Problems solved by technology

Because Xuanmai Ganju Capsules also contain a variety of chemical components of the four medicinal materials of Radix Scrophulariae, Ophiopogon japonicus, Licorice and Platycodon grandiflorum, including: iridoid compound harpagoside, phenylpropanoid compound cinnamic acid, flavonoid component licorice Glycyrrhizic acid, saponins, crude saponins ophioposide Ra, platycodon saponin D and other parent nuclei have similar structures and properties, and often interfere with each other in qualitative and quantitative detection. It is necessary to use HPLC to accurately separate the target substance from other impurities. Effective separation and quantitative analysis are more difficult, and the quality control of prescription preparations is even more difficult
[0003] Existing technology "Chinese Pharmacopoeia" 2015 edition, Guo Wenting, etc. [RP-HPLC gradient elution method to determine the content of harpagoside and cinnamic acid in Xuanmai Ganju capsules, Chinese medicinal materials, Volume 31, Issue 8, August 2008], Jiang Huake [Determination of Glycyrrhizic Acid Content in Xuanmai Ganju Granules by High Performance Liquid Chromatography, Zhongnan Pharmaceutical Sciences, Volume 10, Issue 2, February 2012] or Xu Xiuying et al. The content of asapenoside A, Chinese Pharmacy, Vol. 2l, No. 39, 2010] and other HPLC detection methods only detect the specific components of specific medicinal materials in Xuanmai Ganju capsules, but cannot effectively control the prescription of Xuanmai Ganju. Accurate qualitative and quantitative analysis of the active ingredients of multi-flavored medicinal materials in preparations
The HPLC detection method introduced by Zhang Ping, Guo Yadong, etc. [RP-HPLC Determination of Liquiritin, Glycyrrhizic Acid, Harpagoside and Cinnamic Acid in Xuanmai Ganju Granules, Journal of Pharmaceutical Analysis, 2008, 28 (5 )] Although the active ingredients liquiritin, glycyrrhizic acid, harpagoside and cinnamic acid were detected by the dual-wavelength detection method, the active ingredients platycodon saponin D and radix radix There are miscellaneous peaks wrapped around the glycoside peak, and tailing phenomenon occurs, and the entire baseline is too high, and the interference is serious, so it is impossible to conduct accurate qualitative and quantitative analysis of the active ingredients in the prescription preparation of Xuanmai Ganju

Abstract

The invention provides a pharmaceutical composition detecting method. A pharmaceutical composition is a composition which comprises a Scrophularia sinensis extract, an Ophiopogon japonicus extract, alicorice extract or a platycodon extract, and is detected by using high performance liquid chromatography. According to the liquid chromatographic detection conditions, a chromatography column is octadecylsilane-bonded silica gel as a filler; mobile phase A is a phosphoric acid solution, and mobile phase B is acetonitrile; and gradient elution and dual wavelength switching are used for detection.The method is fast, efficient, stable, accurate and effective, and can simultaneously quickly and effectively detect multiple index components of the pharmaceutical composition.

Description

technical field [0001] The invention relates to the field of drug detection, in particular to a detection method of a drug composition. Background technique [0002] Xuanmai Ganju capsules, granules and other prescription preparations are recorded in the first part of the "Chinese Pharmacopoeia" 2015 edition. It has the functions of clearing heat and nourishing yin, eliminating phlegm and relieving sore throat. It is used for hyperactivity of fire due to yin deficiency, rising of asthenic fire, dry mouth and nose, and sore throat. Because Xuanmai Ganju Capsules also contain a variety of chemical components of the four medicinal materials of Radix Scrophulariae, Ophiopogon japonicus, Licorice and Platycodon grandiflorum, including: iridoid compound harpagoside, phenylpropanoid compound cinnamic acid, flavonoid component licorice Glycyrrhizic acid, saponins, crude saponins ophioposide Ra, platycodon saponin D and other parent nuclei have similar structures and properties, and...
