Research on Improving the Quality Standards of Zanthoxylum Slices
OBJECTIVE To supplement,revise,and improve the inspection and content determination items for moisture,total ash,extract,and content determinationin Zanthoxylum slices according to the 2020 edition of the Chinese Pharmacopoeia.METHODS Fifteenbatches of Zanthoxylum slices were collectedand analyzed using the toluene method for moisture determination,the 2302 ash content determination method,the 2201 extract determination method,and method A of 2204 volatile oil determination from the 2020 edition of the Chinese Pharmacopoeia.RESULTS The moisture content of 15 batches of Zanthoxylum sliceswas(7.64±0.99)％,total ash was(5.62±0.47)％,acid-insoluble ash was(0.23±0.13)％,extract content was(32.87±1.98)％,and volatile oil content was(2.59±0.46)％.CONCLUSION The limit value for Zanthoxylum set based on a 20％increase in the average moisture and total ash contentand a 20％decrease in the average leachate and volatile oil content:moisture should not exceed 9.5％,total ash should not exceed 7.0％,no limit for acid-insoluble ash is established,leachate should not be less than 26.0％,and volatile oil content should not be less than 2.0％(mL·g-1).
