The Screening of the Bacteriostatic Activities of Artemisia rubripes Nakai Extractives
摘要
Abstract
[ Objective] The aim was to study the bacteriostasis of the ethanol extracts from Hunan A. Rubripes branches and leaves. [ Methods] The ethanol extractives were extracted and separated from A. Rubripes branches and leaves by different solvents, and petroleum ether extracts, ethyl acetate extracts and aqueous solution were obtained. Then, each fraction was analyzed qualitatively using HPLC, and their bacte-riostatic activities on Escherichia coli, Bacillus sublilis and Staphylococcus aureus were studied using Oxford cup method. [ Result ] The bacteri-ostatic effects of the ethanol extracts on E. Coli and B. Subulis were obvious, and the bacteriostatic effects of the ethyl acetate extracts on the above three test organisms were better; however, petroleum ether extracts and aqueous solution had no obvious bacteriostatic effect on the a-bove three test organisms. [Conclusion] The major antibacterium active constituents in A. Rubripes were the semi-polar compounds, but polar compounds in water solution had synergetic effect for these antibacterium activities.关键词
