摘　　要：通过保温提取法,优选出冠突散囊菌所产黄色系物质的最佳提取工艺条件是:料液比1∶30,温度60℃,提取时间1h,最高得率可达0.83%.通过TLC法、HPLC法、紫外光谱及红外光谱法,选取β-胡萝卜素、番茄红素为标准品,进行黄色系物质结构验证分析及可能结构预测。结果表明:冠突散囊菌黄色系物质最大吸收波长为394nm,含有C-O、C=C,不含C≡C,因此不是β-胡萝卜素、番茄红素,可能是叶黄素一类.The best condition of the optimized Eurotium cristatum is：material liquid than 1 extraction process of the yellow substance from ： 30, 60 ℃, 1 h, the yield as much as 0.83% with the heat extraction method. Choose beta carotene, lycopene for standard and by the method of TLC, ultraviolet spectrometry, infrared spectroscopy, to speculate what sub- stance yellow substance may be. The results show that the maximum absorption wavelength of ultra contain are not violet is 398 nm. Through infrared spectroscopy speculate that the materials may the functional groups is C--O,C=C,not contain the C≡C. So the yellow materials the beta carotene and lycopene, may be the lutein.
