Embodiment 1

[0053] Embodiment 1 (see figure 1 ): microscopic detection of natural copper in Chinese herbal medicines;

[0054] The specific operation steps can be carried out according to the relevant Chinese medicinal materials in the above-mentioned summary of the invention.

[0055] figure 1 It is the micrograph of the natural copper reference substance of Chinese medicinal materials. The natural copper is described in the "Pharmacopia" as follows:

[0056] Natural copper: the crystals are mostly cubes, the aggregates are dense blocks, the surface is bright light yellow, with metallic luster, some are yellowish brown or brown, without metallic luster, with streaks, green black or brownish red streaks, weight, quality Hard or slightly brittle, easy to smash, yellowish white in section with metallic luster, or brown in section, silvery white bright stars can be seen.

[0057] The micrograph can more intuitively and accurately distinguish whether it is natural copper.

Embodiment 2

[0058] Embodiment 2 (see figure 2 ): Micrograph detection of calcined natural copper in decoction pieces;

[0059] The specific operation steps can be carried out according to the content of the decoction pieces in the above-mentioned summary of the invention.

[0060] figure 2 It is the micrograph of the reference substance of calcined natural copper in decoction pieces. The calcined natural copper is described in the "Pharmacopia" as follows:

[0061] Calcined natural copper: take clean natural copper, calcined until vinegar quenched until the surface is dark brown, the luster disappears and becomes loose.

[0062]It is not easy to know whether the natural copper has been calcined to maturity only from the observation of its properties. The microscopic analysis of the natural copper after calcining can be clearly determined according to the microscopic atlas.

Embodiment 3

[0063] Embodiment 3 (see Figure 3-1 —— Figure 3-10 ): microscopic detection of Chinese patent medicine Aifu Nuangong Pills;

[0064] The specific operation steps can be carried out according to the content of the Chinese patent medicine in the above-mentioned summary of the invention.

[0065] The prescription of Aifu Nuangong Wan is:

[0066] Artemisia argyi (charcoal) 120g Cyperus cyperi (made from vinegar) 240g Evodia rutaecarpa (made from vinegar) 80g Cinnamon 20g Angelica 120g Chuanxiong 80g Paeoniae Alba (wine fried) 80g Dihuang 40g Radix Astragalus 80g Dipsacus 60g.

[0067] The micrographs of the above-mentioned herbs are as follows:

[0068] Put the powder microfilm of Aifu Nuangong Pills under a microscope for observation:

[0069] Artemisia argyi: T-shaped hair brown or burnt black, curved, stalk 2-4 cells (see Figure 3-1 ).

[0070] Rhizoma Cyperus: The secretory cells are round, containing light yellowish brown to reddish brown secretions, and the surroun...

Abstract

The invention relates to a method for analyzing the quality of Chinese medicinal materials, decoction pieces and Chinese patent drugs by utilizing micrographic atlases, which comprises the concrete steps of: 1. establishing a reference substance micrographic atlas and the database of the cell tissue thereof; 2. carrying out micrographic atlas snapping on the micrographic mount of a test object, measuring the size of the cell tissue, then contrasting the micrographic atlases and the cell tissue sizes of the test object and the reference substance by image analysis software, and automatically displaying and printing an analysis result. The invention has the advantages that the quality detection accuracy of traditional Chinese medicines can be improved, thereby enabling the quality detection work to be efficient and quick.

Description

technical field [0001] The invention relates to a method for analyzing the quality of Chinese medicinal materials, decoction pieces and Chinese patent medicines by using a micrograph. Background technique [0002] The Chinese patent discloses "Quality Control Method for Fingerprint Detection of Gardenia Medicinal Materials and Semi-finished Products of Gardenia" (Patent No.: 03146034.8), which specifically involves the fingerprint of the traditional Chinese medicine Gardenia. Make a solution with methanol as the reference substance solution, and calculate the relative retention time and peak area ratio with the retention time and peak area of ​​the chromatographic peak (S peak) of geniposide as 1. [0003] Traditional Chinese medicine fingerprints refer to the concept of forensic fingerprints, including traditional Chinese medicine DNA fingerprints, protein fingerprints and chemical fingerprints, etc.; commonly referred to as fingerprints refers to chemical fingerprints; An...
