红树植物尖瓣海莲的化学成分研究

目的：为了寻找红树植物尖瓣海莲不同于陆生植物的次生代谢产物及其民间治疗疟疾的物质基础,对其进行了化学成分研究。方法：采用多种色谱方法进行分离纯化,波谱方法结合文献对照鉴定结构。结果：分离并鉴定了6个三萜类化合物：羽扇豆醇(1)、羽扇豆酮(2)、 反式对羟基桂皮酰基羽扇豆醇(3)、 蒲公英萜酮(4)、β-香树脂醇棕榈酸酯(5)和鲨烯(6)及3个甾体类化合物：β-谷甾醇(7)、胡萝卜苷(8)和7α-hydroxy-sitosterol (9)。结论：化合物1～9均为首次从该植物中获得。

Compounds from marine mangrove plant Bruguiera sexangula var. rhynchopetala

OBJECTIVE: To investigate the chemical constituents in Bruguiera sexangula var. rhynchopetala. METHOD: Silica gel flash chromatography together with Sephadex LH - 20 were performed for the isolation and purification of the petrol ether fraction of this plant, and the structures were elucidated by spectral analysis as well as the comparison of the spectral data with those reported in the literatures. RESULT: Nine compounds were obtained and identified as lupeol (1), lupeone (2), trans-hydroxy-cinnamoyl ester of lupeol (3), taraxerone (4), beta-amyril-palmitate (5), squalene (6),beta-sitosterol (7), daucosterol (8) and 7alpha-hydroxy-sitosterol (9). CONCLUSION: All the compounds were first isolated from B. sexangula var. rhynchopetala.
