i摘要:以杨梅叶精油提取后的料渣为原料,对料渣的水溶性提取物进行了抗氧化分析,并将水溶性提 取物经石油醚、二氯甲烷、乙酸乙酯和正丁醇分级萃取,并测定了其抗菌能力,在此基础上将抑菌效果明显 的萃取层添加于肉糜进行防腐试验。结果表明,杨梅叶水溶性提取物在o.1~5mg/mL的浓度范围内对 DPPH自由基和羟基自由基的清除能力均随着浓度升高而提高,且达到80%以上,具有较强的 自由基清除能力。通过抑菌实验发现乙酸乙酯层和正丁醇层萃取液具有较强的抗菌性和较宽 的抗菌谱,通过对肉糜的防腐添加实验发现乙酸乙酯层萃取液优于同浓度的山梨酸钾防腐效 果,正丁醇层萃取液与同浓度的山梨酸钾防腐作用无显著差异.

The antioxidant of water- soluble extract from the debris of Myrica rubra leaves oil extracts was determined.And then,the antibacterial activity of petroleum ether,dichloromethane,ethyl acetate and n- butanols’ water- soluble extracts of residues from Myrica rubra leaves was measured and analyzed respectively. Moreover,anti- corrosion test of extract layer,which displayed obvious antibacterial effect,was evaluated by applying it to the meat. The results showed that DPPH radical scavenging activity and hydroxyl radical scavenging activity of water- soluble extract gradually elevated up to 80% between 0.1 to 5mg /mL. The antimicrobial experiment demonstrated that ethyl acetate extracts and n- butano extracts had a stronger antimicrobial performance and a wider antimicrobial spectrum. However,meat anti sepsis effect of ethyl acetate was better than potassium sorbate in the same concentration. And n- butano extracts have no significant difference with potassium sorbate.
