Abstract:
Objective:To optimize the extraction parameters for the water extract of Tangganjian concentrated pills .Methods:U-sing the content of paeoniflorin and extraction yield as the evaluation indices .An HPLC was used to determine the content of peoniflorin in the extract, and the chromatographic conditions were as follows: a WondaSil C18 chromatographic column (250 mm ×4.6 mm, 5μm), the mobile phase was acetonitrile-0.1%phosphoric acid solution (16∶84) with a flow rate of 1 ml· min-1, the column tem-perature was 30℃and the detection wavelength was 230 nm.The amount of water , extraction time and extraction times were regarded as the influencing factors ,an orthogonal design was adopted to develop the analysis of variance for extraction parameters for water ex -tract.Results:The optimal extraction process was as follows:adding 12-fold amount of water and extracting 3 times with 1 h for each time.Conclusion:The optimum extraction process is reasonable , stable and feasible, which provides experimental basis for the extrac-tion process of Tangganjian concentrated pills .
