Abstract:
The dichloromethane fraction obtained from the methanolic extract of leaves of P. lhotzkyanum afforded a C-glucosylflavone (kaplanin) together with sakuranetin, methyl 4-methoxydihydroferulate and a mixture of methyl ferulate and dihydroferulate derivatives. Spectrometric methods were used to elucidate the structures of these compounds.
