A total of seven compounds have been isolated from the plant, which were identified as fridelin (<strong>1</strong>), ?-sitosterone (stigmast-5- en-3-one) (<strong>2</strong>), stigmasterol (<strong>3</strong>), 3,4-dimethoxy <em>cis</em>-caffeic acid (<strong>4</strong>), 3?-friedelanol (<strong>5)</strong>, ?-amyrone (<strong>6) </strong>and glyceryl tricaprate (<strong>7</strong>). The structures of the isolated compounds were elucidated by extensive NMR studies.</p> <p>DOI: <a href="http://dx.doi.org/10.3329/dujps.v13i1.21857">http://dx.doi.org/10.3329/dujps.v13i1.21857</a></p> <p>Dhaka Univ.
