The content determination in the original quality standard is to detect the ferulic acid contained in Cimicifuga in the prescription, but it is found in the long-term production that using ferulic acid as the content detection index has the following shortcomings for product quality control, 1. , A large number of documents have reported that the ferulic acid solution prepared with water or methanol (ethanol) is unstable, and it is easily decomposed when exposed to light. Ferulic acid can be reduced to 20% of the relative content 2 hours after exposure to light, thereby reducing the accuracy of the test. sex
2. Taking ferulic acid as the cont

[0082] A method for detecting the quality of dragon's palm saliva, comprising the steps of:
[0083] (1) Identification of liquid in the mouth of Longzhang: Take 20ml of this product, add 2ml of ammonia test solution, shake and extract 2 times with chloroform, 10ml each time, combine the chloroform solution, evaporate to dryness, add 2ml of methanol to the residue to dissolve, and use it as a supply Test solution. Separately take 1g of Feilongzhang blood leaf and Feilongzhangxue root bark each, add 20ml of ethanol, heat to reflux for 30 minutes, filter, evaporate the filtrate to dryness, add 2ml of methanol to dissolve the residue, and use it as the reference medicinal solution. According to the test of thin layer chromatography (Appendix VI B of the Chinese Pharmacopoeia in 2005), draw 10 μl of each of the above two solutions, and place them on the same mixture of 1% potassium dihydrogen phosphate and 0.5% sodium carboxymethyl cellulose (1 : 1) On the prepared silica gel G t...

Abstract
The invention discloses a quality detection method of asiatic toddalia root gargle, comprising the following steps of: (1) identifying the asiatic toddalia root gargle; and (2) measuring the content according to a high-efficiency liquid chromatography: A, performing of a chromatograph condition and system adaptability test; B, comparison product solution preparation: precisely weighting a proper amount of isoferulic acid comparison product and preparing into the solution containing 20 mug per 1ml by using 10% ethanol; C, preparation of a test sample solution; and D, application of a measuring method: precisely absorbing 10 mul of the comparison production solution and 10 mul of the test sample solution, injecting in a liquid chromatograph for measuring, wherein every 100ml of the product contains at least 4.0mg of rhizoma cimicifugae metered by isoferulic acid. The invention has high test accuracy, can better control the quality of the medicine and ensure the medication safety, and the medicinal materials can be easily obtained.
Description
technical field [0001] The invention belongs to the field of quality control of traditional Chinese medicine preparations, in particular to a quality detection method for liquid in the mouth of a dragon's palm. Background technique [0002] Longzhangkou liquid is composed of the four medicinal materials of Feilongzhang blood root bark, Feilongzhang blood leaf, Digupi and Cimicifuga, add water and boil three times, the first time, the second time for 2 hours, the third time for 1 hour, and combine Decoction, filter, concentrate the filtrate to a clear paste with a relative density of 1.10-1.15 (60-70°C), add ethanol to make the alcohol content 70%, let it stand for 24 hours, take the supernatant, filter, and recover the filtrate Ethanol and concentrated to a clear paste with a relative density of 1.10-1.15 (60-70°C), add polysorbate 80, glycerin, mix well, boil, cool to below 40°C, add methylparaben, ethylparaben, Menthol, rose essence, coconut essence, add water to the spec...
