- Abstract:
- To investigate the difference of total flavonoids and puerarin in pueraria lobata from Hunan， Shaanxi，Hubei and Shanxi，so as to lay a scientific foundation for resource optimization and rational use． Method: The content of total flavonoids in pueraria lobata was determined by UV － vis spectrophotometry，and the content of puerarin in pueraria lobata was determined by HPLC． Ｒesult: The total flavonoids in pueraria lobata from four areas of Hunan， Shaanxi，Hubei and Shanxi were 6． 13% ，7． 24% ，14． 33% and 13． 71% ，respectively． The contents of puerarin in pu- eraria lobata were 2． 13% ，2． 82% ，5． 61% and 4． 76% ，respectively． Conclusion: The contents of total flavonoids and puerarin in pueraria lobata in four producing areas of Hunan，Shaanxi，Hubei，and Shanxi were quite different，high con- tent of total flavonoids corresponds to high puerarin． It is feasible to use total flavonoids and puerarin as indexes for evalua- tion of pueraria lobata． The pueraria lobata in Hubei is the best，followed by Shanxi，Shaanxi and Hunan． It provides a scientific reference for rational use and resource evaluation of medicinal materials．
