Salvia sclarea L. or clary sage is cultivated worldwide in temperate and sub-tropical climates, as an ornamental and essential oil (EO) bearing plant. EO is obtained from fresh spikes in full flowering stage and is recognized as an important com. product for food, beverage and cosmetic industries. This study investigated the EO composition of S. sclarea grown in Serbia (Southeast Europe) obtained by two different methods, steam (SD) and hydrodistillation (HD). GC-MS anal. identified oxygenated monoterpenes as the main class of compounds for all EOs (between 81.8% and 88.2% depending on the distillation process). The most abundant oxygenated monoterpenes were linalyl acetate and linalool. In addition, in vitro antimicrobial (modified resazurin microtitre-plate assay) and antioxidant activities (DPPH· assay) and total polyphenol content of obtained EOs were also evaluated. According to the assay used for the evaluation of the antibacterial activity, Gram-neg. bacteria were more sensitive to S. sclarea EO in comparison to Gram-pos. bacteria. EOs exhibited low antioxidant capacity, below 3% neutralized DPPH· radicals, reaching up to approx. 400 μg AAE mL-1. This study also investigated a possibility for predicting retention indexes (RIs) of compounds isolated from EOs. In total, 78 exptl. obtained RIs were applied to construct the prediction model. The quant. structure-chromatog. retention relationship (QSRR) model was used to anticipate the exptl. obtained RIs. Five mol. descriptors were selected by factor anal. and genetic algorithm to predict RIs. The obtained accuracy of the QSRR model reached r2 = .912, which showed that these models might be applied for predicting retention indexes. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3SDS of cas: 105-87-3).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.SDS of cas: 105-87-3
