Embodiment 1
[0098] The preparation of the effective component of embodiment 1 Radix Paeoniae Rubra
[0099] Take 250 g of Radix Paeoniae Rubra, 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. The extract is concentrated into extract to obtain 16.0g, the extract and silica gel are mixed as a sample, and the normal phase silica gel column is used for separation, at first using sherwood oil and ethyl acetate (50: 1) as mobile phase to obtain eluent I, Then, chloroform and methanol (10:1) were used as the mobile phase to obtain the eluent II, which was concentrated and dried to obtain 2.1 g of the sample. The separation of the resulting sample was continued by preparative liquid chromatography. Separation conditions for preparative chromatography: the chromatographic column is a Hanbang semi-preparative column (Lichrospher C18; 10.0mm×250mm, 5 μm), the mobile phase is water (A) and acetonitrile (B), and...
Embodiment 2
[0102] The analysis of the effective component of embodiment 2 Radix Paeoniae Rubra
[0103] The HPLC-ELSD joint analysis to the effective component of Radix Paeoniae Rubra of Example 1
[0104] 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 w...
Embodiment 3
[0107] Embodiment 3 Radix Paeoniae Rubra Active Component Preparation
[0108] Take 0.5 g of the effective component of Radix Paeoniae Rubra in Example 1 and mix evenly with 10.5 g of polyethylene glycol-6000, heat and melt, and move the material to drip irrigation after the material is made, and drop the medicine liquid into the liquid paraffin at 6-8 ° C, remove Oil, made 400 drop pills.
