Embodiment 1
[0152] The preparation of the effective component of embodiment 1 Rubescens japonicus
[0153] Take 250g of Radix Oryzae, 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 was concentrated into extract to obtain 11.1g, the extract and silica gel were mixed as a sample, and separated with a normal phase silica gel column, 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 1.8 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 an Agient preparative column (Zorbax SB-C 18 ; 21.2mm × 250mm), the mobile phase is water (A) and acetonitrile (B), and the gradient elution proce...
Embodiment 2
[0156] The analysis of the effective component of embodiment 2 Rubescens japonicus
[0157] The HPLC-ELSD joint analysis of the effective components of Atractylodes Rhizome of Example 1
[0158] Chromatographic conditionsChromatographic 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 wa...
Embodiment 3
[0161] Embodiment 3 oridonium active ingredient preparation
[0162] Take the active component of Rubescens japonicus in Example 1, mix 0.5g with 10.5g of polyethylene glycol-6000 evenly, heat and melt, move the material to drip irrigation, and drop the drug solution into liquid paraffin at 6-8°C , degreasing, made 400 dropping pills.
