Embodiment 1
[0113] Embodiment 1 Preparation of effective components of reed rhizome
[0114] Take 250 g of reed rhizome, 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:
[0115]
[0116] The flow rate is 10ml / min, the column...
Embodiment 2
[0117] Example 2 Analysis of effective components of reed rhizome
[0118] The HPLC-ELSD joint analysis to the reed rhizome effective component of embodiment 1
[0119] 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...
Embodiment 3
[0122] Example 3 Reed Rhizome Active Component Preparation
[0123] Take the effective component of reed rhizome of Example 1, mix 0.5g with 10.5g of polyethylene glycol-6000 evenly, heat and melt, move the material to the drip irrigation after the material, drop the medicine liquid into the liquid paraffin at 6-8°C, Degreasing, made 400 dropping pills.
