Embodiment 1
[0068] Example 1 Preparation of effective components of Schisandra chinensis
[0069] Take 250g of Schisandra chinensis, crush it, add ethyl acetate and ethanol (1:1), heat to reflux for 1 hour, extract twice, and combine the filtrates to obtain the extract. Concentrate the extract into extract to obtain 8.6g, dissolve and load the sample with ethanol, and pass through the ODS-C18 column. First, use 1250ml of 30% ethanol as the mobile phase to obtain the eluate, discard it, and then replace it with 1250ml of 95% ethanol as the mobile phase. phase to obtain eluent II, and concentrate and dry the eluent II to obtain a sample; continue to separate the sample obtained by preparative liquid chromatography; separation conditions for preparative chromatography: the chromatographic column is a preparative column Zorbax SB-C18; 21.2mm×250mm , the mobile phase is water A and acetonitrile B, and the gradient elution procedure is as follows:
