ABSTRACT
OBJECTIVE:
To establish the quality standard of Lithocarpus polystachys.METHODS:
TLC was used for the qualitative identification of L.polystachys.The content of total flavonoids of L.polystachys was determined by UV spectrophotometry and the content of phloridzin was determined by HPLC.RESULTS:
The TLC spots of polyamide were clear and well separated.The maximum absorption wavelength of phlorizin was 284 nm.The content of total flavonoids of 6 batches of L.polystachys ranged from 103.12 mg?g-1 to 183.54 mg?g-1.The linear ranges of phlorizin were 0.099 8~1.197 6 ?g (r=0.999 7) with an average recovery of 97.23%(RSD=1.57%,n=6).CONCLUSION:
Established quality standard is applicable for the quality control of L.polystachys.
