Abstract

The invention discloses a method for identifying DNA (Deoxyribose Nucleic Acid) barcodes of three gentiana macrophylla medicinal materials in the pharmacopeia. Three gentian macrophylla medicinal materials in the pharmacopeia are respectively Gentiana macrophylla Pall, G.crassicaulis Duthie, and G.straminea Maxim. The identification method comprises two steps of carrying out DNA extraction and splicing obtained DNA sequences, wherein in the DNA extraction step, a good extraction effect is obtained by prolonging cracking heating time and utilizing phenol and trichloromethane, between which the volume ratio is 1:1, to remove interference of phenol and polysaccharide substances; then the obtained DNA sequences are spliced to identify gentiana macrophylla so as to obtain a good identifying effect.

Description

technical field [0001] The invention relates to a DNA barcode identification method of three Gentiana chinensis medicinal materials in the Pharmacopoeia. Background technique [0002] Gentiana chinensis is a traditional Chinese medicine commonly used in traditional Chinese medicine. It was first recorded in "Shen Nong's Materia Medica", and it was listed as a "medium grade". Traditional Chinese medicine believes that it has the effects of dispelling rheumatism, clearing damp-heat, relieving numbness and pain, and reducing asthenic heat. With the rapid development of modern medical science and technology in the research of chemical components, pharmacological effects, and clinical applications, the pharmacological effects of Gentiana chinensis have been further discovered, and clinical applications have become more and more extensive. Pharmacological research and clinical application have shown that Gentiana chinensis not only has obvious effects on anti-inflammatory and ana...
