preparation example Construction

[0032] 1) Preparation of the test solution: after dissolving the Yajun Niuha Zhanbo granule powder with an organic solvent, ultrasonic extraction, and filtration, the test solution A is obtained;

[0033] 2) Preparation of reference solution:

[0034] Taking the six main active ingredients of Yajun Niuha Zhanbo Formula, namely Danshensu, protocatechuic acid, protocatechuic aldehyde, p-coumaric acid, rosmarinic acid and salvianolic acid B as the reference substance, use 40-70 % methanol is used as solvent to prepare mixed reference solution of different mass concentrations;

[0035] 3) Construction of fingerprint map:

[0036] Draw the test solution A and the mixed reference solution and inject it into a liquid chromatograph for high performance liquid chromatography analysis, that is, get the HPLC fingerprint of Yajunniuhazhanbo formula; establish the concentration of each substance in the mixed reference solution Or the linear relationship between the content and the peak a...

[0082] 1. Methodological investigation

[0083] 1. Examination of linear relationship

[0084] Prepare mixed reference solution according to item "2.2", inject 2 μL, 4 μL, 8 μL, 10 μL, 12 μL, 16 μL, 20 μL respectively, take the peak area as the ordinate and the injection volume of the reference substance as the horizontal coordinates, perform linear regression, draw standard curves, and fit linear equations, calculate linear range and R 2 value. The results of the linear relationship investigation are shown in Table 1. It can be seen that danshensu, protocatechuic acid, protocatechuic aldehyde, p-coumaric acid, rosmarinic acid, and salvianolic acid B are in the range of 8.0-80 μg·mL, respectively. -1 , 3.2~32 μg·mL -1 , 0.6~6.0 μg·mL -1 , 1.8~18 μg·mL -1 , 7.4~74 μg·mL -1 , 5.6~56 μg·mL -1 There is a good linear relationship with the peak area in the range, R 2 All ...

Abstract

The invention discloses an HPLC (High Performance Liquid Chromatography) fingerprint spectrum construction method and a detection method of a Yaohuahuangboo prescription. According to the present invention, the HPLC fingerprint spectrum and the multi-index content determination are combined for the first time, and the qualitative identification and the content determination are performed on the multi-batch Yaohuahuangboo particles so as to provide the good monitoring and evaluation of the quality of the Yaohuahuangboo particles and the guidance of the standardized production, such that the high application value is provided; a research clue is provided for establishing a quality standard of the Yaohuahuangboo particles with multiple components and multiple indexes, and a solid foundation is laid for deep development of the Yaohuahuangboo particles. The fingerprint spectrum prepared by the method disclosed by the invention not only can be used for qualitatively and quantitatively detecting the Yaohuahuangboo granules at the same time, but also can be used for qualitatively and quantitatively detecting dosage forms such as Yaohuahuahuangboo pills and extractum.

Description

technical field [0001] The invention belongs to the technical field of chemical detection, and in particular relates to a method for constructing an HPLC fingerprint of Yajun Niu Ha Zhanbo formula and a detection method. Background technique [0002] Yazong Niu Ha Zhanbo is a traditional prescription of Dai medicine. It is contained in the ancient Dai medical classics "Dang Ha Ya Zhao Shu Wan Na". It has a history of more than 1300 years. , Coix root, licorice, has the effect of clearing heat and diuretic fossils, used for the treatment of acute and chronic nephritis, pyelitis, urinary tract infection, kidney, ureter, bladder stones. Xishuangbanna Dai Medical Hospital developed a medical institution preparation "Wulin Fossil Capsule" (Dian Yao Zhi Zi (Z) 20082254K) on the basis of this traditional prescription for clinical application [0003] For 20 years, it has proven efficacy and high safety in the treatment of urinary tract infections and stones. At the same time, the...
