Abstract

The invention relates herba dracocephalum heterophylli volatile oil possessing the bacteriostatic and germicidal action and its application. The method adopts steam distillation to extract the herba dracocephalum heterophylli volatile oil and adopts gas-chromatography/mass spectra to analysis the volatile oil, identifying the 83 components and 89.83% total content. The volatile oil can kill and suppress the staphylococcus, streptococcus, gonococcus, enterobacter, Escherichia, salmonella, shigella, pseudomonas, bacillus, oidiomycin, cryptococcus, aspergillus, penicillium, mucor, epidermophytin, micromonospora, trichophyton and other bacteriums. The herba dracocephalum heterophylli volatile oil is used for foodstuffs, drugs, health products, cosmetic products and other industries.

Description

technical field [0001] The present invention relates to the volatile oil of Tibetan medicine Chrysanthemum heterophyllum with bacteriostatic and / or bactericidal effect and its application in preparing products with bacteriostatic and / or bactericidal effect. Background technique [0002] Infectious diseases caused by pathogenic microorganisms seriously endanger human health and cause huge social and economic losses. For infectious diseases caused by bacteria, the effective application of antibiotics is to use antibiotics, but the increasing bacterial resistance caused by the extensive use of antibiotics has become one of the most common problems in the world. In particular, the drug resistance rate of Staphylococcus aureus has reached more than 90%. At the same time, the intestinal flora disorder caused by it also aggravates the primary infection. Finding and developing new drugs with antibacterial activity from natural medicines has attracted increasing attention. The emerg...
