摘要:
以金属离子催化转化人参皂苷Re生成Rg2为目标,考察金属离子在有机-水为溶剂下催化反应产物的变化情况,以及在乙醇-水体系下Fe3+催化反应产物含量随乙醇浓度、反应温度、铁离子浓度、反应时间的变化.结果表明:在乙醇-水为溶剂下催化反应产物20(S,R)-Rg2最多,催化反应条件优化结果为:乙醇体积浓度为50%,Fe3+反应浓度为0.8 mol·L-1,在40 ℃下反应12 h,产物得率为64.8%,其中20(S,R)-Rg2的质量分数为74.
Abstract:
In this paper,metal ion catalytic conversion of ginsenoside Re1 to generate Rg2 as the target,investigation of metal ions in the organic water changes as catalytic reaction solvent,and the ethanol water system under the catalysis of Fe3+ reaction product changes with ethanol concentration,reaction temperature,iron ion concentration and reaction time were also discussed.The results show that the ethanol water solvent catalytic reaction products 20(S,R)-Rg2 the most,the catalytic reaction conditions optimization results were:ethanol concentration 50%,Fe3+ concentration was 0.8 mol·L-1,the reaction at a temperature below 40 ℃,12 h,the product rate was 64.8%,and the content of 20(S,R)-Rg2 was 74.3%.The paper provided a new method for the catalytic conversion of ginsenosides to rare saponins.
