The essential oil from the leaves of Cassia arrereh Del. and Ficus thoningii Blume were analyzed using GC-MS. Eight compounds representing 100% of the essential oil from the leaves of Cassia arrereh Del, were characterized, with the major constituents as 10-methyl- Eicosane 32.50%, 2, 6, 10, 15-tetramethyl- Heptadecane 31.34 %, (R)-(-)-(2)-14-Methyl-8-hexadecen- 1-ol 12.73%. While ten compounds representing 99.99% of the essential oil from the leaves of Ficus thoningii Blume were characterized, with the major constituents as 2, 6,10, 15-tetramethyl- Heptadecane, 42.42 %, 9-methyl- Nonadecane,17.62%, Eicosane 16.17 %, , and methylsalicylate 10.58%. Although Cassia arrereh Del. and Ficus thoningii Blume belong to different families of Caleaslpiniaceae and Monaveae respectively, they both contained methylsalicylate and 2, 6,10, 15-tetramethyl- Heptadecane, 42.42 % in different proportions.
