Embodiment

[0041] A detection method for antiviral oral liquid. The method uses high performance liquid chromatography to detect the content of (R, S)-Gao Yichun. The method specifically includes the following steps:

[0042] Instruments and reagents: Shimadzu LC-20A high performance liquid chromatograph, quaternary low pressure pump, UV detector, YMC C-18 column (4.6mm×25cm, 5μm).

[0043] Reagents and reagents: (R, S)-Gao Yichun reference substance (China Institute for the Control of Pharmaceutical and Biological Products, batch number: 111753-201103);

[0044] Antiviral oral liquid (Hangzhou Laotongjun Pharmaceutical Co., Ltd., batch number: 20121201, 20121202, 20121203);

[0045] Acetonitrile (chromatographically pure), methanol (chromatographically pure), water (purified water), other reagents are of analytical grade.

[0046] Chromatographic conditions: using YMC C-18 column (4.6mm×25cm, 5μm), mobile phase: methanol as mobile phase A, 0.01% phosphoric acid solution as mobile phase B, gradie...

Abstract

The invention discloses a detection method of anti-viral oral liquid. According to the method, the content of (R,S)-goitrin is detected by a high performance liquid chromatography. By adopting the detection method, the content of a main constituent of the anti-viral oral liquid can be effectively detected; the defects of the traditional detection method are compensated; the quality and the curative effect of the product are improved; and monitoring of an administrative department on the product is also facilitated.

Description

technical field [0001] The invention relates to a detection method of an antiviral oral liquid, belonging to the technical field of pharmacy. Background technique [0002] Antiviral Oral Liquid is a drug recorded in the drug standards. It is an oral solution made of nine traditional Chinese medicines such as Radix Isatidis, Forsythia, Anemarrhena, Reed Rhizome, Patchouli, Rehmannia, Shichangpu, Curcuma, and Gypsum. It has the functions of clearing away heat and dampness, cooling blood and detoxifying, and is used for wind-heat cold, influenza and other viral infections. The detection method of existing antiviral oral liquid is too simple, mainly is the qualitative inspection to Radix Radix Radix, does not have the quantitative detection of the content of its main drug component, makes the detection method of existing antiviral oral liquid not perfect enough, detects The results are not accurate enough, affecting the efficacy of the drug. In order to further ensure the qual...
