| 摘 要： | 对蜂胶提取物抑菌性能进行研究，同时以蜡样芽孢杆菌为指示菌研究蜂胶提取物抑菌成分的稳定性。结果表明：蜂胶提取物具有较强的抑菌活性，对热处理、pH 值、紫外线、金属离子均具有较好的稳定性，仅在121℃或pH10 处理后其抑菌活性才明显下降。

| Abstract: | The ethanol extract from propolis obtained by hot reflux extraction was assayed for its antimicrobial activity, and its stability was also studied with Bacillus cereus as the indicator strain. The results showed that the extract had very strong antimicrobial activity and was very stable to temperature, pH value, ultraviolet and metal ions. After thermal treatment at 121℃ or alkaline treatment at pH 10, the antimicrobial activity of the extract showed a notable descent. |
