Antibacterial activity and phytochemical tests of eight whole plant methanol extracts belonging to family Euphorbiaceae were evaluated. In agar well diffusion assay the diameter of inhibition zones ranged from 3-13 mm. Phyllanthus emblica showed maximum activity of 13 mm. The MIC and MBC observed were 30-140 mcg/ml and 40-160 mcg/ml, respectively. P. piscatorum and P. emblica showed the lowest MIC (30 mcg/ml), P. emblica the lowest MBC (40 mcg/ml) and thus an effective inhibitor of the tested bacteria. Alkaloids, saponins and tannins were detected in 7 out of 8 tested plants.
对大戟科8种整株植物甲醇提取物的抗菌活性和植物化学测试进行了评估。在琼脂扩散试验中,抑菌圈直径为3 - 13毫米。余甘子表现出最大活性,抑菌圈直径为13毫米。观察到的最低抑菌浓度(MIC)和最低杀菌浓度(MBC)分别为30 - 140微克/毫升和40 - 160微克/毫升。捕鱼叶下珠和余甘子表现出最低的MIC(30微克/毫升),余甘子表现出最低的MBC(40微克/毫升),因此是受试细菌的有效抑制剂。在8种受试植物中的7种中检测到了生物碱、皂苷和单宁。
