Optimization of the Preparation Process of Atemisia rupestris L.Oral Liquid
In order to explore the best preparation process of Atemisia rupestris L.oral liquid,the total flavonoids in Atemisia rupestris L.oral liquid were extracted by water extraction and ethanol precipitation method,and the best preparation process parameters were obtained through single factor and response surface test,and the preliminary quality control of Atemisia rupestris L.oral liquid was established through thin layer chromatography and content limit determination.The results showed that the optimal preparation process for Atemisia rupestris L.was a material liquid ratio of 1∶14,a decoction time of 1.5 hours,and an alcohol precipitation concentration of 50%.In the chromatogram of the test sample,there are spots of the same color at the corresponding positions as the reference sample.The content limit of flavonoids is determined to be between 28.67 and 29.59 mg/mL,with an average value of 29.10 mg/mL and a minimum limit of 23.28 mg/mL.
