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

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...
