Cytotoxic activity of betulinic acid and ursolic acid againts T47D breast cancer cells

<p><em><span>Uncaria nervosa</span></em><span> Elmer is an Indonesian herbal plant that is traditionally used for breast cancer. The results of phytochemical screening contained alkaloids, flavonoids, and terpenoids in the ethanol extract of this plant. Based on literature searches, reports regarding the bioactive compounds responsible for breast cancer have not been found. </span><span>This study aims to determine the metabolite profiling of ethanol extract, the isolation, characterization of bioactive compounds, and their bioactivity in T47D breast cancer cells. The ethanol extract of <em>Uncaria nervosa</em> Elmer leaves contains nine compounds consisting of alkaloids, terpenoids, and fatty acid. The bioactive compounds that were successfully isolated were betulinic acid, and ursolic acid, with IC50 values of ˃100 and 14,70&plusmn;4,50 &micro;g/ml, respectively.</span></p>
