广东紫珠的化学成分

Chemical constituents from Callicarpa kwangtungensis Chun

摘要: 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。

Abstract: 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.
