    Abstract: The experimental design is divided into two parts: chemical analysis and bioactive assay. One
    antioxidant lupeol (4) and one inhibition of tyrosinase pheophorbide a methyl ester (7) were identified in
    Leucaena leucocephala. Both showed effective 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging
    activity compared with vitamin C, and mushroom tyrosinase compared with kojic acid. These results
    suggest that these constituents of L. leucocephala act as natural antioxidants and play a potential role
    in prevention of pigmentation
