目的:研究柳珊瑚Dichotella gemmacea的化学成分。方法:采用硅胶柱色谱及Sephadex LH-20凝胶柱色谱和高效液相色谱分离、纯化。根据理化性质和光谱数据鉴定其结构。结果:从柳珊瑚的醇提物中分离纯化得到8个化合物,分别鉴定为:fragilide J(Ⅰ)、junceelldide D(Ⅱ)、junceellin A(Ⅲ)、juncin P(Ⅳ)、dichotellides A(Ⅴ)、cerevisterol(Ⅵ)、1,2-二苯基二硒烷(Ⅶ)和五氢吡啶并[4,3-b]吲哚(Ⅷ)。结论:其中,化合物Ⅵ、Ⅶ和Ⅷ为首次从柳珊瑚Dichotella gemmacea中分离得到。
Objective: To study the chemical constituents of Dichotella gemmacea Methods: Silica gel column chromatography and Sephadex LH-20 gel column chromatography and high performance liquid chromatography separation and purification. The structure was identified based on physico-chemical properties and spectral data. Results: Eight compounds were isolated and purified from the alcoholic extracts of Salix psammophila and identified as fragilide J (Ⅰ), junceelldide D (Ⅱ), junceellin A (Ⅲ), juncin P (Ⅳ), dichotellides A , Cerevisterol (Ⅵ), 1,2-diphenyldiacetan (Ⅶ) and pentahydropyrido [4,3-b] indole (Ⅷ). Conclusion: Among them, compounds Ⅵ, Ⅶ and Ⅷ were isolated from Dichotella gemmacea for the first time.
