
Diosgenin production in seedling and cell suspension cultures of Dioscorea zingiberensis C. H. Wright was enhanced by treatment with beauvericin obtained from its endophytic fungusFusarium redolens Dzf2. Optimal elicitation of diosgenin production by beauvericin in D. zingiberensis seedling and cell cultures was achieved when beauvericin was added to the medium at a concentration of 100 mg/L (in...
