The unsaponifiable matter (USM) of n-hexane extract of C. tetragona and C. ovata revealed the presence of 32 hydrocarbons with the presence of n-tricontane as the major hydrocarbon in both species, in addition to seven steroidal components in both species. The investigation of fatty acid methyl ester (FAME) revealed the presence of 12 components in C. tetragona and 9 components in C. ovata, and a novel triterpene, namely, 28 Methyl-5α-cycloart12, 20, 24-trien-15β-Ol was isolated and identified from MeCl together with 5 known compounds.en-USArticlehttps://doi.org/10.26452/ijrps.v11iSPL4.4594
