通过体外抑菌实验研究了新疆一枝蒿的水及醇提取物对10种供试菌的抑制活性,并采用试管预试法对新疆一枝蒿的抑菌活性物质进行了初步分离。结果表明:新疆一枝蒿的水提物及醇提物具有广谱的抗菌作用,无水乙醇提取物的抗菌效果最好,且新疆一枝蒿提取物对G+的抑菌效果优于G-;化学成分系统预试表明,新疆一枝蒿的活性成分可能为香豆素类、苷类和黄酮类等。
In vitro antibacterial experiment was carried out to study the inhibitory activity of water and alcohol extracts of Artemisia annua L. to 10 kinds of tested bacteria. The antibacterial active substances of Artemisia annua L. were preliminarily separated by in vitro test. The results showed that the aqueous extracts and alcohol extracts of Artemisia sphaerocephala had a broad spectrum of antibacterial activity. The antibacterial effect of ethanol extract was the best. The antibacterial effect of Artemisia scoparia extract on G + was better than that of G- The preliminary test of ingredient system shows that the active components of Artemisia annua L. may be coumarins, glycosides and flavonoids.
