THE CHEMICAL CONSTITUENTS OF THE ESSENTIAL OILS FROM THE LEAVES OF CINNAMOMUM APPELIANUM AND CINNAMOMUM PAUCIFLORUM

Cinnamomum appelianum Sehewe and C. pauciflorum Nees were collected from West Huhei in 1983 and analysed by GC/MS/DS on the Finnigan 4510 instrument. The essential oils were prepared from fresh leaves by steam distillation. The properties of the essential oil of C. appelianum were determined as follows: the yield of oil 1.05%, d₂₀²⁰ 0.9547, n_D²⁴ 1.4804, α_D²¹ -2.26; 21 compounds were identified with the major components 1,8eineole (37.02%)and bornyl acetate(16.24%). The properties of the essential oi lof C. pauciflorum were determined as followst: he yield of oil 0.19%, D₂₀²⁰0.9414, n_D²⁴ 1.4944, α_D²¹-13.04; 33 compounds were identified with major components α-pinene(9.09%), 1,8-cineole(8.27%), geraniol(6.03%), geranial(5.90%), geranyl acetate (4.94%) and safrole (4.43%).
