The pleasently smelling light yellow essential oil isolated by hydrodistillation from the leaves of Cymbopagum afronardus Stapf. (Graminea) (yield 0,4%) was anaysed by GC and GC-MS. Forty five compounds constituing about 95,9% of the oil were identified. The major constituents were 5-epiparadisol and intermedeol (40,9% toghether), 6S:7R bisabolone (39,5%) and 6R:7R-bisabolone (4m4%). The essential oil of C.afronardus was significantly different from that of C.nardus (L) Rendle. The antimicrobial activity of the oil is also reported.
