Chemotaxonomic Evaluation by Volatolomics Analysis of Fifty-Two Genotypes of Myrtus communis L.

Abstract

A population of 52 genotypes of Myrtle (Myrtus communis L.), selected in the framework of a domestication program and growing in the same collection field at Oristano (Central Western Sardinia, 39°54′ N 8°35′ E), was analyzed by GC/MS for leaf essential oil composition. The chemical composition of essential oils was quite variable with a number of compounds ranging from 31 to 78 depending on cultivar. One hundred and eighteen compounds were globally identified in the various genotypes. However, α-pinene, limonene, 1,8-cineole, α-terpineol, and linalool always resulted as main components with few differences among samples. Minor compounds have been the determining factors in differentiating or associating genotypes in the outputs of a principal component analysis (PCA), where the results of another analysis of fruit essential oils of the same genotypes were also jointly used. Genotypes were discriminated according to mother plant characterization or ecological variables, such as site altitude, soil nature, and presence or absence of calcareous soils in the substrate of the localities of origin.

Liposomal Formulations to Improve Antioxidant Power of Myrtle Berry Extract for Potential Skin Application

“…Myrtle is widely distributed in the Mediterranean area, and different parts of the plant are traditionally used for many purposes. The berries and leaves are used as flavoring agents and in the production of a liqueur typical to Sardinia (Italy) [ 1 , 2 , 3 , 4 ]. Other uses for myrtle include animal feed and cosmetic and pharmaceutical applications.…”

“…Interestingly, myrtle essential oils from two locations of Liguria, Italy were rich in α-pinene (41.6% and 28.9%, respectively), while lacking myrtenyl-acetate and myrtenol (26). Moreover, the EOs obtained from 52 genotypes of M. communis growing in the same field at Oristano (Sardinia, Italy) contained limonene, 1,8-cineole, α-pinene, linalool, and α-terpineol as principle components with few differences among the samples (27,28). The essential oil of M.…”

The essential oil of M. comminis from Iran origin is rich in α-pinene (27.87%), 1,8-cineole (20.15%) and linalool (10.26%) (29).…”
