摘要
对鲜姜、干姜、姜糖的乙醇提取物进行了抗氧化及抑菌活性研究。通过DPPH、ABTS自由基清除及还原力的测定,比较3者的抗氧化活性;通过体外抗菌实验,比较3者对金黄色葡萄球菌、大肠杆菌、绿脓杆菌及枯草芽孢杆菌的抑制作用。结果表明,3种姜产品乙醇提取物均具有一定的抗氧化活性,清除能力与浓度呈较明显的量效关系;3种姜产品对4种常见菌表现出不同的抑制作用,其抑制作用由强到弱依次为干姜、鲜姜、姜糖。本实验结果为进一步研究姜产品的抗菌药效和开发安全的食品添加剂提供了科学依据。
To study the antioxidant and antimicrobial activities of the ethanol extracts of ginger,dried ginger and candied ginger. The antioxidant activities of the three extracts were compared by detecting the DPPH and ABTS radical scavenging activity and reducing power. The antimicrobial activities of the three extracts against Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa and Bacillus subtilis were compared through antimicrobial tests. The results showed that three ginger ethanol extracts had certain antioxidant activity in a dose-dependent relationship. These extracts presented different inhibitory effects against 4 common bacteria. The order of inhibitory effect was dried ginger ginger candied ginger. These results provided a scientific basis for further researching on the antibacterial effect of ginger products and developing safe food additives.
