Abstract
This research is a comprehensive study of the chemical composition, antimicrobial, and antioxidant properties of the essential oil derived from Lavandula angustifolia, commonly known as lavender, sourced from the Hamadan province in Iran. The study utilized Gas Chromatography (GC) analysis to scrutinize the chemical composition of the extracted essential oil. Antimicrobial activity was evaluated by determining the minimum inhibitory concentration (MIC) through a series of micro dilutions, while the antioxidant activity was estimated using the DPPH assay. Variations in the chemical composition of the essential oils from the plant’s flowers and leaves were observed, with linalool, linalyl acetate, camphor, and borneol identified as the predominant components in all essential oils. The study revealed significant antimicrobial and antioxidant activities in the essential oil from L. angustifolia. Furthermore, the study further investigated the variations in these properties based on the part of the plant used (leaves or flowers) and the plant’s conditions (purchased or cultivated). The findings indicate that L. angustifolia essential oil holds potential for therapeutic and natural medicine applications.
