Pinus cembra L. is a coniferous European mountain range tree rich in oleoresins and essential oils. Twig tips with needles are the most common tree parts used to obtain essential oils. As the whole tree contains volatiles, the essential oil composition from different parts was studied, including twig tips with needles from the bottom, the top and the cone bearing branches, cones, twigs without needles from the lower and upper part of the crown as well as wood and bark from the trunk. The variability in essential oil composition between these plant parts and between individual trees has been studied using multivariate statistical analyses. α-Pinene was present in all samples, being highest in cones (49.3%) and lowest in sapwood (0.7%). Twig tips with needles from different parts of the crown had similar essential oil composition with α-pinene (43.9–48.3%), β-phellandrene (13.1–17.2%), β-pinene (6.6–9.3%), germacrene D (5.1–6.8%) and limonene (4.1–6.1%) as main compounds. Twig essential oils had usually more β-phellandrene (23.9–29.8%) than α-pinene (23.3–24.3%) and also appreciable amounts of β-pinene (13.5–15.1%) and limonene (11.9–17.9%). Cone essential oils contained mainly α-pinene, β-pinene (20.1%) and limonene (13.9%). The essential oils from wood and bark were rich in diterpenes as cembratrienol (4.9–21.4%), cembrene (4.8–14.3%) and methyl daniellate (2.7–6.8%). Sapwood distillates contained also notable amounts of alkane derivatives. Finally, the solvent free SPME technique has been employed to analyse the volatiles in the plant parts. For needles and cones the observed patterns were in good accordance with the compositions of the respective essential oils.

通过精油和SPME分析评估的奥地利萨尔茨堡阿尔卑斯山林中树木之间以及树木之间的松树皮挥发物的变异性

松树L.是一种富含油树脂和精油的欧洲针叶树。细枝针尖是用于获取香精油的最常见的树木部位。由于整棵树中都含有挥发物,因此研究了不同部位的精油成分,包括从底部,顶部和带有圆锥形支路的树枝,树枝,顶部和下部不带针的树枝的针尖。如树干上的木头和树皮。这些植物部分之间以及每棵树木之间的精油成分变异性已使用多元统计分析进行了研究。所有样品中均存在α-samples烯,锥状细胞最高(49.3%),边材最低(0.7%)。树枝冠上不同部位的细枝针尖的精油成分与α-pine烯相似(43.9–48.3%),主要成分为β-水芹烯(13.1–17.2%),β-pine烯(6.6–9.3%),germ三丁烯D(5.1–6.8%)和li烯(4.1–6.1%)。嫩枝精油中的β-pine烯(23.9–29.8%)通常比α-pine烯(23.3–24.3%)多,β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)的含量也可观。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的成分非常吻合。主要成分为β-pine烯(6.6–9.3%),germ啶D(5.1–6.8%)和li烯(4.1–6.1%)。嫩枝精油中的β-pine烯(23.9–29.8%)通常比α-pine烯(23.3–24.3%)多,β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)的含量也可观。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。主要成分为β-pine烯(6.6–9.3%),germ啶D(5.1–6.8%)和li烯(4.1–6.1%)。嫩枝精油中的β-pine烯(23.9–29.8%)通常比α-pine烯(23.3–24.3%)多,β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)的含量也可观。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。1%)作为主要化合物。嫩枝精油中的β-pine烯(23.9–29.8%)通常比α-pine烯(23.3–24.3%)多,β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)的含量也可观。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。1%)作为主要化合物。嫩枝精油中的β-ph烯(23.9–29.8%)通常比α-pine烯(23.3–24.3%)多,β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)也可观。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。3%),还有相当数量的β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。3%),还有相当数量的β-pine烯(13.5–15.1%)和li烯(11.9–17.9%)。锥形精油主要包含α-pine烯,β-pine烯(20.1%)和li烯(13.9%)。木材和树皮中的精油中富含二萜类化合物,如西柏三烯酚(4.9–21.4%),西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。西柏烯(4.8–14.3%)和丹尼尔酸甲酯(2.7–6.8%)。边材馏出物还包含显着量的烷烃衍生物。最后,采用无溶剂的SPME技术分析植物部位中的挥发物。对于针和锥,观察到的图案与相应的精油的组成非常一致。
