不同栽培模式下黄连质量评价

Quality assessment for Coptis chinensis with different cultivating system

目的：评价4种不同栽培模式下黄连的质量。方法：连续2年选取简易棚下、柳杉林下、白马桑林下、厚朴林下4种栽培模式下的黄连样品，采用紫外．可见分光光度法、高效液相色谱法分别测定其总生物碱和盐酸小檗碱的含量。结果：4种栽培模式下黄连总生物碱含量和盐酸小檗碱含量均无明显差异，总生物碱的含量变化幅度在13．88％～17．41％，盐酸小檗碱在6．95％～9．47％，均显著高于药典1990年版对黄连中总生物碱的含量的规定（7．0％）和药典2005年版对黄连中盐酸小檗碱含量的规定（3．6％）。结论：4种栽培模式下的黄连根均可作为黄连药材入药，且质量较好。

Objective： To evaluate the quality of Coptis chinensis planted with four kinds of cultivating system. Method： The samples, which were planted below the artificial shading, the forest of Chinese ceder wood, Mmulbery wood, Magnolia officinal wood were chosen respectivley, UV and HPLC were used to determine of total alkaloids and berberine of samples. Result： There was no sig- nificant difference among four kinds of cultivating system on the contents of total alkaloids and berberine. The contents of total alkaloids and berberine were obviously higher than in the criterion of Chinese Pharmacopoeia. Conclusion： The roots of C. chinensis planted in the four kinds of planting system can be used as medicinal material of high quality.
