Problems solved by technology

[0004] The solution of the present invention is to provide a HPLC-ELSD fingerprint of the main saponin components in the compound fufangteng preparation that has a better detection effect on the saponins components Atlas Inspection method, this method not only has qualitative effect (by fingerprint peak position), but also has certain quantitative effect (by correlation peak area), and can overcome the shortcoming that HPLC-UV is not high to the detection sensitivity of saponins, according to this method determined fingerprint Atlas With high repeatability, it can be used not only as an inspection and identification method for the main saponin components in the compound Fufangteng preparation, but also for the content determination of astragaloside IV and ginsenoside Rb1 in the preparation

Abstract

The invention provides a high performance liquid chromatography-evaporative light scattering detector (HPLC-ELSD) fingerprint detection method for a main saponin component of a compound wintercreeper preparation (including mixture, capsules and tablets). The fingerprint detection method of the invention comprises the steps of: preparing test solution and measuring the fingerprint under a certain chromatographic condition. Scientific tests prove that the fingerprint measured by the method has high repeatability, so that the method can be used as a method for checking and identifying the main saponin component of the compound wintercreeper preparation and can also be used for measuring astragaloside content and ginsenoside Rb1 content of the preparation.

Description

technical field [0001] The invention relates to the fingerprint of a traditional Chinese medicine compound fufangteng preparation Atlas The detection method belongs to the field of analysis and detection of compound traditional Chinese medicine preparations. Background technique [0002] The compound Fufangteng preparation is a compound preparation made from Fufangteng, astragalus, and red ginseng (or ginseng) through proper processing and extraction. Fatigue, improve the body's immunity, etc., especially suitable for patients with qi and blood deficiency, lack of energy, insomnia, dreaminess, neurasthenia, etc. The quality control method adopted at present is to carry out according to the quality standard of compound Fufangteng mixture recorded in "Chinese Pharmacopoeia" 2005 edition one. In addition to the TLC identification in the current quality standard, there is only one content determination item of thin-layer chromatography scanning, which is used to determine the ...
