      Identification and quantification of withaferin-A in different fractions of Withania coagulans dunal by TLC and HPTLC method
      S. PRASAD*, S. HEMALATHA, T. THITE, M. KRISHNAN (*Dept. of Pharmaceutics, Institute of Technology, Banaras Hindu Univ., Varanasi, U.P., India)

      Abstract No. C-97, 61st IPC (2009). Chromatographic methods are reported for identification (TLC) and quantification (HPTLC) of withaferin-A in methanolic and chloroform extract of dried fruits of Withania coagulans. Chromatographic separation on silica gel with toluene - ethyl acetate - formic acid 5:5:1. The identification of withaferin-A in both chloroform and methanolic extracts was performed by comparison of hRf values and UV absorbance maxima (209 nm). Quantification was performed by absorbance measurement at 540 nm after spraying the developed plate with Liebermann-Burchard reagent. Methanolic extracts and chloroform extracts contained 3.67 mg/g and 2.10 mg/g of withaferin-A, respectively. No withaferin-A was found in hydroalcoholic extracts.
