Abstrakt: In this recent investigation, the focus centred on exploring the potential phytoconstituents within the bark of Dysoxylum malabaricum . A profiling strategy employing LC-HRMS (Liquid Chromatography-High Resolution Mass Spectrometry) was implemented for the rapid identification of compounds from the bark extract. The crude extract underwent fractionation, resulting in the isolation of four previously known compounds ( 1-4 ) and a novel cycloartane triterpenoid named Mahamanalactone A ( 5 ). Compound 5 represents a cycloartane triterpenoid with a modified ring-A, featuring £-caprolactone fusion at positions 4 and 5, distinguishing it from other reported compounds where £-caprolactone is typically fused at positions 3 and 4. Cytotoxicity assessment revealed that the newly identified compound 5 exhibited a moderate cytotoxic profile (IC 50 29 to 78 µM) against a panel of cancer cell lines.
