[Study on preparation and determination of Liaojin plastics].
OBJECTIVE
To establish the optimum preparation and determination method of Liaojin plastics through screening different factors.


METHODS
The Orthogonal Test was applied to optimize the best preparation technology, and the content of peoniflorin in Liaojin plastics was determined by HPLC.


RESULTS
The best matrix proportion of plastics was PVA-124 : alcohol : acetone : distilled water = 1 : 4 : 2 : 10; The average recovery of plastics was 98.56%, RSD was 1.66% (n = 9), and the average content of six samples was 0.6817 mg/g, RSD was 1.44%.


CONCLUSIONS
The good quality plastics can be produced through this process. HPLC determination method is simple, reliable and can be used in the quality control of Liaojin plastics.
