Molecules, Vol. 29, Pages 1740: Phytochemical Composition and Antimicrobial Properties of New Lavandula angustifolia Ecotypes Molecules doi: 10.3390/molecules29081740 Authors: Izabela Betlej Bogusław Andres Tomasz Cebulak Ireneusz Kapusta Maciej Balawejder Natalia Żurek Sławomir Jaworski Agata Lange Marta Kutwin Elżbieta Pisulewska Agnieszka Kidacka Barbara Krochmal-Marczak Piotr Boruszewski Piotr Borysiuk The purpose of this study was to characterize ethanol extracts from leaves and flowers of two ecotypes (PL—intended for industrial plantations and KC—intended for cut flowers) of Lavandula angustifolia Mill. The plant was cultivated in 2019 in southern Poland as part of a long-term research plan to develop new varieties resistant to difficult environmental conditions. The collected leaves and flowers were used to prepare ethanol extracts, which were then analyzed in terms of phytochemical composition and antioxidant, bactericidal, and fungicidal properties. Using UPLC techniques, 22 compounds belonging to phenolic acids and flavonoids were identified. UPLC test results indicated that ethanol extracts from leaves and flowers differ in phytochemical composition. Lower amounts of phenolic acids and flavonoids were identified in leaf extracts than in flower extracts. The predominant substances in the flower extracts were rosmarinic acid (829.68–1229.33 µg/g), ferulic acid glucoside III...
