Problems solved by technology

[0009] The current standard of Kunling Pills is recorded in Volume 10 of the Drug Standards of the Ministry of Health of the People's Republic of China "Preparations of Traditional Chinese Medicine". The standard does not involve any qualitative and quantitative control items for the taste of the medicine. At present, there is no fingerprint research on Kunling Pills. According to reports, fingerprints can fully characterize the integrity and complexity of traditional Chinese medicine preparations, so the inventors studied the active ingredients of Kunling Pills

Abstract

The invention provides a high-efficiency liquid-phase fingerprint detection method for Kunling Wan. The method comprises the following steps of establishment of a standard fingerprint spectrum of the Kunling Wan, determination of the fingerprint spectrum of the Kunling Wan to-be-determined, and comparison and determination of similarity. According to the invention, by trying a plurality of different elution conditions, the method finally determines the chromatographic condition for fingerprint spectrum analysis of the Kunling Wan, investigates contrast fingerprint spectrums of eight common peaks, and has the characteristics of simple process, fast speed, and good reappearance, the established standard fingerprint spectrum can satisfy relative requirements through methodology validation, applicability is strong, quality status of the product can be comprehensively reflected, and the method provides important basis for quality controlling and standard making.

Description

technical field [0001] The invention relates to a high-efficiency liquid phase fingerprint detection method for Kunling pills, belonging to the technical field of drug analysis. Background technique [0002] Kunling Pill is a compound preparation of traditional Chinese medicine. Its functions and indications are regulating menstruation and nourishing blood, removing blood stasis and promoting regeneration. It is used for irregular menstruation, more or less, abdominal pain during menstruation, cold uterus, prolonged infertility, habitual miscarriage, red and white vaginal discharge, metrorrhagia, prolonged illness, qi deficiency, kidney deficiency and low back pain. [0003] The prescription of Kunling Pills is as follows: [0004] 【prescription】 [0005] (1) Rhizoma Cyperus (made) 37g Licorice 7g Baiwei 14g Motherwort 14g Astragalus 14g Cockscomb 14g Ophiopogon japonicus 14g Schisandra 14g Rehmannia glutinosa 14g Safflower 14g Akebia 10g Atractylodes macrocephala (stir-fr...
