【摘要】 <正> 尼泊尔独活(Heracleum nepalense D.Don.)系伞形科白芷属植物,多分布于滇西北2500公尺上下土质肥沃而潮湿的沟谷、坡地。丽江民间称牛尾独活,用于祛风除湿和外感咳喘。有些地方常将该药与白云花(H.rapula Fr.)混用。该植物的化学成分迄今未见报道。为了弄清它与白云花根化学成分的异同,我们对其根的化学成分进行了研究。更多还原

【Abstract】 The dried roots of Heracleum nepalense D. Don. were extracted with ether, and the extract chromatographed over alumina, afforded four furano-coumarins which were identified as pimpinellin, bergapten, sphodin and isopim-pinellin by mp. IR and NMR spectra. In addition, β-sitosterol was also separated.更多还原
