Objective:To revise and improve quality standards of Wikstroemia chamaedaphne. Method: According to research methods of 2010 edition of Chinese Pharmacopoeia appendix
microscopic and TLC of W. chamaedaphne was identified
impurities
moisture
ash
acid insoluble ash and the content of active ingredients in 10 batches of W. chamaedaphne were determined. Result: Microscopic characteristics and TLC identification of W. chamaedaphne was determined and established;Moisture limit and impurities limit of W. chamaedaphne were ≤11.0%
acid insoluble ash limit ≤1.0%
ash limit ≤9.0%
the mass fraction of luteolin in 10 batches of W. chamaedaphne was 0.10-1.40 mg·g-1. Conclusion: This study improved quality standard of W. chamaedaphne
