Problems solved by technology

[0006] At present, Wujisan preparations on the market only have Wuji pills, Wujisan granules and Wujisan wine, and the dosage forms are relatively single.
The quality control of Wujisan preparations in the existing drug standards only includes identification and inspection items, which can no longer meet the requirements for quality control
In literature reports, only Li Ruocun et al. conducted TLC identification of ephedra, Atractylodes macrocephala, Magnolia officinalis, Angelica, and Atractylodes atractylodes in Wuji pills (Li Ruocun et al., Hunan Journal of Traditional Chinese Medicine, 1997, 13(2):43), this kind of thin-layer identification is only a qualitative quality control, and there is no quantitative quality control

Abstract

The invention discloses a finger-print quality determination method on wuji powder preparation and intermediate thereof. The finger-print quality determination method includes the following steps: quantitative wuji powder preparation or intermediate thereof is weighed, at least one of solvents of water, methyl alcohol or ethyl alcohol is used for extraction, constant volume is carried out, so as to obtain test solution; the test solution is sucked and injected into a liquid chromatograph, and high efficiency liquid chromatography and gradient elution are adopted for carrying out determination, so as to obtain the finger-print of wuji powder preparation or intermediate thereof; wherein the chromatographic conditions of the high efficiency liquid chromatography include that the filler of chromatographic column is octadecylsilane chemically bonded silica, mobile phase A is methyl alcohol, mobile phase B is phosphoric acid aqueous solution, the volume ratio of the mobile phase A and the mobile phase B is gradually increased along with time, and detection wavelength is 285-305nm. The invention has the characteristics that method is simple and stable, has high precision and good reproducibility and is easy to grasp.

Description

technical field [0001] The invention relates to a method for measuring the quality of fingerprints of traditional Chinese medicines, in particular to a method for measuring the quality of fingerprints of Wujisan preparations and intermediates thereof. Background technique [0002] At present, due to various reasons, the quality standards of traditional Chinese medicine are not perfect. Confused or even counterfeit products of traditional Chinese medicine are often seen in the market, seriously endangering people's medication safety. Therefore, it has become a consensus to strengthen the research on the quality of traditional Chinese medicine and formulate a more perfect, more accurate and more authoritative method for evaluating the quality of traditional Chinese medicine. [0003] The current standard for quality evaluation of traditional Chinese medicine is to identify and measure one or several active ingredients, active ingredients or index ingredients by means of spect...
