Liquid chromatography fingerprint analysis and antioxidant activity of selected lavender species with chemometric calculations.

ABSTRACT: The extracts of seven Lavandulae species (Lavandula stoechas, Lavandula lanata, Lavandula viridis, Lavandula angustifolia "Rosea", Lavandula angustifolia "Afropurpurea", Lavandula angustifolia and one unknown) were analyzed using the reversed-phase-high performance liquid chromatography-diode array detection (RP-HPLC-DAD) with gradient elution technique to obtain the chromatographic fingerprint profiles. The HPLC analysis was performed using the Kinetex RP18 chromatographic column and eluent consisting of methanol-water-0.1% formic acid (5-100% (v/v)) at 30 °C with the run time of 60 min. and the detection wavelength 280 nm. The chromatograms were preliminary processed with the smoothing, noise reduction, background subtraction and alignment using the SpecAlign program (version 2.4.1). The
