Abstract
Three new dammarane-type triterpenoids, namely elliptaglin A-C (1–3) were isolated from the stem bark of Aglaia elliptica (C.DC.) Blume along with three known derivatives, namely (20S)-hydroxydammar-24-en-3-on (4), cabralealactone (5), and E-25-hydroperoxydammar-23-en-20-ol-3-one (6). Subsequently, their chemical structures were determined using HR-ESI-MS, FTIR, 1D and 2D-NMR spectroscopic analysis as well as comparison with previous studies. The cytotoxicity activities of the isolated compounds against MCF-7 breast cancer and B16-F10 melanoma cell lines were then tested using PrestoBlue reagent. The analysis results showed that elliptaglin B (2) had the strongest activity against both cell lines with IC50 values of 60.98 and 51.83 µM, respectively.
