The main compounds in the leaf extract were  heptacosane, nonacosane, octacosane,  tricontane, octadecane and in the seed extract, 4-(2-2-dimethyl-6-6-methylenecyclohexyl) butanol, decahydro-8a-ethyl-1,1,4a,6-tetramethylnaphalene, octadecane, 1-chlorooctadecane and tetratetracontane were identified.
