ABSTRACTSix subfractions (H2O eluted fraction, 20% ethanol eluted fraction, 40% ethanol eluted fraction, 60% ethanol eluted fraction, 80% ethanol eluted fraction and acetone fraction) of a 95% ethanol extract of Phyllostachys pubescens leaves were sequentially partitioned by column chromatography (macroporous absorption resin). For the first time, nine specific major flavonoids were isolated from...
