Essential oil components were extracted from Lavandula angustifolia (Lavender) flowers using pressurized fluid extraction (PFE). A Box-Behnken design was used to optimize the effective extraction variables. The chemical composition of extracted samples was analyzed by gas chromatograph-flame ionization detector column. For achieving maximum % extraction yield the temperature, pressure, and dyna...

The current study describes the composition of Salvia lavandulifolia (Vahl) essential oils (SlEOs) obtained from plants cultivated in Murcia (Spain), as determined by gas chromatography. Relative and absolute concentrations, the enantiomeric ratios of chiral compounds and the in vitro antioxidant, antienzymatic and antimicrobial activities are described. The main components of the SlEOs were ca...
