目的:研究海南大风子叶的化学成分。方法:采用硅胶柱层析和Sephadex LH-20凝胶柱层析进行分离纯化,通过理化性质和波谱数据分析进行结构鉴定。结果:从海南大风子叶的乙酸乙酯浸膏中分离了9个化合物,分别鉴定为:粘霉烯醇(Ⅰ)、羊齿烯醇(Ⅱ)、羽扇豆醇(Ⅲ)、a-香树素(Ⅳ)、2,9-二甲基-2,8-葵二烯(Ⅴ)、植烯(Ⅵ)、植醇(Ⅶ)、3,7,11,15-四甲基-1,2-十六烷二醇(Ⅷ)、3,5-二甲氧基-4-羟基苯甲醛(Ⅸ)。结论:所有化合物均为首次从该植物中分离得到。 Objective: To study the chemical constituents of Calendula officinalis in Hainan Province. Methods: The constituents were separated and purified by silica gel column chromatography and Sephadex LH-20 gel column chromatography. Their structures were identified by physico-chemical properties and spectral data analysis. Results: Nine compounds were isolated from the ethyl acetate extract of P. angustifolia, identified as: Myzusol (Ⅰ), sheep allenol (Ⅱ), lupine alcohol (Ⅲ), a- (Ⅳ), 2,9-dimethyl-2,8-azetidine (Ⅴ), phytol (Ⅵ), phytol (Ⅶ), 3,7,11,15-tetramethyl- 2-hexadecanediol (VIII), 3,5-dimethoxy-4-hydroxybenzaldehyde (IX). Conclusion: All the compounds were isolated from this plant for the first time.
