Problems solved by technology

[0005] According to the current Chinese Pharmacopoeia standards, three methods are used to quantitatively determine the main components of the Sanwei prescription in Shuanghuanglian oral liquid, chlorogenic acid, baicalin and forsythin, which are cumbersome and time-consuming
On the other hand, the current standard does not effectively control the overall fingerprint
The simultaneous quantification of 11 components in Shuanghuanglian preparations has been reported in the literature [Bian Tingting. Journal of Pharmaceutical Analysis, 2012,32(1):52-56.; Yang D.Talanta,2011,85(2):885-890.] , which greatly simplifies the detection process,

Abstract

The invention relates to a quantitative fingerprint quality monitoring technology for Shuanghuanglian oral liquid, and belongs to the technical field of compound quality analysis. A dual-wavelength quantitative fingerprint spectrum quality control method is established on the basis of a high performance liquid chromatography-ultraviolet detection technology, fingerprint spectrum monitoring of the Shuanghuanglian oral liquid is achieved through one-time analysis, content determination of three index components of chlorogenic acid, baicalin and forsythin is achieved at the same time, and one-standard multi-determination amount of neochlorogenic acid and cryptochlorogenic acid is achieved. According to the method, fingerprint spectrum and quantitative detection are simultaneously realized in one-time analysis, the quality of the Shuanghuanglian oral liquid can be more comprehensively and accurately evaluated, the Shuanghuanglian oral liquid of different manufacturers can be distinguished, meanwhile, the detection time is shortened to the greatest extent, and the resource consumption is reduced.

Description

technical field [0001] The invention relates to a quantitative fingerprint quality monitoring technology of Shuanghuanglian oral liquid, which belongs to the technical field of compound prescription quality analysis. [0002] technical background [0003] Shuanghuanglian Oral Liquid is composed of Scutellaria baicalensis, honeysuckle and forsythia according to the prescription dosage of 1:1:2. Forsythia is the dried fruit of Forsythiasuspensa (Thub.) Vahl, a plant of Oleaceae. It is the main component type, and has the effects of clearing away heat and detoxification, reducing swelling and dispelling stagnation [Xia Wei. Chinese Modern Traditional Chinese Medicine, 2016, 18(12): 1670-1674]; honeysuckle is the dry flower bud or the first bloom of Lonicera japonica Thunb. Scutellaria baicalensis, with chlorogenic acid as the main active substance, is commonly used clinically for antibacterial, antiviral, anti-inflammatory, etc. The dried root of Scutellaria baicalensis Georgi...
