葱莲的化学成分研究

Studies on Chemical Constituents from Zephyranthes candida

目的：研究石蒜科葱莲属植物葱莲Zephyranthes candida全草中的化学成分。方法：采用反复硅胶柱色谱进行分离、纯化，根据理化性质和波谱数据进行结构鉴定。结果：从葱莲中分离得到8个化合物，分别鉴定为（2S）-3，7-二羟基-4’-甲氧基黄烷（Ⅰ）、β-谷甾醇（Ⅱ）、△^5.22-豆甾烯醇（Ⅲ）、豆甾醇（Ⅳ）、β-胡萝卜苷（Ⅴ）、邻苯二甲酸丁酯异丁酯（Ⅵ）、正二十七烷（Ⅶ）和黄葵内酯（Ⅷ）。结论：化合物Ⅰ～Ⅷ均为首次从该属植物中分离得到。

Objective ： To study on the chemical constituents of Zephyranthes candida. Methods ： Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column. Their structures were elucidated by chemical and spectral methods. Results ： Eight compounds were isolated from the whole plant of Zephyranthes candida, and identified as （2S） -3＇, 7-dihydroxy- 4＇-methoxyflavan （ Ⅰ ）, β-sitosterol （ Ⅱ ） , stigmasta-5,22-dien-313-ol （ Ⅲ ）, stigmasterol （ Ⅳ ） , 13-daucosterin （ Ⅴ ）, Butylisobutyl phthalat （ Ⅵ ） , Heptacosane（ Ⅶ ） and Ambrettolide（Ⅷ）. Conclusion： Ⅰ - Ⅷ are all isolated from this plant for the first time.
