目的 :对传统上用于治疗作用的 6个不同品种芦荟的蒽甙 (蒽衍生物 )进行了提取 ,并进行了抑菌作用的比较研究。方法 :琼脂扩散法。结果 :从叶皮中提取的有效成分表现出不同程度的抑菌活性 ,而叶肉提取物则几乎没有抑菌效果。其中 ,龙山芦荟 ,皂质芦荟和木立芦荟的叶皮提取物对革兰阴性菌和革兰阳性菌均具有较强的抑菌能力 ,而且这种抑菌活性与蒽醌成分呈正相关性。
Objective: To compare the antibacterial activity of the aphid (american derivatives) of six different aloe varieties traditionally used for therapeutic purposes. Method: Agar diffusion method. Results : The active ingredients extracted from the leaf bark showed different degrees of antibacterial activity, while the mesophyll extract had almost no antibacterial effect. Among them, the leaf extracts of Aloe vera, Aloe barbadensis, and Aloe arborescens have strong antibacterial activity against gram-negative bacteria and gram-positive bacteria, and this antibacterial activity is positively correlated with that of alfalfa.
