The composition of the volatile compounds isolated by simultaneous distillation-extraction (SDE) and headspace-solid phase microextraction (SPME) from flowers of Magnolia grandiflora growing in Cuba was investigated by GC/FID and GC/MS. Sixty-seven and thirty-four components were obtained by SDE and SPME, respectively. beta-Pinene (10.5%), geraniol (7.4%) and germacrene D (6.2%) were the main constituents of the volatile oil isolated by SDE, while (E)-beta-ocimene (24.6%), geraniol (18.9%), beta-elemene (11.2%) and germacrene D (9.9%) were the most abundant in the headspace of the flowers, respectively.
采用气相色谱/氢火焰离子化检测器（GC/FID）和气相色谱/质谱联用仪（GC/MS），对古巴种植的广玉兰花通过同时蒸馏萃取（SDE）和顶空固相微萃取（SPME）分离得到的挥发性化合物组成进行了研究。通过SDE和SPME分别获得了67种和34种成分。β-蒎烯（10.5%）、香叶醇（7.4%）和杜松烯D（6.2%）是通过SDE分离得到的挥发油的主要成分，而（E）-β-罗勒烯（24.6%）、香叶醇（18.9%）、β-榄香烯（11.2%）和杜松烯D（9.9%）分别是花朵顶空中含量最高的成分。
