广东紫珠中咖啡酰基苯乙醇苷类化合物

Caffeoyl phenylethanoid glycosides from Callicarpa kwangtungensis

应用各种色谱技术对广东紫珠中咖啡酰基苯乙醇苷类化合物进行分离纯化,采用NMR和质谱等波谱学手段对单体化合物进行结构鉴定。从广东紫珠地上部位的醇提物中共分离得到10个咖啡酰基苯乙醇苷类化合物,鉴定为2'-乙酰基毛蕊花糖苷(1),管花苷E(2),毛蕊花糖苷(3),管花苷B(4),异毛蕊花糖苷(5),alyssonoside(6),2'-乙酰基连翘酯苷B(7),江藤苷(8),连翘酯苷B(9),金石蚕苷(10)。化合物4是首次从马鞭草科植物中分离得到,化合物6是首次从紫珠属植物中分离得到,化合物1,2,5,7均为首次从该植物中分离得到。

Phytochemical investigation on the EtOH extract from the aerial part of Callicarpa kwangtungensis led to the isolation and characterization of 10 caffeoyl phenylethanoid glycosides, 2＇-acetylacteoside （ 1 ）, tubuloside E （2）, acteoside （3）, tubuloside B （4）, isoaeteoside （5）, alyssonoside （ 6）,2＇-aeetylforsythoside B （7）, brandioside （8）, forsythoside B （ 9 ）, and poliumoside （10）. Compound 4 was isolated from the plants of Verbenaceae, and 6 was obtained from the Callicarpa genus, for the first time, while compounds 1,2,5 and 7 were firstly reported from the plant.
