榕树须活性部位的成分研究

Chemical Constituent of Active Fraction from Radix Aerio Fici microcarpae L.

采用硅胶柱层析色谱和重结晶方法对榕树须95%乙醇提取物进行分离,得到8化合物,通过理化性质和波谱技术分别鉴定为:α-香树脂醇乙酸酯(1),羽扇豆醇乙酸酯(2),木栓酮(3),木栓醇(4),正三十五烷醇(5),白桦酯酸(6),β-谷甾醇(7)和豆甾-4-烯-6β-羟基-3-酮(8)。除化合物6外,其余化合物均为首次从该植物中分离得到。

Eight compounds were isolated from the 95% extract of the traditional Chinese herb Radix Aerio Fici Microcarpae L.by using silica gel column chromatography and recrytallization.On the basis of physicochemical properties and spectroscopic analysis,they were identified as α-amyrin acetate（1）,lupeol acetate（2）,friedelin（3）,friedelinol（4）,1-pentatriacontanol（5）,betulinic acid（6）,β-sitosterol（7）,and tigmast-4-en-6β-ol-3-one（8）,respectively.These compounds were isolated from this plant for the first time with the exception of compound 6.
