三丫苦的化学成分研究(Ⅱ)

Chemical constituents in the roots of Evodia lepta(Spreng.) Merr(Ⅱ)

采用硅胶柱色谱法从三丫苦的乙酸乙酯萃取物中分离得到4种化合物,经波谱分析鉴定为:(1)香草木宁,(2)(trans)-3,4,5-三羟基-6-乙酰基-7-甲氧基-2,2-二甲基色烷,(3)茵芋碱,(4)(trans)-3,4-二羟基-5-甲氧基-6-乙酰基-7-甲氧基-2,2-二甲基色烷,它们均为首次从该植物的根部分离得到.

Silica gel column chromatography was used to isolate four known compounds from the ethyl acetate extracts of the roots of Evodia lepta（Spreng.）Merr,which were identified by spectral methods as（1）kokusaginine,（2）（trans）-3,4,5-trihydroxy-6-acetyl-7-methoxy-2,2-dimethylchroman,（3）skimmianine and（4）（trans）-3,4-dihydroxy-5-methoxy-6-acetyl-7-methoxy-2,2-dimethylchroman.All these compounds were isolated from the roots of Evodia lepta（Spreng.） Merr for the first time.
