isoferulic-acid and myricetin

To study the chemical constituents from Sarcopyramis nepalensis.. Compounds were isolated by D101 macroporous adsorption resin column and purified by repeatedly chromatographic techniques on Sephadex LH-20, silica gel and ODS columnl chromatograph. Their structures were elucidated by chemical and spectral methods.. Six compounds were isolated from Sarcopyramis nepalensis, and identified as kaempferol (1), myricetic (2), dihydroquercetin (3), egllagic acid (4), isoferulic acid (5) and caffeic acid (6).. All compounds are isolated from the genus for the first time.
