Essential oil composition of the fruits of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae – Periplocoideae)
2011
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 i…
Essential oils composition of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae – Periplocoideae)
2012
The essential oil of roots, branches, leaves, flowers and fruits of Periploca laevigata Aiton subsp. angustifolia (Apocynaceae) from Lampedusa Island has been obtained by hydrodistillation and its composition analysed. The analyses allowed the identification and quantification of 86 volatile compounds. Branches showed the higher diversity with 57 compounds followed by fruits with 33, roots with 23, flowers with 16 and leaves with six compounds, respectively. In the matrices examined three constituents, heneicosane, docosane and tricosane are in common, although with different percentages. At least the most abundant compounds found in the matrices have been reported to have several biologica…
First records of pollinators of two co-occurring Mediterranean Apocynaceae
2011
This article presents results of a field survey of pollinators of two Apocynaceae, Periploca laevigata subsp. angustifolia (Labill.)Markgraf (Periplocoideae) and Caralluma europaea (Guss.) N.E.Br. Asclepiadoideae) co-occurring on Lampedusa Island, Mediterranean sea. Fifteen species within nine families of Diptera have been identified as pollinators of the two plants. The families involved are Tephritidae, Milichiidae, Trixoscelididae, cathophagidae, Anthomyiidae, Muscidae, Calliphoridae, Sarcophagidae, Rhinophoridae. Families of Muscidae and Sarcophagidae are the more represented, respectively with four and three species. P. laevigata subsp. angustifolia seems to have a broader spectrum of …
