Embodiment 1

[0156] Embodiment 1 of the present invention: the quality detection method of barbarium medicinal material comprises the following items:

[0157] Characters: The stem is slightly square, angular, multi-branched, up to 0.2cm in diameter, purple-red, brown-yellow or yellow-green in surface, with barbed thorns on the corners, slightly swollen nodes, 2-6cm long between nodes, fibrous cross-section, yellow White, pithed or hollow; leaves alternate, with long stalks, peltate; leaves shrunken, nearly equilateral triangles after unfolding, gray-green to reddish brown, with anatropous barbs on the lower surface of the veins and petioles; Stipule sheaths wrapped on stem nodes or falling off; short spikes terminal or born in upper leaf axils, bracts round, flowers small, often shrunken or falling off; gas slightly, stems light, leaves sour.

[0158] Identification: (1) Transverse section of the stem: the epidermis is a row of sclerenchyma cells, containing reddish-brown substances; the ...

Embodiment 2

[0172] Embodiment 2 of the present invention: the quality detection method of barbaric medicinal material can only contain the following items:

[0173]Identification: (1) Transverse section of the stem: the epidermis is a row of sclerenchyma cells, containing reddish-brown substances; the cortex is thin, with 3 to 5 rows of cells; the perisheath fiber bundles in young stems form a continuous ring layer, and the old stems are cut into fragments by rays Continuous ring layer, thick cell wall, lignified; phloem old stem with bast fiber, wall thickness lignified, cambium obvious; xylem vessel large, single or in groups of 3-5; pith cell large, some hollow; old stem Most calcium oxalate clusters can be seen in the cortex, phloem, rays and pith, while the tender stems are rare or absent.

[0174] (2) Take 2 g of the medicinal material Quercetin, extract it with 80% ethanol under reflux for 1 h, filter, evaporate the filtrate to dryness, dissolve the residue in 2 mL of methanol, and...

Embodiment 3

[0184] Embodiment 3 of the present invention: the quality detection method of barbarium medicinal material can only contain the following items:

[0185] Identification: (1) Surface view of leaves: upper epidermal cells are irregularly polygonal, and anticlinal wall is nearly straight or slightly curved; below it, there are round-shaped secretory cells with a diameter of 65 μm; a few glandular hairs, with 2-8 cells in the head , short stipe; lower epidermal cells have wavy walls of anclinal cells; stomata are flat or unequal, with slightly more glandular hairs; non-glandular hairs are mostly single cells; main veins and leaf margins are sparsely hooked by multiple rows of rhomboid or rectangular cells Spiny; mesophyll cells contain calcium oxalate clusters, 17-62μm in diameter.

[0186] (2) Take 2 g of the Chinese herbal medicine, reflux and extract with 80% ethanol for 1 h, filter, evaporate the filtrate to dryness, dissolve the residue in 2 mL of methanol, and use it as the ...

Abstract

The invention discloses a method for testing quality of perfoliate knotweed medicinal material, which includes part or whole of description, identification, examination and content measurement. The aforementioned identification includes thin-layered chromatography of taking quercetin reference substance and/or quercetin-3-O-beta-D-n butyl glucuronic acid reference substance as contrast, the content measurement measures the content of quercetin in medicinal materials, which is indicated as a high performance liquid chromatography of taking quercetin as contrast and the organic facies : aqueous phase as 10-40 : 90-60. Compared to the existing technology, the invention perfects the quality detecting standard of perfoliate knotweed medicinal materials, recuperates the deficiency of the existing quality detecting technology, which makes this quality detecting technology more scientific and reasonable, and ensures its security and validity in clinical application.

Description

Technical field: [0001] The invention relates to a method for detecting the quality of barbaric medicinal materials, belonging to the technical field of quality control of medicinal materials. Background technique: [0002] Most of the traditional Chinese medicines and their preparations in my country lack strict quality standards and scientific testing methods, so it is difficult to effectively control their internal quality, cannot guarantee the safety and effectiveness of medication, and do not meet the requirements of the international pharmaceutical market, which seriously restricts the Chinese medicine industry in my country. development of. Strengthening the research on the quality control of traditional Chinese medicinal materials is a key issue in the standardization and standardization of traditional Chinese medicine. Only by carrying out scientific quality control on Chinese herbal medicines can the quality of Chinese medicine be guaranteed and the "safety, effect...
