摘　　要：以丝棉木果实为试材,研究其果肉萃取黄色素方法及其稳定性,以期找出萃取丝棉木果肉黄色素的最佳方案。结果表明:乙酸乙酯是制备丝棉木黄色素的最佳萃取剂,而乙醇可以作为研究色素稳定性时的萃取剂,最佳萃取时间为2h,萃取温度为40℃,料液比为1:5。Taking fruit of Euonymus maackii Rupr as test material,the extraction method of Euonymus maackii and its stability ware studied completely to find out the best method of extracting the flesh pigment of E.maackii.The results showed tha ethyl acetate was the best extractant of extracting yellow pigment of E.maackii,and ethanol was better extractant of studying pigment stability.The best extracting time and temperature was respectively 2 h and 40℃,the ratio of feed to liquid was 1:5.
