毛桂和少花桂叶精油的化学成分

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

摘要: 湖北省鄂西自治州产毛桂和少花桂叶精油,分别使用Finnigan-4510型毛细管气相色谱/质谱/电子计算机联用(GC/MS/DS)方法进行了化学成分分析。从毛桂叶精油中共检出61个成分,鉴定了其中21个化合物,占精油总量的76.39%,主要成分为1,8-桉叶油素(37.02%)和乙酸龙脑酯(16.24%)。从少花桂叶精油中共检出60余个成分,鉴定了其中33个成分,占全精油的77.85%,含量较高的有α-蒎烯(9.09%)、1,8-桉叶油素(8.27%)、香叶醇(6.03%),香叶醛(5.90%),乙酸香叶酯(4.94%)和黄樟油素(4.43%)等。

Abstract: 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%).
