摘要: Hydro-distilled essential oil of the aerial parts Hypericum japonicum Thunb. ex Murray (Hypericaceae), grown in northern India was analyzed by gas chromatography (GC) and chromatography–mass spectrometry (GC–MS). A total seventy constituents representing 93.6% composition have been identified. Major were 2-methyl octane (24.9%), n-nonane (21.4%), (2Z)-nonenol (16.5%), n-decanal (8.2%) allo-aromadendrene epoxide (3.3%). The characteristic H. japonicum presence higher amount aliphatic compounds (82.5%) compared with terpenoids.
