Judgment method for quickly distinguishing two similar medicinal materials

Abstract

The invention relates to a judgment method for quickly distinguishing two similar medicinal materials. The method comprises the following steps: (1), precisely absorbing swertiamarin standard product solution with different volumes, analyzing by using a high performance liquid chromatograph (HPLC), drawing a standard curve and calculating a regression equation; (2), precisely absorbing gentiopicroside standard product solution with different volumes, analyzing by using the HPLC, drawing a standard curve and calculating a regression equation; (3), verifying the regression equations of the swertiamarin and the gentiopicroside respectively; (4), collecting swertia pseudochinensis hara samples; (5), testing the swertia pseudochinensis hara samples to obtain the swertiamarin content and the gentiopicroside content of the swertia pseudochinensis hara samples respectively; and (6), when the swertiamarin content is less than 1 percent and the gentiopicroside content is more than 1 percent, the swertia pseudochinensis hara samples are Swertia mussotii Franch; and when the swertiamarin content is more than 2 percent and the gentiopicroside content is less than 1 percent, the swertia pseudochinensis hara samples are Swertia franchetiana. The method is simple, convenient and quick, and can guarantee the medication correctness.

Description

technical field [0001] The invention relates to a method for judging medicinal materials, in particular to a method for quickly distinguishing two similar medicinal materials. Background technique [0002] Western Sichuan Swert Sprouts ( Sweiitia mussotii Franch ) is a plant of the Gentianaceae Swertia genus, a unique medicinal material of Tibetan medicine, recorded in the Ministry of Health of the People's Republic of China "Drug Standards Tibetan Medicine Part One" (1992 edition sixth page), its nature and flavor are: sweet, bitter , cool, rough. Functions and indications are: clearing the liver and promoting gallbladder, reducing all fevers. For jaundice hepatitis, viral hepatitis, blood disease. Qinghai Drug Standards (1992 edition, page 17) contained Chinese Swert Sprouts and Swert Sprouts in Western Sichuan ( Sweiitia Franchetiana Smith ), its nature and flavor are: bitter, cold. Functions and indications are: clearing away heat and reducing inflammation, soothin...

AI Technical Summary

Problems solved by technology

However, due to the similar biological characteristics of the two kinds of medicinal materials, Swertia brusselscens and Swertia brusselscens in western Sichuan, especially the dried medicinal materials, their shapes are almost indistinguishable, and their drug standards cannot effectively identify and distinguish the differences between the two medicinal materials, especially the lack of Differences in the morphology of dried raw materials cause confusion of medicinal materials

Due to the differences in the functions, properties and flavors of the two kinds of medicinal materials, the curative effect of the medicine is unstable and the folk medicine is not suitable for the symptoms.
