A new identification and quautitation method for radix Salviae miltiorrhizae

Objective:To develop an identitication and quantitation method for Radix Salviae Miltiorrhizae.Method:The powder X-ray Diffraction Fourier Fingerprint Pattern technique was used for this purpose.The high performance liquid chromatography method was used to evaluate the quantity of Tanshinone ⅡA in 9 samples and 1 drug reference substance.The relationship of diffraction peak intensity and content of Tanshinone ⅡA was investigated.Result and Conclusion:The powder X-ray diffraction Fourier Fingerprint Pattern analysis technique can be used to identify Radix Salviae Miltiorrhizae and to evaluate the quantity of Tanshinone ⅡA in the drug at the same time.
