【摘要】：本试验旨在研究植物精油与丁酸钠的体外协同抑菌效果。采用牛津杯法,测定肉桂醛、百里香酚和香兰素对于4种细菌(大肠杆菌、沙门氏菌、产气荚膜梭菌、乳酸菌)的抑菌效果。并将单方和复合植物精油分别与丁酸钠复配,测定其抑菌效果。结果表明:3种植物精油均对大肠杆菌、沙门氏菌、产气荚膜梭菌有明显抑制作用,但对乳酸菌无抑制作用,在相同浓度下,抑菌效果为肉桂醛香兰素百里香酚。肉桂醛与香兰素复合植物精油抑菌效果优于单方植物精油,当肉桂醛与香兰素的质量比为6∶1时抑菌效果最佳。丁酸钠没有显示出抑菌作用,但丁酸钠与植物精油复合可明显降低植物精油的使用量。综上所述,不同植物精油的复合具有协同作用,植物精油和丁酸钠之间也存在着协同作用。
[Abstract]:The purpose of this experiment was to study the synergistic bacteriostatic effect of plant essential oil and sodium butyrate in vitro. The inhibitory effects of cinnamaldehyde, thymol and vanillin on four bacteria (E. coli, Salmonella, Clostridium perfringens and Lactobacillus) were determined by Oxford Cup method. Single and compound essential oils were mixed with sodium butyrate to determine their bacteriostatic effect. The results showed that the three plant essential oils had obvious inhibitory effect on Escherichia coli, Salmonella and Clostridium perfringens, but had no inhibitory effect on lactic acid bacteria. At the same concentration, the bacteriostatic effect was cinnamaldehyde vanillin thymol. The bacteriostatic effect of cinnamaldehyde and vanillin compound essential oil was better than that of monopodium essential oil. When the mass ratio of cinnamaldehyde to vanillin was 6:1, the bacteriostatic effect was the best. Sodium butyrate did not show bacteriostatic effect. To sum up, the complex of different plant essential oils has synergistic effects, and there is also a synergistic effect between plant essential oils and sodium butyrate.
