摘要
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 provide experimental data for producing quercetin, the effects of various factors on the hydrolytic decomposition of rutin were studied, such as various solutions, different kinds of acid with different concentrations and heating time. It is found that in the water solution the cost of producing quercetin by hydrolytic decomposition of rutin is lower, the yield is higher, and the general benefit is the best. The yield can reach 91.0% when uses 0.5% chlorhydric acid or sulfuric acid aqueous solution and heats for 1h.
