【摘要】 采取甲醇多步结晶法 ,从海星(Asteriasamurensis)中分离精制了海星甾醇。利用高效液相色谱 ,对海星甾醇中的胆甾醇含量进行了测定。研究结果表明 ,在选定的色谱条件下 ,胆甾醇测定结果线性良好 ,精密度好 ,准确度高。这为制定海星甾醇的质量标准提供了参考依据更多还原

【Abstract】 Multilevel fractional crystallization was used to separate sterols from Starfish(Asterias amurensis),and the content of cholesterol was determined by HPLC.Under selected chromatography conditions,the cholesterol can be determined accuˉrately and rapidly.The result shows this proposed method has provided a reference basis for making the quality control standards for cholesterol from Starfish(Asterias amurensis).更多还原
