| Abstract:
The genus Salvia L. (Laminaceae) has about 900 recognized species, being distributed almost all over the world. Salvia lavandulifolia Vahl can be found in the calcareous mountains from the western Mediterranean area (France, Spain, Algeria and Morocco). The subspecies vellerea - the target of this study- is a spontaneous shrub endemic to the South and East of Spain. Commercially this species is used by the pharmaceutical, cosmetic, and food industries as an important source of essential oil and its leaves are an ingredient of infusions and condiments due to the health-promoting properties possessed by these shrubs. For the present work a survey in the areas of Murcia and Albacete (Southeastern Spain) has been made in order to define the essential oil yield (EO%), volatile profile (GC-MS), and antiradical scavenging activity (AA%) exhibited by the distillate from these plants against the radical DPPH•. A total of 50 plants belonging to five wild populations have been prospected and the analytical results have allowed for the identification of the most common chemotypes (Gas chromatography-Mass spectrometry), their essential oil yield (%EO weight/volume), and their antiradical scavenging activity (AA%) against the radical DPPH•. Chemotypes found correspond to 1,8-cineol-camphor (40.7-23.9%) with 5.8% EO yield and 45.1% (AA); 1,8-cineol-camphor (36.9-31%), 4.7% EO, 40.1% (AA); camphor-1,8-cineol-camphene (28-26-8%), 1.7% EO, 41.9% (AA); camphor-1,8-cineol-linallyl acetate-linalool (23.6-19.7-15.3-7.5%), 3.2% EO, 39% (AA); camphor-1,8-cineol-camphene-borneol (32.8-18.7-6.5-3.4%), 2.0% EO, 42.1% (AA). These results show the great intraspecific variability exhibited by these shrubs regarding the essential oil yield and composition, whereas for AA no important differences were seen among the populations analyzed. | |
