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 ...
