Embodiment 1
[0082] The preparation of embodiment 1 andrographis paniculata effective components
[0083] Take 250 g of Andrographis paniculata, grind it, add ethyl acetate and ethanol (1:1), heat and reflux for 1 hour, extract twice, and combine the filtrates to obtain the extract. The extract was concentrated into extract to obtain 15.5g, 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 1.7 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 el...
Embodiment 2
[0086] The analysis of embodiment 2 Andrographis paniculata effective components
[0087] (1) HPLC-ELSD analysis of the Andrographis paniculata effective component of embodiment 1
[0088] 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...
Embodiment 3
[0091] Embodiment 3 andrographis paniculata active ingredient preparation
[0092] Take 0.5 g of the effective components of Andrographis paniculata in Example 1 and mix them evenly with 10.5 g of polyethylene glycol-6000, heat and melt, move the material to drip irrigation, drop the drug solution into liquid paraffin at 6-8°C, and remove the oil , made 400 dropping pills.
