Objective:To improve the quality standard of Toona sinensis seeds.Method:By TLC,impurity,moisture,extracts,content determination and so on to examine the Toona sinensis seeds.Results:TLC was clear and easy to recognize.Impurity:the lowest value is 5.76%,the highest value is 19.89%,and the average value is 12.92%.Moisture content is determined by the toluene method,the lowest value is 7.89%,the highest value is 9.94%,and the average value is 8.67%.The extract is extracted using dilute ethanol as the solvent,and the hot leaching method is used as the leaching method,the lowest value is 12.63%,the highest value is 22.58%,and the average value is 17.66%.Content determination with gallic acid as the target ingredient,showed a good linearity in the range of 9.26 µg/mL～185.20µg/mL,the minimum value of 10 batches of samples is 1.54%,the maximum value is 4.88%,and the average value is 3.56%.Conclusion:The results might be used as important indicators for the quality standard of Toona sinensis seeds.
