Objective:To establish quality control specification of Drymaria cordata
and provide experimental basis for developing and utilizing of this medicinal plant resources. Method: Property identification
microscopic identification were used to identify pharmacognostical characteristics of D. cordata by TLC
sample volume was 5 μL
developing agent was cyclohexane-chloroform-acetic ether-formic acid(20: 3: 8: 0.3).Moisture
total ash and extract content were determined. Result: Morphological and histological characters of D. cordata from different origins showed good consistency.TLC identification was distinct with strong specificity.Quality standards of this product was set as following:moisture≤12.0%
total ash≤13.0%
content of alcohol soluble extract≥18.0%. Conclusion: This established method can be used for quality criteria of D. cordata.
