【摘要】 采用滤纸片法和平板培养法研究了芝麻特征性成分芝麻素的抗菌活性,结果表明,芝麻素对细菌的抑(杀)作用显著,且对细菌的最低抑制浓度(MIC)为0.1%;在实验浓度范围内,芝麻素对真菌基本无抑制作用。另外以过氧化值(POV)为指标研究了芝麻素对大豆色拉油和花生油的抗氧化性能,结果表明,芝麻素具有良好的抗油脂氧化活性,ω(芝麻素)=0.04%在大豆色拉油中的抗氧化活性与ω(BHT)=0.02%相当。更多还原

【Abstract】 The antimicrobial action of sesamin extracted from sesame was determined by filter paper-disk method and plate culture.The results showed that the antimicrobial action of sesamin was remarkable and the minimal inhibition concentrations(MIC)were 0.1%against bacteria, but antimicrobial action of sesamin against fungi was not obvious. Besides the antioxidation effects of sesamin in soybeansalad oil and peanut oil were studied by peroxide value(POV).The results showed that the antioxidation activity in oil was quite strongsuch as the antioxidation of sesamin in soybean salad oil by adding 0.04%ω(sesamin)was about the same as that of ω(BHT)=0.02%.更多还原
