Objective: To establish the quality control methods of adjuvant black beans and that in Radix Polygoni Multiflori preparata. Method: By comparing differences of HPLC chromatogram of black beans.Radix Polygoni Multiflori preparata without adjuvant and processing with black beans

to determine quality control index of adjuvant black beans. On this basis

to establish the detection method of black beans in Radix Polygoni Multiflori preparata and the quality control method of raw black beans. Result: Comparison by HPLC chromatogram

detected in trace daidzein in Radix Polygoni multiflori preparata with adjuvant

and then established the TLC Chromatography of black bean in Radix Polygoni Multiflori preparata. On the other hand

HPLC determination method of assaying daidzein in raw black beans has been established. Black beans from 12 different areas were determined

that from Guangdong province was the highest content of all. Conclusion: This method could be used as the quality control methods of adjuvant black beans and that in Radix Polygoni Multiflori Preparata.
