| Abstract: | Rosolic acid reacted with acetic anhydride to synthesize rosolic acid-triacelate ester tri(4-acetoxy) phenyl methane] under reflux condition.The product was characterized by means of UV-Vis,infrared spectroscopy and 1HNMR(nuclear magnetic resonance).An ultraviolet-visible absorption spectroscopy way was employed to optimize the reaction conditions.Influences of reaction time,solvent proportion,and reactant ratio on the reaction were discussed in detail.The experimental results showed that yield of the product was 54.6% under the optimum conditions. |
