Lavandula angustifolia L. is a perennial plant with multiple uses in the cosmetic, pharmaceutical, food, aromatherapy industry and for ornamental purposes. Six lavender cultivars were used for measurements, laboratory analyses and decorations: L. angustifolia 'Hidcote', L. angustifolia 'Sevstopolis', L. angustifolia 'Nana Alba', L. angustifolia 'Dwarf Blue', L. angustifolia 'Blue Scent', Lavandula x intermedia 'Grosso', grown under field conditions. The ATR-FTIR spectra of various tissues of lavenders used in this experiment have revealed presence of a wide range of biochemical compounds with pharmaceutical importance. The content of lycopene, β-carotene, flavonoids, tannins and the antioxidant activity of each cultivar were determined, using UV-Vis spectroscopy. The best antioxidant activity has been noted in the 'Sevtopolis' cultivar, the 'Blue Scent' has the highest percentage of lycopene (3.47 mg/100 g) and the 'Dwarf White' cultivar the large amount of β-carotene (3.25 mg/100 g). The ornamental qualities have been highlighted by making decorations to create a relaxing space. The data obtained will help to identify the cultivars with the most biologically active principles as well as those with special decorative qualities.
