They are 1,1-diethoxyethane, α-thujene, α-pinene, camphene, sabinene, β-pinene, myrcene, α- phellandrene, p-cymene, limonene, cineole, γ-terpinene, fenchone, camphor, terpinen-4-ol, α-terpineol, estragole, verbenone, fenchol acetate, carveol, trans-fenchol acetate, carvone, anethole, anisaldehyde, trans-anethole, methoxyphenyl acetone and benzoic acid, 4-methoxy-, othylester. The limonene is 57.8% in the essential oil from leaves, 34.2% from flowers, 13.1% from fruits, The trans-anethole is 21.8% in the essential oil from leaves, 41.2% from flowers, 63.4% from fruits. |
