| Abstract: | Fatty acid methyl esters of tung oil were synthesized by transesterification of tung oil and methanol with NaOH as catalyst.The AgNO3-silca gel column gradient elution method was used for the separation of reaction product to obtain methyl eleostearate.The methyl eleostearate was characterized by GC-MS,IR,UV and HPLC.The purity of the final methyl eleostearate was found to be 95%.For further study of biological activities of eleostearic acid and its glyceryl ester compound,the methyl eleostearate can be used to synthesize monoglyceride and diglyceride of eleostearic acid. |
