Objective:
To study quality standards of 10 batches of Indian of stringbush root decoction pieces with sweat processing and build up the quality standard.
Methods:
10 batches of indian stringbush root decoction pieces with sweat were investigated with TLC. Moisture content, total ash, acid-insoluble ash and extractum were explored. The content of daphnoretin was determined by HPLC.
Results:
Indian stringbush root decoction pieces with sweat,the moisture content should not pass 14.5%, total ash should not pass 3.5%, acid-insoluble ash should not pass 1.0%, alcohol-soluble extractive should not lower than 9.0%, the content of daphnoretin should not lower than 0.2%.
Conclusion:
Quality control quantization evaluation system of Indian stringbush root decoction pieces with sweat is establishment initial.
