Embodiment 1
[0124] The preparation of the effective component of embodiment 1 Fangji
[0125] Crush 250g of Fangji, 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 extract After concentrating the extract, dissolve the sample with 5% methanol and pass it through the ODS-C18 column. First, use 5% methanol as the mobile phase, and then replace it with 60% methanol 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
[0126]
[0127] The flow rate is 10ml / min, the column temperature is room temperature; the sample is dis...
Embodiment 2
[0128] The analysis of embodiment 2 Fangji effective components
[0129] Combined HPLC-ELSD analysis of the effective components of Fangji in Example 1
[0130] 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 acetic acid in ...
Embodiment 3
[0133]Embodiment 3 Fangji effective component preparation
[0134] Take any effective component of Fangji in Example 1, mix 0.5g with 10.5g polyethylene glycol-6000 evenly, heat and melt, move the material to the drip irrigation after the material, and drop the medicine liquid to 6-8°C liquid paraffin In the process of removing oil, 400 dropping pills were prepared.
