为了寻找芦丁水解制备槲皮素的最佳实验条件,为槲皮素的生产提供实验数据,采用在不同溶液中,使用不同的酸,不同浓度,加热不同的时间,观察芦丁水解的情况。实验发现:芦丁在水溶液中,使用盐酸或硫酸,酸的浓度在0.5%时,芦丁水解制备槲皮素的生产成本最低、收率高、综合效益最好。实验结果表明:在0.5%的盐酸或硫酸水溶液中,加热1h,芦丁水解制备槲皮素的收率为91.0%。
In order to find out the optimal experimental conditions for the preparation of quercetin by hydrolyzing rutin, experimental data were provided for the production of quercetin. Different concentrations of acids and different concentrations of different acids were used in different solutions to observe the hydrolysis of rutin . The results showed that rutin could be hydrolyzed to produce quercetin with the lowest production cost, high yield and the best comprehensive benefit when hydrochloric acid or sulfuric acid was used in aqueous solution. The experimental results show that the yield of quercetin prepared by hydrolysis of rutin is 91.0% when heated in 0.5% hydrochloric acid or sulfuric acid solution for 1 h.
