To analysis of different provenances of radix bupleuri medicinal materials quality using field planting test, and to determine the provenance of suitable cultivation of radix bupleuri in Beijing. Methods:Field experiment was set in Shunyi district of Beijing, growing 3 provenances of radix bupleuri bought from Hebei Anguo medicine market, Anhui Bozhou medicine market and Chinese academy of medical sciences institute of medicinal plant. By ultraviolet-visible spectrophotometry and high performance liquid chromatography (HPLC) method, total saponins in radix bupleuri, radix bupleuri saponins (a,b and c) were measured. Compared with those cultivated in Gansu and Shanxi, those three different provenance of radix bupleuri medicinal materials’ quality were evaluated. Results:Three different provenance of radix bupleuri had few difference comparing with those cultivated in Gansu and Shanxi in total saponins in radix bupleuri,and radix bupleuri saponins (a,b and c), besides, it met with Chinese pharmacopoeia standards, in which product of Hebei Anguo medicine market and Chinese academy of medical sciences institute of medicinal plant shared better quality.Conclusion:Beijing is suitable for planting of radix bupleuri, and provenance from hebei anguo medicine market or the Chinese academy of medical sciences institute of medicinal plant can be purchased.
