To compare the anti-bacterial activity of the extracts from different organs and the leaves from different locations of Sargentodoxa cuneata, and to provide the basis for the exploitation of the leaves.
The leaves was distilled with 60% acetone and the water phase after the extraction with petroleum ether and chroloform was used in the test. The Staphylococcus cureus and Pseudononas aerujinosa were used as the experimental strain. The minimal inhibition concentration was calculated using agar plate dilution method. The minimal bacterialcidal concentration was calculated using tube dilution method.
The anti-bacterial activity of the extraction of S. cuneata from leaves was the highest. That from slices took the second place and the third was that from old stems. That from twins was the lowest. The sequence of the anti-bacterial activity of S. cuneata from different locations was Daleishan > Bianshanzu > Huadingshan > Changhua > Kuochangshan.
The anti-bacterial activity of the extraction from the leaves of S. cuneata can be detected and the foreground of the exploitation and utilization is good.
比较大血藤不同器官及不同产地叶片提取物的抗菌活性，为大血藤叶片的开发利用提供依据。
用60%丙酮对叶片进行蒸馏，取石油醚和氯仿萃取后的水相进行试验。以金黄色葡萄球菌和铜绿假单胞菌为试验菌株。采用琼脂平板稀释法计算最低抑菌浓度。采用试管稀释法计算最低杀菌浓度。
大血藤叶片提取物的抗菌活性最高，切片提取物次之，老茎提取物居第三，藤梢提取物最低。不同产地大血藤抗菌活性顺序为：凤阳山＞百山祖＞华顶山＞昌化＞括苍山。
大血藤叶片提取物具有抗菌活性，开发利用前景良好。
