摘要: 建立了二维高通量色谱分离、纯化海参来源真菌Epicoccum sp中的海松烷二萜化合物的新方法。以甲醇-水为溶剂体系梯度洗脱,在流速为40 mL/min、主分离检测波长为254 nm,二级分离检测波长为220 nm的条件下进行分离,从15 g海参来源真菌Epicoccum sp乙酸乙酯提取物中分离制备得到海松烷二萜化合物,通过核磁共振氢谱和质谱鉴定化合物的结构。该方法简便、快捷且减少样品的不可逆吸附,为海松烷二萜化合物的制备型分离提供了新手段。

Abstract: We established a new method for separation and preparation of pimarane diterpenes from sea cucumberderived fungus Epicoccum sp.by twodimensional highthroughput chromatography.It was performed with MeOHH2O as solvent, flow rate of 40 mL/min, main separation detection wavelength of 254 nm and second separation detection wavelength of 220 nm.Pimarane diterpenes were isolated from 1.5 g ethyl acetate extract fromsea cucumberderived fungus Epicoccum sp.Their structureswere identified by spectroscopic data (1H NMR and MS).The method is simple and rapid, reduces irreversible sample adsorption,and provides a new approach for separation and preparation of pimarane diterpenes.

Key words: sea cucumberderived fungus, pimarane diterpenes, twodimensional highthroughput chromatography
