The essential oils of some rosemary cultivars

摘要: Twenty-three named cultivars of Rosmarinus officinalis L. were examined. These cultivars, derived from five botanical varieties, show wide ranges in the leading components: 0.06–57.45% α-pinene, 3.55–42.69% 1,8-cineole, 0.20–56.45% camphor, 0.66–21.03% bornyl acetate, and 0.40–14.69% borneol. They may be grouped into six chemical groups: (1) α-pinene > (2) 1,8-cineole (3) camphor + camphene (4) (5) (6) borneol acetate camphor.
