| Abstract
|
| [Objective] To optimize the extraction process of Rhizoma Picrorhizae by an orthogonal experiment and to determine the best extraction parameters. [Methods] The L9(34) orthogonal test was employed based on a multiple criteria comprehensively evaluating the yields of picroside I, picroside II, and total extracts. [Results] The optimum extraction process was characterized as: soaking the crude rhizome powders for 24 h and percolating them with 1.5 mL/min of the flow rate and 16 folds of extraction volume were collected. [Conclusion] The extraction technique is stable and available.This study provides an experimental basis for the industrial production of Rhizoma Picrorhizae. |
