摘要:

采用现代多种色谱技术对劲直刺桐Erythrina strica Roxb枝叶的乙酸乙酯萃取物进行化学成分分离纯化, 得到15个化合物, 化合物类型涉及倍半萜、三萜、甾体、木脂素等, 利用波谱技术和文献对照鉴定它们的结构分别为: loliolide (1), phaseic acid (2), pinnatififidanoid A (3), soyasapogenol E (4), 大豆皂醇B (5), 2α,3α,19α,23-tetrahydroxyurs-12-en-28-oic acid (6), 3β,22β,24-trihydroxyolean-12-en-29-oic acid (7), (23Z)-9,19-环阿尔廷-23-烯-3β,25-二醇 (8), 3,4-二羟基苯甲酸 (9), (+)-丁香脂素 (10), (E)-4-hydroxy-dodec-2-enedioic acid (11), lutein (12), 7β-羟基豆甾醇(13), β-谷甾醇(14), 胡萝卜苷 15)。其中倍半萜类成分为首次报道从刺桐Erythrina属植物中得到; 除了化合物1315外, 其余化合物皆是首次从该植物中分离得到。

Abstract:

A total of 15 compounds were extracted from the ethyl acetate extraction of the twigs and leaves of Erythrina strica. Based on NMR spectral data, their structures were identified as loliolide (1), phaseic acid (2), pinnatififidanoid A (3), soyasapogenol E (4), soyasapogenol B (5), 2α,3α,19α,23-tetrahydroxyurs-12-en-28-oic acid (6), 3β,22β,24-trihydroxyolean-12-en-29-oic acid (oxytrogenin) (7), (23Z)-9,19-cycloart-23-ene-3β,25-diol (8), 3,4-dihydroxybenzoic acid (9), syringaresinol (10), (E)-4-hydroxy-dodec-2-enedioic acid (11), lutein (12), ergosterol-5,8-peroxide (13), β-sitosterol (14), and daucosterol (15). Except for compounds 1315, all the compounds were isolated from this plant for the first time. Moreover, sesquiterpenoids were isolated from Erythrina genus for the first time.

Key words: Erythrina, Erythrina strica, Sesquiterpenoid
