Embodiment 1
[0062] Example 1 Preparation of effective components of Schisandra chinensis
[0063] 250g schisandra chinensis is crushed, add 8 times the amount of ethyl acetate:ethanol=1:1, heat and reflux for 1 hour, extract twice, add 8 times the amount of 70% ethanol to the dregs, heat and reflux for 1 hour, extract twice, and combine the filtrates to obtain the extraction After concentrating the extract, dissolve the sample with 5% methanol, and pass it through the ODS-C18 column. First, use 5% ethanol as the mobile phase, and then replace it with 50% ethanol as the mobile phase to obtain the eluent, which is used to prepare the liquid phase Chromatography continues to separate the eluent, separation conditions: the chromatographic column is an Agilent 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

[0066] The flow rate is 10ml / min, the column temperature is room...
Embodiment 2
[0067] Example 2 Analysis of Schisandra Effective Components
[0068] The HPLC-ELSD joint analysis to the effective component of Schisandra chinensis of embodiment 1
[0069] Chromatographic conditions Chromatographic column Agilent Zorbax SB-C18 column (4.6mm × 150mm, 5 μm); using gradient elution, mobile phase A is 0.2% glacial acetic acid aqueous solution, mobile phase B is acetonitrile solution containing 0.2% glacial acetic acid; gradient elution The procedure is as follows: at 0 minutes, mobile phase A is 90% 0.2% glacial acetic acid aqueous solution, mobile phase B is 10% 0.2% glacial acetic acid in acetonitrile solution; at 10 minutes, mobile phase A is 50% 0.2% glacial acetic acid Aqueous solution, mobile phase B is 50% 0.2% glacial acetic acid acetonitrile solution; 30 minutes, mobile phase A is 5% 0.2% glacial acetic acid aqueous solution, mobile phase B is 95% 0.2% glacial acetic acid acetonitrile solution; 35 In minutes, the mobile phase A was 5% 0.2% glacial ...
Embodiment 3
[0072] Example 3 Schisandra active ingredient preparation
[0073] Take any active ingredient of Schisandra chinensis in Example 1, mix 0.5g with 10.5g polyethylene glycol-6000 evenly, heat and melt, and move the material to drip irrigation after the material is made, and drop the medicine liquid to 6-8°C liquid paraffin In the process of removing oil, 400 dropping pills were prepared.
