and fruit and leaf were investigated for their ability to inhibit spp. growth. Extracts of both spp. displayed potent growth inhibitory properties against all spp. tested in disc diffusion and liquid diffusion assays. In general, extracts were more potent inhibitors of spp. growth, and the fruit extracts were generally better than the corresponding leaf extracts. The methanolic fruit extract was a particularly potent inhibitor of all spp. growth, with MIC values as low as 87 µg/mL. The aqueous and ethyl acetate fruit extracts were similarly potent inhibitors of spp. growth, albeit with slightly higher MIC values. Several other spp. extracts also were potent bacterial growth inhibitors, albeit with MIC values generally >1000 µg/mL. The most potent fruit extracts were nontoxic in the bioassay, with LC values substantially >1000 µg/mL. The potent bacterial growth inhibitory activity and lack of toxicity of the fruit extracts indicate their potential as natural fish and seafood preservatives.
对果实和叶子抑制某菌属生长的能力进行了研究。两种提取物在纸片扩散法和液体扩散法试验中,均对所有受试的该菌属表现出强大的生长抑制特性。总体而言,提取物是该菌属生长的更强抑制剂,且果实提取物通常优于相应的叶子提取物。甲醇果实提取物是所有该菌属生长的特别强效抑制剂,最低抑菌浓度(MIC)值低至87微克/毫升。水相和乙酸乙酯果实提取物同样是该菌属生长的强效抑制剂,尽管MIC值略高。其他几种提取物也是强效的细菌生长抑制剂,不过MIC值通常>1000微克/毫升。最有效的果实提取物在生物测定中无毒,致死浓度(LC)值远>1000微克/毫升。果实提取物强大的细菌生长抑制活性和无毒性表明它们有作为天然鱼类和海鲜防腐剂的潜力。
