摘要

評估分析無患子(Sapindus mukorossi Gaertn.)、穿心蓮(Andrographis paniculata Nees.)等兩種植物之萃取液、及81.3%嘉賜銅可濕性粉劑對茄科植物細菌性斑點病菌(Xanthomonas axonopodis pv. vesicataria XVT40)之抗菌活性。結果顯示無患子（100倍，v/v）對引起茄科植物細菌性斑點病之病原菌株(Xanthomonas axonopodis pv. vesicataria XVT40)及其他Xanthomonas axonopodis pv. Citri XL1菌株的抗菌活性，顯著地較81.3%嘉賜銅(Kasugamycin and Copper Oxychloride)化學藥劑在推薦濃度下之抗菌活性爲佳；而穿心蓮之甲醇萃取液(50 mg/ml)對茄科植物細菌性斑點病之菌株(Xanthomonas axonopodis pv. vesicataria XVT40)抗菌活性則與化學藥劑之抗菌活性相近。無患子及穿心蓮萃取液對Xanthomonas axonopodis pv. vesicataria XVT40生長的最低抑制濃度(MIC)分別爲5 mg/mL及10 mg/mL。

Plant extracts from Sapindus mukorossi and Andrographis paniculata were evaluated for their antibacterial activity against Xanthomonas axonopodis pv. vesicataria XVT40 and Xanthomonas axonopodis pv. citri XL1, respectively. The results showed that the extract (100 V/V) of Sapindus mukorossi had greater antibacterial activity on the growth of Xanthomonas axonopodis pv. vesicataria XVT40 and Xanthomonas axonopodis pv. citri XL1 than that of Kasugamycin and Copper Oxychloride. The effect of methanol extract (50 mg/mL) of Andrographis paniculata on the growth of Xanthomonas axonopodis pv. vesicataria XVT40 was similar to that of Kasugamycin and Copper Oxychloride. The minimal inhibitory concentration (MIC) of plant extracts from Sapindus mukorossi and Andrographis paniculata on the gross 10 of Xanthomonas axonopodis pv. vesicataria XVT40 was 5 mg/mL and 10mg/mL, respectively.
