Chemical Composition of Hypericum laricifolium Juss. Essential Oil Collected from merida-Venezuela

Abstract

Hypericum is one of nine genera forming the family Hypericaceae distributed mainly in temperate regions and tropical mountains. Fresh aerial parts of H. laricifolium Juss. collected by the Pinango road, Merida state, at 3900 m above sea level, yielded 1.2 mL (0.24% w/v) of essential oil by hydrodistn. GC and CG/MS anal. showed the presence of 21 components being α-pinene (20.2%), verticiol (13.4%), 3-methyl-nonane (12.3%), 2-methyl-octane (9.6%) and nonane (7.6%) in major proportions. To the best of our knowledge, this is the first report on the chem. compn. of the Hypericum laricifolium essential oil. [on SciFinder(R)]
