Embodiment 1
[0031] Example 1: Methodological investigation on the cleanliness testing standard of Yiqitongluo granule production equipment
[0032] Yiqi Tongluo Granule is a Chinese patent medicine for treating stroke. It is made from astragalus, salvia miltiorrhiza, chuanxiong, safflower and earthworm according to the following method:
[0033] Weigh the decoction pieces of Danshen and Chuanxiong according to the prescription, add 3 times the amount of 70% ethanol to soak three times, each time for 48 hours, combine the ethanol extract, filter, recover the ethanol until it has no alcohol smell, and set aside. Add 8 times the amount of water to the medicinal dregs, astragalus, earthworm coarse grains and safflower medicinal materials, decoct three times for 1 hour each time, combine the decoction, filter, concentrate the filtrate, combine with the alcohol extraction part, and continue to concentrate until the relative density is 1.25—1.30 (80°C) clear ointment. Take the clear paste and a...
Embodiment 2
[0066] Example 2: Cleanliness detection of Huoxiangzhengqi soft capsule production equipment pill press machine
[0067] Take 2 / 1000 of the contact area between the liquid medicine and the equipment to wipe the test substance with a cotton swab, add 30ml of 60% ethanol to ultrasonically dissolve and filter, wash, evaporate the filtrate to dryness, add 60% ethanol to dilute to a 1ml measuring bottle, and use it as the test solution. Separately take the contents of Huoxiangzhengqi Soft Capsules and make a 0.3mg / ml solution with 60% ethanol as a standard solution. According to the test of thin-layer chromatography (Appendix VIB of the Pharmacopoeia of the People's Republic of China, 2010 Edition), draw 10 μl of each of the above two solutions and spot them on the same thin-layer plate, spray 10% sulfuric acid ethanol solution, and heat at 105°C until the spots develop color. clear. The spots of the test solution shall not be darker than those of the standard solution.
Embodiment 3
[0068] The color development effect of embodiment 3 ethanol sulfate chromogen to different Chinese patent medicine varieties
[0069] Take Qingkailing Injection, Shujintongluo Granules, Xuanmai Ganju Buccal Tablets, Xuesaitong Dropping Pills and add water to make a 0.4 mg / ml solution. According to thin-layer chromatography (Appendix VIB, Chinese Pharmacopoeia 2010 Edition), precisely draw 10 μl of each of the above solutions, spot on the same thin-layer plate, control the spot diameter to be consistent and less than 8mm, spray 10% sulfuric acid ethanol solution, and heat at 105°C until the spots are clearly colored.
[0070] Result: the test solution of each variety shows clear spots (see attached Figure 4 )
