The essential oil of the fruits of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae) from Lampedusa Island was obtained by hydrodistillation and its composition was analysed. The analyses allowed the identification and quantification of 64 volatile compounds belonging to different classes. The most abundant compounds were nonacosane, heptacosane, hentriacontane and δ-cadinene. Among the volatile compounds identified in the fruits of P. laevigata subsp. angustifolia, 31 are present in other taxa of Apocynaceae, 19 have antimicrobial activity and four are pheromones for the butterfly Danaus chrysippus. The possible ecological role of the volatile compounds found is briefly discussed.
从兰佩杜萨岛采集的杠柳 Periploca laevigata Aiton 亚种 angustifolia(夹竹桃科)的果实精油通过水蒸馏法获得,并对其成分进行了分析。分析鉴定出了 64 种属于不同类别的挥发性化合物。含量最丰富的化合物是非十九烷、十七烷、三十烷和 δ-杜松烯。在杠柳亚种 angustifolia 的果实中鉴定出的挥发性化合物中,有 31 种存在于夹竹桃科的其他分类群中,有 19 种具有抗菌活性,有 4 种是蝴蝶 Danaus chrysippus 的信息素。简要讨论了所发现的挥发性化合物的可能生态作用。
