Abstract


Phytochemical investigation on the fruit peels of Lansium domesticum Corr. had furnished one pure compound identified as lupeol (1) together with mixtures of zierone (2), cadinol (3), stigmasterol (4) and β-sitosterol (5). Structure of the pure compound was determined on the basis of spectroscopic data (1H NMR, IR, GC and GCMS) and also by comparison with literature while structures of (2) – (5) were determined based on the GC and GCMS analysis. Antioxidant test was carried out to all crude extracts (n-hexane, dichloromethane and ethyl acetate extracts) using DPPH free radical scavenging assay. The percentage values of scavenging activities showed that all crude extracts have weak antioxidant properties.
