季铵盐改性茶皂素的合成与性能研究
Synthesis and properties of tea saponin modified with quaternary ammonium salt
摘要
Abstract
Tea saponin tertiary amine intermediate was formed by reaction between tea saponin and 3-dimethylamino propylamine. Then the intermediate further quaterized with bromoethane to produce tea saponin quaternary ammonium salt. Suitable conditions for preparation of the intermediate were identified as:using triglycol as solvent;molar ratio n (tea saponin )∶n (3 -dimethylamino propylamine )=1∶2. 5;reaction temperature 130 ℃ for 8 h. The yield of the intermediate achieves 85. 7%. Surface activity of the tea saponin quaternary ammonium salt product was measured as cmc 0. 398 g/L,andγcmc 40. 82 mN/m. Foaming power of the product is good but its foam stability is poor. Its resistance to oxidation were measured as,at a mass concentration of 1. 0 g/L,the ion ·OH and ·O2 - scavenging rate reaches 55. 4% and 66. 3% respectively. Meanwhile,the bacteria inhibitory effect of the product against E. coli,Bacillus subtilis and Staphylococcus aureus is better than that of tea saponin.关键词
