摘要
目的:研究紫草乙醇浸膏的精制方法。方法:碱溶酸沉法,大孔树脂吸附法,超临界CO2萃取法,含水乙醇-石油醚萃取法,铜盐络合法。结果:以外观性状、收率和萘醌总色素的含量为指标,对5种方法所得精制产品进行了比较。结论:含水乙醇-石油醚萃取法较适于工厂生产中紫草乙醇浸膏的精制。
Objective: To study the methods for purifying the ethanol - extracts of radix arnebiae. Methods : (Ⅰ) pH control, (Ⅱ) adsorption by macro - porous resin, (Ⅲ) super critical carbon dioxide extraction, (Ⅳ) liquid - liquid extraction between ethanol (contained water) and petroleum ether, (Ⅴ) cupric salt complexometry. Result: Samples from five methods were evaluated in term of physic status, yield and the content of total hydroxyl naphthoquinones. Conclusion : IV is a fit method to purify the ethanol - extracts of gromwell in factory.
