Embodiment 1
[0013] Take 10 pieces (6.5cm×5cm) or 5 pieces (7cm×10cm) of Huoxuezhitong ointment, add 100ml of chloroform and soak for 30 minutes, stir to remove the ointment, pour out the ointment, add 50ml of methanol, stir, and let it stand for 5 minutes. Pour out the medicinal solution, evaporate to dryness below 80°C, add 2ml of methanol to the residue, stir thoroughly, centrifuge (10000 rpm) for 2 minutes, and use the supernatant as the test solution;
[0014] Take 0.5 g of Angelica as the reference medicinal material, add 20 ml of absolute ethanol to reflux for 30 minutes, let cool, filter, evaporate the filtrate to dryness, add 1 ml of methanol to dissolve the residue as the reference medicinal material solution, and use thin-layer chromatography (Appendix VIB, Part I, Chinese Pharmacopoeia 2005 Edition) For the test, draw 10 μl of the test solution and 5 μl of the control medicinal material solution, respectively spot on the same silica gel G thin-layer plate, use cyclohexane:ethyl ...
Embodiment 2
[0016] For the preparation of test solution reference, refer to Example 1;
[0017] Take hesperidin reference substance, add methanol to make a saturated solution, as the reference substance solution. Test according to thin layer chromatography (Appendix VIB of Chinese Pharmacopoeia in 2005), draw and identify 10 μl of the test solution under item (1), and 5 μl of the reference substance solution, and place them on the same silica gel prepared by 0.5% sodium hydroxide solution respectively. On G thin-layer board, use ethyl acetate:methanol:water ratio of 100:17:13 as the developer, develop to about 10cm, take it out, dry it in the air, spray with aluminum chloride test solution, and heat at 105°C After 5-10 minutes, put it under the ultraviolet lamp (365nm) to check, in the chromatogram of the test product, on the position corresponding to the chromatogram of the reference product, there will be fluorescent spots of the same color.
Embodiment 3
[0019] Take 20 pieces (6.5cm×5cm) or 10 pieces (7cm×10cm) of Huoxue Zhitong ointment, add 100ml of ether and soak for 30 minutes, stir to remove the ointment, pour out the ointment, add 50ml of ether to the residue and stir, combine the ether solution, add methanol 30ml, stir while adding, let stand for 5 minutes, pour out the liquid medicine, steam until about 5ml is left, add 20ml of 5% sulfuric acid solution, stir well, filter, add concentrated ammonia test solution to the filtrate to make it alkaline, add 20ml of diethyl ether to shake Shake, separate the ether solution, evaporate to dryness, add 1ml of absolute ethanol to the residue to dissolve, concentrate to 0.2ml, and use it as the test solution;
[0020] Take atropine sulfate reference substance, add absolute ethanol to make a solution containing 2mg per 1ml, as the reference substance solution. Test according to thin-layer chromatography (Appendix VIB of "Chinese Pharmacopoeia" in 2005), draw 20 μl of the test solut...
