摘　　要：以4种细菌,大肠埃希菌(Escherichia coli)、金黄色葡萄球菌(Staphylococcus aureus Rosenbach)、枯草芽孢杆菌(Bacillus subtilis)、铜绿假单胞菌(Pseudomonas aeruginosa)和4种真菌,白色念珠菌(Candida albicans)、番木瓜炭疽菌(Colletotrichum papayae P.Henn)、芒果炭疽菌(Colletotrichum gloeosporioides)、芒果蒂腐菌(Dothiorella dominicana)作为供试菌,用圆形纸片法对海南2种江蓠(海南江蓠和细基江蓠)的乙醇、石油醚、乙酸乙酯、正丁醇提取物进行抗菌活性比较研究。结果表明:2种江蓠提取物均具有较为广谱的抗菌能力,且不同提取物的抗菌活性物质、抗菌活性和范围不同,海南江蓠的抗菌效果优于细基江蓠。Four kinds of bacterium（Escherichia coli,Staphylococcus aureus Rosenbach,Bacillus subtilis,Pseudomonas aeruginosa）and four kinds of fungus（Candida albicans,Colletotrichum papayae P.Henn,Colletotrichum gloeosporioides,Dothiorella dominicana）were used as the test bacteria,the antibacterial activities of extract of ethanol,petroleum ether,ethyl acetate,n-butanol from two Hainan Gracilaria（Gracilaria hainanensis,Gracilaria tenuistipctata）were studied by circular paper method.Results showed that,two kinds of Gracilariaextract both had more broad-spectrum antibacterial activities,and antibacterial active substances,antibacterial activities and range of different extract were different,the antibacterial efficiency of Gracilaria hainanensis was better than that of Gracilaria tenuistipctata.
