[0211] Example 3 of the present invention: 105.5g of nine lion grass, 63g of cinnabar root, 79g of salicylate root, 79g of glutinous rice root, 31.5g of golden fruit olive, 63g of bellflower, 79g of peppermint, 2.5g of menthol
[0212] Take nine lion grass, cinnabar root, water bayberry root, glutinous rice vine root, golden fruit olive, platycodon grandiflorum, mint, steam distillation to extract volatile oil, the distilled aqueous solution is collected in another device, the dregs of the medicine are decocted for 1.5 hours, filtered, and Combine the above aqueous solutions, concentrate under reduced pressure to a clear paste with a relative density of 1.10 to 1.12 at a relative density of 60°C, add ethanol to make the alcohol content reach 60%, let it stand for 24 hours, filter, and recover the filtrate under reduced pressure below 80°C for ethanol concentration, Dry, add menthol, mix evenly and pulverize into fine powder, add matrix PEG4000 according to extract powder: matri...
Embodiment 8
[0221] Example 8 TLC identification of salicylate root in dropping pills
[0222]Take 3.0g of this product powder, add methanol 50ml, ultrasonically treat for 30 minutes, filter, evaporate the filtrate to dryness, add 20ml of water to dissolve the residue, add ethyl acetate and shake and extract twice, 20ml each time, combine the ethyl acetate solution, evaporate Dry, add methanol 1ml to the residue to dissolve, as the test solution. Take another negative sample (water-deficient Myrica rubra root), and make a negative sample solution in the same way. Then take 2 g of the reference drug of Myrica rubra root, add 50 ml of ethyl acetate, ultrasonically treat it for 60 minutes, filter, evaporate the filtrate to dryness, add 1 ml of methanol to the residue to dissolve, and use it as the reference drug solution. According to the thin-layer chromatography test, draw 10 μl of each of the above two solutions, spot them on the same silica gel G thin-layer plate, use chloroform-acetone ...
