| 摘 要： | 初步研究了油茶总皂甙对几种常见的食品腐败菌和植物病原真菌的抑菌活性,结果表明,油茶总皂甙在高浓度下对啤酒酵母、金黄色葡萄球菌和枯草芽孢杆菌抑菌作用较强,其MIC值分别为12.5、12.5和3.2mg/ml,低浓度只起到一定程度的抑制作用;对三种霉菌桔青霉、黑曲霉、米曲霉抑制作用较弱;油茶总皂甙对六种植物病原真菌抑菌活性强弱表现出较强的选择性,对小麦纹枯病菌和棉花黄萎病菌的抑菌活性较强,EC50分别为:0.081、0.169mg/ml,且抑制活性同浓度呈正相关。

| Abstract: | The antimicrobial actions of tea saponin from the Camellia Oleifera were studied in vitro. The results showed that the high concentration of crude saponin has relatively strong inhibition effect to Staphylocooccus aureus, Bacillus subtilis and Saccharomyces cerevisiate respectively, especially to Saccharomyces cerevisiate. Its MIC is 3.2mg/ml. It had no abvious action to Aspergillus fungi. It had selectivity inhibition effect to different plant pathogeny fungus. And its effieacy correlated to teasaponins'c oncentration. |
