Steam distilled essential oil from the aerial parts of Pogostemon cablin was analyzed by gas chromatography–mass spectrometry (GC–MS). Forty one compounds were identified of which α-guaiene (20.62%) and α-bulnesene (16.18%) were major constituents. Furthermore, fractionation of the essential oil from P. cablin guided by inhibitory activity against PAF-induced platelet aggregation led to the isolation of the sesquiterpene, α-bulnesene.
