Composition and antimicrobial activity of the essential oil of Hypericum rumeliacum subsp. apollinis (Boiss. & Heldr.)

Phytother Res. 2003 Feb;17(2):152-4. doi: 10.1002/ptr.1093.

Abstract

The composition and the antimicrobial activity of the aerial parts of Hypericum rumeliacum are reported. Analysis was carried out by GC/MS. The major constituents were alpha-pinene (43.80%), beta-pinene (9.82%), dehydro-aromadendrene (6.81%) and alpha-copaene (5.41%). The essential oil showed a moderate in vitro activity against the six Gram negative and positive bacteria and a stronger one against the three-tested pathogenic activity.
