中文摘要: 建立硅胶柱层析法分离制备栀子黄色素中藏红花素I的方法,并对所得产品进行抗氧化性与稳定性研究。建立了乙酸乙酯-甲醇-水(体积比为100∶20∶15至100∶25∶15)的梯度洗脱体系,以及层析柱硅胶与栀子黄色素的质量比为350∶1的上样量比例,并制备出纯度为98.39%的藏红花素I单体样品,其得率为15.58%,回收率为50.42%。抗氧化与稳定性研究结果表明,藏红花素I具有优良的抗氧化活性;藏红花素I在高温、强光照射、强酸强碱环境中均会产生损失。含藏红花素I成分的产品应贮存于低温、避光、pH值为6的环境中,且与适量抗坏血酸联用可以提高其稳定性。
Abstract:To establish a method for the separation and preparation of crocin I from gardenia yellow pigment by silica gel column chromatography,and to study the antioxidation and stability of the obtained product.Established a gradient elution system was ethyl acetate-methanol-water(100∶20∶15 to 100∶25∶15 by volume)and the optimal proportion of the loading amount was the mass ratio of silica gel to gardenia yellow pigment with 350 ∶1,and a 98.39%purity sample of crocin I was prepared with a yield of 15.58%and a recovery rate of 50.42%.The results of antioxidant and stability studies showed that crocin I had excellent antioxidant activity,and crocin I was lost in high temperature,strong light,strong acid and alkali environment.The products containing crocin I should be stored in an environment with low-temperature,light-proof,pH 6,and can be used in combination with an appropriate amount of ascorbic acid to improve its stability.
