筒鞘蛇菰的三萜及甾醇成分研究

目的：研究蛇菰科筒鞘蛇菰Balanophora involicrata Hook,f．的化学成分，方法：采用反复硅胶柱层析分离纯化，通过理化常数测定和光变分析鉴定基化学结构，结果，从筒鞘蛇菰的石油醚和乙酸乙酯萃取部分共分得8个化合物，鉴定了其中的6个，即：熊果烷－12烯－11－羰基－3－醇正二十八酸酯 （ursa-12-ene-11-one-3-ol octocosate,I),β－香树酯醇正十六酸酯（β－amyrin hexadecatnte,II),β－香树脂醇（β－amyrin，III），羽扇豆醇（lupeol,IV),β－谷甾醇（β－sitosterol,V)和β－谷甾醇葡萄糖苷（β－sitosterol glucoside,VI)结论：除V外，各化合物均为首次从该植物吩得，其中化合物I为新化合物。

Studies on triterpenoids and steroids from Balanophora involucrata

Object The chemical constituents of Balanophora involucrata Hook.f. (Balanophoraceae) were studied. Methods Individual constituent was isolated and repeatedly purified on silica gel column, identified by physico-chemical constants and structurally elucidated by spectral analysis. Results From the petroleum ether and ethylacetate extracts, 8 compounds were obtained, 6 of them were identified as: ursa-12-ene-11-one-3-ol-octocosate (Ⅰ)，β-amyrin hexadecanate (Ⅱ)，β-amyrin (Ⅲ)，lupeol (Ⅳ)，β-sitosterol (Ⅴ) and β-sitosterol glucoside (Ⅵ). Conclusion All of these compounds, with the exception of Ⅴ, were obtained from this plant for the first time, and compound I was a new one.
