西双版纳产砂仁根、根茎及茎的化学成分研究

Studies on Chemical Constituents of Roots,Rhizomes and STems of Amomum villosum Lour

从西双版纳产砂仁根及根茎中分离鉴定了二十八碳酸乙酯，己酸二十二碳酯，新化合物豆甾－４－烯－１，３－二酮，β－谷甾醇和胡萝卜甙。从茎中分离鉴定了胡萝卜甙和大黄素葡萄糖甙。均为首次报道。

thyl octacosate,docosyl hexylate,a new compound stigmast-4-ene-1,3-dione,β-sitosterol and daucosterol wereisolated and identified from the rcots and rhizomes of Amomum villosum cultivated in Xishuangbanna,Yunnan. Twocompounds daucosterol and emodin monoglycocide were isolated and ident ified from the stems of A. villosum.
