To dig coptis with a hoe ? dig 拿锄头刨黄连? ?挖苦。
The studies of extraction process of berberine hydrochloride in coptis chinensis franch 黄连中盐酸小檗碱提取工艺探究
The result showed that the most suitable shadings for coptis chinensis franch of 3 , 4 and 5 - age years are 60 % , 45 % , 0 同一荫蔽度下不同年龄黄连抗性物质有着明显差异。
Results : the optimum extraction process was as follows , adding 8 times of 50 % alcohol into coptis meal , refluxing and extracting for 2 times , one hour every time 结果:最优提取工艺为中等粒度的醋延胡索, 50 %的乙醇, 8倍溶剂量,提取2次,高温减压浓缩。
Methods : using orthogonal design method , to apply extract yield of rhizoma coptis and the extract amount of berberine hydrochloride as observing indexes , to measure the content of dl - tetrahydropalmatine with hplc 方法:采用正交设计法,以槲皮素、原儿茶醛薄层斑点,延胡索乙素含量为指标,优选提取工艺。
