Ashitaba extract was assayed for its antibacterial activity and stability. Ashitaba extract was treated with different temperature, pH, metal iron, ultraviolet and saccharose, and its stability was also studied with Staphlococcus aureus as the indicatior strain. The results showed that Ashitaba extract had strong antibacterial activity. Antibacterial activity showed significant effect only when high temperature up to 121℃, pH 11 and metal ion calcium treatment. Ashitaba extract has better antibacterial activity and can be developed and utilized as one of natural preservative resources.%对明日叶提取物抑菌稳定性进行研究。以金黄色葡萄球菌为指示菌，分别对明日叶提取物的热稳定性、pH稳定性、金属离子稳定性、紫外线稳定性、蔗糖稳定性进行测定。结果表明，明日叶提取物对不同温度、pH值、金属离子、紫外线和蔗糖均表现出较好的稳定性，仅在121℃、pH 11或者Ca2+处理后其抑菌活性下降较快。明日叶提取物具有较好的抑菌作用，可作为一种天然防腐剂进行开发利用。
