Abstract:
Objective:To further develop Gaultheria leucocarpa var. yunnanensis,anti-bacteria constituents in it were screeened. Method:The constituents were extracted by chromatographic process.The anti-bacteria test was made with regulatory method of analysis. Result and conclusion: Anti-bacteria test with extracts of water, acetic ester and n-butanol showed that 3 extracts from 22 samples had anti-Staphylococcus aureus action, and the extracts from root and stem showed the same result. 2 extracts could kill Escherichia coli and Pseudomonas aeruginosa. The lower the concentrate, the less the anti-bacteria action was. These results suggested that not only essential oil but other ingredients from G.leucocarpa var. yunnanensis have anti-bacteria activity . Anti-fungi test of the same extracts didn't indicate remarkable action.
