For Qualitative detection The fractions used to method of the thin layer chromatography (TLC) when a solvent phase were Benzene and Ethyl acetate (1:1). Fractions were also analyzed to measure the amount of terpenoides. The major constituents of the Terpenoids in study showed Decane 100%, Cyclodecane 61.23%, Dodecane 56.78%, Butanoicacid 50.37% , Cyclohexasiloxan 40.14%, Phenonemethoxynaphthoquinone 34.39%, 1,4-Naphthoquinone 19.87%, 2- methylbutanoate 17.6% , N-Aethylpiperidin 17.59%.
