广东紫珠的化学成分

Chemical constituents from Callicarpa kwangtungensis Chun

马鞭草科紫珠属植物广东紫珠（Callicarpa kwangtungensis Chun）地上部位的水提取物经多种色谱方法进行分离纯化，运用波谱学方法鉴定了9个化合物，分别为pinnatifidanoid A（1）、布卢门醇C（blumenol C，2）、megastigman-5-ene-3，9-diol（3）、乌苏酸（3β-hydroxyurs-12-en-28-oic acid，4）、刺梨苷（kaji-ichigoside F1，5）、1，4-对苯二甲酸（1，4-terephthalic acid，6）、紫丁香酸（syringic acid，7）、香草酸（vanillic acid，8）、3，5-dimethoxy-4-methylbenzyl alcohol（9）。C13 nor-isoprenoids骨架类型的化合物1-3和其他5，6，9为首次从该属植物中分离得到。

Nine compounds were isolated from the aerial part of Callicarpa kwangtungensis chun by various column chromatographic methods. Their structures were identified as pinnatifidanoid A（1）, blumenol C（2）, megastigman-5- ene-3β, 9R-diol（3）, 3β-hydroxyurs-12-en-28-oic acid（4）, kaji-ichigoside F1（5）, 1, 4-terephthalic acid（6）, syringic acid（7）, vanillic acid（8）, and 3, 5-dimethoxy-4-methylbenzyl alcohol（9）on the basis of spectral analysis. C13 nor-isoprenoids of 1-3, and compounds 5, 6 and 9, were isolated from the genus Callicarpa for the first time.
