Abstract:
AIM: To compare the contents variation of anthraquinones by 2 kinds of extractive process of Naomaitong extract (Radix et Rhizoma rhei, Rhizoma chuanxiong, Radix et Rhizoma qinseng, Radix puerariae lobatae, etc). METHODS: In application to RP-HPLC, Hypersil ODS2 C_ 18 column, the mobile phase was a mixture of methanol- 0.1% phosphate water (75 ∶25), the wavelength of detecting five aglycons in R. officinale was at 254 nm. RESULTS: The extraction rate of anthraquinones contents extracted by alcoholic extraction was higher than water extraction, the chrysophanol content in separated decoction was higher than that in the mixed decoction. CONCLUSION: There are dynamic variations in the extraction of Chinese medicine mixture. It is necessary to handle samples appropriately according to physichemical attributes of chemical contents.
