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 hydrodistillation. GC and CG/MS analysis 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 chemical composition of the Hypericum laricifolium essential oil.
Highlights
Hypericum is one of nine genera forming the family Hypericaceae, comprises about 500 species distributed mainly in temperate regions and tropical mountains being most abundant in Europe, Asia, Northern Africa and America [1,2]
Phytochemical studies carried out with different Hypericum species have revealed the presence of bioactive substances like phloroglucinol derivatives, napthodianthrones, flavonoids, phenylpropanes, essential oils, benzophenones and xanthones, showing a wide range of biological properties related to antimicrobial, anticancer, antidepressant, antianxiety, antiviral, cytotoxic and antifungal activities [6,7,8,9]
The chemical composition of Hypericum laricifolium Juss essential oil collected from Mérida-Venezuela has been studied and compared to several Hypericum species reported worldwide
