丝瓜叶化学成分的研究

STUDIES ON THE CHEMICAL COMPONENTS FKOM LEAVES OF LUFFA CYLINDRICA ROEM

从丝瓜（ＬｕｆｆａｃｙｌｉｎｄｒｉｃａＲｏｅｍ．）叶中分得一种新的五环三萜皂甙和芹菜素，用光谱和化学方法确定该皂甙的结构为２１β－羟基齐墩果酸－２８－Ｏ－β－Ｄ－吡喃葡萄糖贰，命名为丝瓜皂甙Ｑ．

A new pentacyclic triterpenoid saponin,lucyoside Q,has been isolated from theleaves of Luffa cylindrica along with apigenin. Its structure was established as 21β-hydroxyloleanoicacid-28-O-β-D-glucopyranoside based on spectral evidence and chemical methods.
