Essential oils composition of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae - Periplocoideae).
Summary of "Essential oils composition of Periploca laevigata Aiton subsp. angustifolia (Labill.) Markgraf (Apocynaceae - Periplocoideae)."
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 biological activities. 2-Hydroxy-4-methoxybenzaldehyde identified in the roots as the most abundant component (70.7%) and present with 8.3% in the branches is a potent tyrosinase inhibitor present in several African medicinal plants, and thus being used as an ingredient in cosmetic and other medicinal products, primarily in relation to hyperpigmentation. Among the compounds identified, several play a role as semiochemicals for many animals, and 28 allomones, 43 pheromones, 21 kairomones have been identified. P. laevigata subsp. angustifolia in Lampedusa Island is host to a community of visitors, and the possible ecological role of the volatiles found is briefly discussed.

Medical and Biotech [MESH] Definitions
Oils, Volatile
Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.
Tanacetum Parthenium
An aromatic perennial plant species that has been used to treat migraines, arthritis, and as a febrifuge. It contains TANNINS, volatile oils (OILS, ESSENTIAL), and sesquiterpene lactones, especially parthenolide.
Calendula
A plant genus of the family ASTERACEAE. Members contain CAROTENOIDS, essential oils (OILS, VOLATILE), flavonoids, mucilage, SAPONINS, and STEROLS. The plants are used both topically and internally. The common name of Marigold is also used for TAGETES.
Monoterpenes
Compounds with a core of 10 carbons generally formed via the mevalonate pathway from the combination of 3,3-dimethylallyl pyrophosphate and isopentenyl pyrophosphate. They are cyclized and oxidized in a variety of ways. Due to the low molecular weight many of them exist in the form of essential oils (OILS, VOLATILE).
Hypericum
Genus of perennial plants in the family CLUSIACEAE (sometimes classified as Hypericaceae). Herbal and homeopathic preparations are used for depression, neuralgias, and a variety of other conditions. Hypericum contains flavonoids; GLYCOSIDES; mucilage, TANNINS; volatile oils (OILS, ESSENTIAL), hypericin and hyperforin.
