| Abstract: | Phytochemical investigations on the leaves of Dysoxylum malabaricum and Dysoxylum beddomei result in the isolation of a number of triterpenes. Acetylation and deacetylation studies on some of the representative triterpenes show appreciable rate enhancement and increase of yield in the presence of microwave radiation. Details of isolation of triterpenes, acetylation and deacetylation procedures and their results form the subject of the paper. Triterpenes of three skeletal types namely lupane, tirucallane and cycloartane are examined. All the triterpenes examined indicate an increase of cytotoxicity with acetylation. |
