红花酢浆草地上部分的化学成分研究

Chemical Constituents of the Aerial Part of Oxalis corymbosa DC.

为了解红花酢浆草(Oxalis corymbosa DC.)地上部分的化学成分,从其70%乙醇提取物中分离鉴定了6个化合物,经理化性质和波谱数据分析,分别鉴定为:芫花素(1)、corniculatin A(2)、槲皮素(3)、咖啡酸(4)、肉桂酸(5)、木犀草素-7-O-β-D-葡萄糖苷(6)。所有化合物均为首次从红花酢浆草地上部分分离得到。

In order to understand the chemical constituents of Oxalis corymbosa DC., six compounds were isolated from 70% ethanol extract of the aerial part. On the basis of physicochemical and spectral data, they were identified as： genkwanin（1）, corniculatin A（2）, quercetin（3）, caffeic acid（4）, cinnamic acid（5）, luteolin-7-O-β-D-glucopyranoside（6）. All compounds were isolated from the aerial part for the first time.
