The ethanol extract of Decalepis hamiltonii roots was subjected to antioxidant activity-guided fractionation by repeated silica gel column chromatography to get a pure antioxidant compound which was subjected to extensive analysis by UV, IR, LC-MS, and 2D HMQC NMR. The spectral data of the isolated compound was analyzed, and its structure was elucidated as decalpoline, a novel antioxidant compound not reported so far. Decalpoline exhibited multiple antioxidant properties like DPPH scavenging activity, superoxide radical scavenging activity, lipid peroxidation inhibitory activity, metal chelating and total reducing activity.
