Evaluation for Merchandise Character and Quality of Bupleurum chinense Root from Different Habitats

目的:评价不同产地柴胡药材质量。方法:随机购置不同产地柴胡,测定根及残茎质量。用分光光度计法分别测定柴胡中总皂苷和总黄酮的含量;采用热浸法、灰分测定法分别测定醇溶性浸出物、总灰分的含量。结果:不同产地柴胡品质相差很大,同一产地选装货与统装货之间也存在差异(P<0.05)。以江苏通安统装货质量最好,其根长、根粗、单株重、残茎所占总长比例、总皂苷、总黄酮、醇溶性浸出物、总灰分分别为14.60 cm/株、0.59cm/株、5.14 g/株、36.85%、0.721%、0.615%、12.993%、4.890%。结论:供试的不同产地商品柴胡中,以江苏通安统装货柴胡药材品质最好。

Objective：To evaluate the merchandise character and quality of Bupleurum chinense root from different habitats. Meth- ods ：The spectrophotometer method was used to determine the content of total saponins and total flavonoids in Bupleurum chinense root. The content of alcohol-soluble extract and total ash were determined according to the method in the Chinese Pharmacopoeia. Results： The quality of Bupleuri Radix from different habitats varied greatly. There were also differences（P 〈 0. 05）be- tween the merchandise packaged with selection and the merchandise packaged without selection of Bupleurum chinense root from the same habitats. The merchandise packaged without selection had the better quality,whose root length,root diameter,weight, total length proportional share of residual stems, total saponins, total flavonoids, total alcohol-soluble extract and total ash was 14. 50 cm/plant ,0. 59 cm/plant,5.14 g/plant,36. 85% ,0. 721% ,0. 615%, 12. 993% and 4. 890% ,respectively. Conclusion：Bupleurum chinense root from Tong＇an,Jiangsu has the best quality in the test samples from different habitats.
