黄连中盐酸小檗碱不同提取工艺的比较研究

Comparative study of different extraction technologies of berberine hydrochloride in Coptis Chinensis

以黄连中盐酸小檗碱的提取效率和纯度为指标,对乙醇回流浸提法、硫酸常温浸提法和超声波辅助萃取法进行比较.结果发现乙醇回流浸提法、硫酸常温浸提法及分别以乙醇、硫酸为溶剂的超声波辅助萃取法的提取率为2.7%、2.6%、3.1%和3.5%,产品纯度为79.01%、89.81%、85.21%和95.91%.超声波辅助萃取法具有简便快速和节能高效的优点,是一种值得在工业上推广的提取新工艺.

The efficiency and the purity of the berberine hydrochloride in coptis chinensis were as index to compare the aqueous ethanol refluxing method, the sulfuric acid ambient temperature extraction method and the ultrasonic assisted extraction method. The yield of berberine hydrochloride by the aqueous ethanol refluxing method, the sulfuric acid ambient temperature extraction method and the ultrasonic assisted extraction method, which was with ethanol and sulfuric acid as solvent, was 2.7%, 2.6%, 3.1% and 3.5%, and the purity was 79.01%, 89.81%, 85.21% and 95.91%. The ultrasonic assisted extraction method is a new extraction method that is worth popularizing in industry for simplicity, celerity and high efficiency.
