Chemical Composition of the Leaf Oil of<i>Psiadia altissima</i>(Compositeae)

Abstract

ABSTRACT Fresh leaves of Psiadia altissima (DC) Benth. et Hook, from Madagascar were steam distilled to produce an oil in 0.5% yield. Fifty-two compounds of the oil were characterized using GC/MS and retention indices. The hydrocarbon fraction (83%) was composed of monoterpenes and sesquiterpenes, among which β-pinene (39.7%) was the main component of this oil. Of the 25 sesquiterpenoids detected, 14 have been identified, such as T-muurolol and β-eudesmol (2.2%) and δ-cadinol (1.2%)
