coptis n.【植物;植物學】黃連;〔C-〕黃連屬。

copula

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:采用正交設計法,以槲皮素、原兒茶醛薄層斑點,延胡索乙素含量為指標,優選提取工藝。

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 結果:最優提取工藝為中等粒度的醋延胡索, 50 %的乙醇, 8倍溶劑量,提取2次,高溫減壓濃縮。

The result showed that the most suitable shadings for coptis chinensis franch of 3 , 4 and 5 - age years are 60 % , 45 % , 0 同一蔭蔽度下不同年齡黃連抗性物質有著明顯差異。
