| Abstract: | Objective： To study extract technology for effective ingredient of Radix Astragali by Orthogonal Experiment, the purpose promotes mass detection method of Radix Astragali.nethod ： The extract technology were used Orthogonal Experiment by L9 （ 34 ） .The research factors were determined Alcohol concentration, Alcohol dosage, extract time and extract frequency.The effective ingredient of Radix Astragali were observed for Astragaloside 1V and Calycosin Glucoside, which they were index for extraction rate.Result： The 10 volume times alcohol, 80% concentration alcohol, 2 recirculation times and one time of 1 hour were discovered for optimization technology. Conclusion： The extract condition be sure to stable and reasonable. That can be to make use of extraction in effective ingredient and quality control method for Radix Astragali. |
