Abstract
A new asymmetrical ester,6-L-ascorbyl trans-β-alkoxycarbonylacrylate,containing α,β-unsaturated carbonyl group structure was prepared via esterification. The antimicrobial activity of 6-L-ascorbyl trans-β-alkoxycar-bonylacrylate was studied. Results showed that 53.45% yield could be obtained. The minimum inhibition concentration and inhibition rate of 6-L-ascorbyl trans-β-alkoxycarbonylacrylate to Escherichia coli,Bacillus subtilis,Saccharo-myces cerevisiae was 1.0 g/L,88. 83% ; 0. 75 g/L,80. 47% ; 0. 75 g/L,82. 12% respectively. Its antimicrobial activity was much better than sodium benzoate and postassium benzoate,besides the antimicrobial activity did not changed obviously under heat treatment. It was also seen that 6-L-ascorbyl trans-β-alkoxycarbonylacrylate had strong antimicrobial effects for bacteria and yeasts. It is worth the exploration of further development and application.关键词
