Abstract

The flavanolignans of the fruits were isolated by column chromatography and identified by TLC and HPLC in addition to m.p., ms, uv and optical rotation measurements. A comparative study by TLC and HPLC of the flavanolignans from the purple flowered and the white-flowered plants of Silybum marianum  was performed. The major flavanolignans of the white flowered plants were identified as silybin, silychristin, silydianin and taxipholin. The major flovanolignans of purple-f lowered plants were found to be silybin, silichristin and taxipholin.
