Problems solved by technology

[0005] For this reason, what the present invention is to solve is that the single detection index of the existing Yindan Pinggan Capsule cannot detect and control its quality as a whole, and the joint detection of multiple detection indexes is time-consuming and laborious, and it is difficult to be widely used in production practice. To solve the technical problems, a detection method for the fingerprint of the pharmaceutical preparation for the treatment of hepatitis is proposed

Abstract

The invention relates to a detection method for a fingerprint spectrum of a medicinal preparation treating hepatitis. In the detection method, through optimization selection of a No.11 peak of baicalin as an internal reference peak of a fingerprint spectrum, retention time of characteristic common peaks: a No.3 peak of chlorogenic acid, a No.4 peak of gentiopicroside, a No.5 peak of paeoniflorin, a No.6 peak of liquiritin, a No.8 peak of ferulic acid and the like of a yindan pinggan capsule is determined, the yindan pinggan capsule can be detected comprehensively and rapidly, which facilitates comprehensive quality detection and whole quality control, and therefore safety and stability of medicine usage is raised.

Description

technical field [0001] The invention belongs to the field of drug analysis, in particular to a method for detecting the fingerprint of a drug preparation for treating hepatitis. Background technique [0002] Hepatitis is a common infectious disease, generally divided into icteric hepatitis and chronic hepatitis. The raw materials of Yindan Pinggan Capsules are Yinchen, Gentian, Scutellaria, Pig Gall Powder, Gardenia, Radix Paeoniae Alba, Angelica, and Licorice. Treatment of hepatitis and chronic hepatitis. Chinese patent document CN1275381A discloses the raw material composition and preparation method of Yindan Pinggan Capsules. Chinese patent document CN101987121B discloses a detection method of Yindan Pinggan Capsules, which is to measure the content of baicalin in the pharmaceutical composition for treating hepatitis by HPLC method, and also discloses the TLC identification method of Yinchen, hyodeoxychole The quality of Yindan Pinggan Capsules was controlled by the TL...
