Characterization and enantiomeric distribution of some terpenes in the essential oil of a Uruguayan biotype of Salvia sclarea L.

Abstract

A biotype of clary sage (Salvia sclarea L.) growing in Uruguay was evaluated for its suitability to be cultivated in Uruguay. Essential oils from the inflorescences and leaves of plant harvested at full flowering and early seed ripeness stages were obtained by steam distillation and characterized by GC and GC-MS (quadrupole). Twenty-seven components (91-98% of the total composition) were identified. The oil was characterized by a high content of linalool (8-22%), linalyl acetate (39-48%) and sesquiterpenes, with germacrene D (8-20%) and (E)-β β β β β-caryophyllene (3-5%) as the main components. The enantiomeric distribution of α α α α α-pinene, sabinene, β β β β β-pinene, limonene, linalool, linalyl acetate and germacrene D was studied by multidimensional HRGC-HRGC. The development stage did not influence the oil composition or the enantiomeric distribution of the studied components of the clary sage biotype over the period of evaluation. It is concluded that clary sage can be grown as an economically viable crop in the south of Uruguay.

GC Analyses of Salvia Seeds as Valuable Essential Oil Source

“…Similar to the studied S. sclarea essential oil, the sesquiterpenes were mainly composed of germacrene-D, -copaene, and bicyclogermacrene in plant inflorescence according to Carrubba et al [11] and Lorenzo et al [33]. In our sample, the essential oil of S. sclarea flowering shoots raised in experimental plots in India was characterised by linalool (36.6-41.9%) and linalyl acetate (13.2-19.2%) as main compounds [23].…”

Antimicrobial Activity of Some Salvia Species Essential Oils from Iran

“…In the oil of S. multicaulis, camphor (11.0%), 1,8-cineole (10.7%), borneol (8.9%) and α-pinene (7.5%) have been characterized as main compounds from fifty identified components (Morteza-Semnani et al, 2005). The chemical composition of the essential oils of S. sclarea from different countries has already been published and linalool, linalyl acetate, terpineol, geraniol, geranyl acetate, germacrene D, -caryophyllene and sclareol were identified (Souleles and Argyriadou, 1997; Moretti et al, 1997;Peana et al, 1999;Pitarokili et al, 2002;Lorenzo et al, 2004).…”

Sicilian lemon oil: Composition of volatile and oxygen heterocyclic fractions and enantiomeric distribution of volatile components

“…Enantiomeric distribution was the object of five articles 30, 34–37; four of them 30, 34–36 dealt with the analysis of laboratory extracted oils, whereas the other one reported results relative to laboratory and commercial oils.…”
