绿茎还阳参化学成分的研究

Chemical Constituents of Crepis lignea

采用柱层析和重结晶从药用植物绿茎还阳参(Crepis lignea)丙酮提取物中分离得到7个单体化合物,并根据化合物的理化性质和波谱分析,分别鉴定为:3β-acetoxyurs-13(18)-ene(1),lupeol acetate(2),4-hydroxy-3-methoxycinnamaldehyde(3),(Z)-2-ethylidene-3-methylsuccinic acid(4),olean-12-ene-11α-methoxy-3β-acetate(5),α-amyrin acetate(6)和lupeol-9(11)en-3β-acetate(7)。上述化合物均为首次从绿茎还阳参中分离得到。

Seven compounds were isolated from the acetone extract of the medicinal plant Crepis lignea by column chromatography and recrystallization.Their structures were mainly identified by their spectral and physical data as 3β-acetoxyurs-13（18）-ene（1）,lupeol acetate（2）,4-hydroxy-3-methoxycinnamaldehyde（3）,（Z）-2-ethylidene-3-methylsuccinic acid（4）,olean-12-ene-11α-methoxy-3β-acetate（5）,α-amyrin acetate（6） and lupeol-9（11）en-3β-acetate（7） respectively.All compounds were obtained from Crepis lignea for the first time.
