Exploitations and prospects of natural lotus leaf bacteriostat were discussed.The main results were as follows:1、The extraction rates of crude extract, flavonoids, alkaloids and volatile oils from lotus leaves were high, and they had strong inhibition on bacteria activities but no distinct inhibition on yeast and mold.

主要研究结果如下：1、荷叶粗提物以及荷叶中的主要功能性成分黄酮、生物碱和挥发油都具有较高的提取得率，对所有供试细菌有较强的抑制作用，对霉菌和酵母菌的抑制作用相对较弱。

By identifying the obtained components by TLC, three alkaloids components were detected, among which one was nuciferine. The other two were N-Nornucirerine and O- Nornucirerine, identified by Nuclear Magnetic Resonance and Mass Spectrum.6、In order to exploit natural bacteriostat of lotus leaves, optimal extraction process and antibacterial characteristics were studied.

两者得到的化合物分别经TLC鉴别，得到3个生物碱成分，其中1个为荷叶碱，其余两个应用核磁共振和质谱等技术鉴定为N-去甲荷叶碱和0-去甲荷叶碱。6、从荷叶天然食品抑菌剂开发的角度，研究了荷叶抑菌有效成分的提取优化工艺及抑菌特性。

Thus, it hasabright prospect in the exploitation and application to extract natural bacteriostat from lotus leaves.

Antibacterial experiments results showed that extractions of bacteriostat of lotus leaves had significant antibacterial activities, and the antibacterial characteristics were stable, slightly affected by environment Conditions, such as pH value, temperature, concentration of cations. Also, the extractions exhibited strong antibacterial activities very soon.

抑菌试验结果表明，荷叶抑菌有效成分提取液具有较强的抑菌活性，且抑(来源：ABe064C论文网www.abclunwen.com)菌性能稳定，受环境条件，如pH值、温度、金属离子浓度等变化影响较小，且较短的作用时间就表现出较强的抑菌作用，因此，荷叶天然食品抑菌剂的开发具有很好的应用前景。
