红豆杉纯露的抑菌性能研究

Study on Bacteriostatic Properties of Pure Dew of Taxus chinensis

通过水蒸气蒸馏,从新鲜红豆杉枝叶中按一定比例提取纯露,并以纯露为原料制备空气清新剂喷雾。采用白色念珠菌(真菌)、金黄色葡萄球菌(革兰氏阳性菌)、大肠杆菌(革兰氏阴性菌)作为实验的指示菌,研究了红豆杉喷雾的体外抑菌作用,评估其抑菌性能。结果表明红豆杉喷雾对真菌与细菌均有一定的抑菌作用,纯露的短期杀菌效能低于75%酒精,但长效抑菌效能优于75%酒精。上述结果,为开发红豆杉消毒产品以及进一步探索其在空气清新剂上的应用价值提供依据。

Using steam distillation, pure dew was extracted from fresh Taxus chinensis branches and leaves, and an air freshener was prepared by pure dew. Candida albicans (fungi), Staphylococcus aureus (Gram-positive bacteria), and Escherichia coli (Gram-negative bacteria) were used as the indicator bacteria to study the bacteriostatic effect of Taxus chinensis spray in vitro and to evaluate its bacteriostatic performance. The results showed that Taxus sprays could inhibit bacteria and fungi. It was found that the short-term bactericidal efficacy was lower than 75% alcohol, while the long-term bacteriostatic efficacy was better than 75% alcohol. It provided a basis for the development of Taxus chinensis disinfection products and the further exploration of the air freshener.
