Withania somnifera (L.) Dunal. (Indian ginseng) is an important medicinal plant which yields pharmaceutically active compounds, namely withanolides. This study deals with the optimisation of the adventitious root suspension culture of W. somnifera for the production of biomass and withanolide-A. We investigated the effects of macro elements (NH(4)NO(3),(More)
Polygonum multiflorum Thunb. is a highly important medicinal plant producing anthraquinones (emodin and physcion) and phenolic compounds which has pharmaceutical use. In vitro seedling explants such as roots, internodals, nodals and leaves were inoculated with A. rhizogenes strain KCTC 2703. Transformed roots were induced from internodals and leaf explants.(More)
Momordica charantia is an important vegetable crop and is also used in traditional medicine. The production of secondary metabolites from hairy root cultures of Indian M. charantia (IMC) and Korean M. charantia (KMC) along with their biological activities (antioxidant and antimicrobial activities) were compared. The explants (leaves, cotyledons, hypocotyls,(More)
This work deals with optimisation of adventitious root suspension culture of Withania somnifera (L.) Dunal (Solanaceae) for the production of biomass and withanolide A and we investigated the effect of carbon source and the initial medium pH on growth and production of withanolide A in adventitious root cultures of Withania somnifera. A 2% sucrose(More)
Withania somnifera is an important medicinal plant that contains withanolides as bioactive compounds. We have investigated the effects of macroelements and nitrogen source in hairy roots of W. somnifera with the aim of optimizing the production of biomass and withanolide A content. The effects of the macroelements NH4NO3, KNO3, CaCl2, MgSO4 and KH2PO4 at(More)

Withanolide A is an important secondary metabolite in Withania somnifera, which is having a high medicinal value and possesses potent anti-tumor and antioxidant properties. Distribution of withanolide A in various organs of Withania somnifera was investigated by High Performance Liquid Chromatography (HPLC) method. The quantitative distribution of(More)
Phenolic contents and antioxidant capacities from different solvent extracts (petroleum ether, ethyl acetate, methanol, butanol and water) of Aster scaber leaf were investigated. Antioxidant activity was evaluated by three different methods, namely DPPH radical scavenging activity, reducing power assay and phosphomolybdenum activity. A total of twenty-three(More)
