[0278] Example 2 Study on Experimental Methodology of Bitter Almond High Performance Liquid Chromatography Identification and Content Determination

[0279] The identification of bitter almonds in the current quality standard uses thin-layer chromatography, but the color of the thin-layer spots is not obvious. It is not obvious, so in the present invention, high performance liquid chromatography is adopted to identify bitter almond components in Qingke Pingchuan granules and carry out content determination. The detection wavelength, mobile phase, chromatographic column, theoretical plate number, and sample processing method in the detection method etc. to carry out screening research and methodological verification, and the test data show that the method is scientific and stable, and can achieve the purpose of controlling product quality.

[0280] According to the 2015 edition of "Chinese Pharmacopoeia", Appendix XVIII A, the guidelines for the verification of analytical metho...

Abstract

The invention provides a detection method for cough-suppressing and panting-calming particles. The particles comprise raw materials of herba houttuyniae and bitter apricot seeds. The method comprises detecting herba houttuyniae in the particles through thin layer chromatography, and detecting bitter apricot seeds in the particles through high performance liquid chromatography and measuring the amygdalin content. The detection method is good in repeatability and specificity, conforms to the accurate, simple, sensitive and fast principle, and can effectively control the quality of the particles. According to the method, the quality standard of cough-suppressing and panting-calming particles is stricter, the detection items are comprehensive, and the quality control system is complete and scientific.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine detection, and relates to a detection method of traditional Chinese medicine preparations, in particular to a detection method of Qingke Pingchuan Granules. Background technique [0002] Qingke Pingchuan Granule is a compound preparation of traditional Chinese medicine. The drug approval number is Z20040047, and the current quality standard number is YBZ02472004-2009Z. The contents of the standard mainly include: [0003] prescription: [0004] [0005] Preparation method: the above ten flavors, Chuan Fritillaria are crushed into coarse powder, according to the percolation method (Appendix IO of Chinese Pharmacopoeia 2005 Edition) under the item of extract and extract, use 70% ethanol as solvent, and soak for 48 hours After percolation, collect about 1000ml of filtrate, recover ethanol until it has no alcohol smell, and set aside; steam distill Houttuynia cordata for 3 hou...
