Lavender essential oil was well known for its pleasant scent and wide range of uses in the fragrance business. This study contrasted traditional steam distillation with ultrasound-assisted extraction (UAE), an alternate method for extracting lavender essential oil. The extracted oil's chemical makeup, antioxidant activity, antibacterial qualities, extraction yield, and potential for perfume formulation were all examined. UAE outperformed steam distillation in terms of extraction yield at the experimental conditions used. According to GC-MS analysis, the most common volatile chemicals found in the extracted oil were camphor (21.18%), α-thujene (16.27%), and endo-borneol (14.05%). When tested against the bacteria, the lavender essential oil shown significant antimicrobial and antioxidant action. During hedonic evaluation, perfume compositions made with the extracted oil showed acceptable sensory qualities. Under the conditions examined, UAE needed less time for extraction and less solvent than steam distillation. According to the results, ultrasound-assisted extraction may be a viable substitute method for extracting lavender essential oil and using it in perfumery. It was suggested that more research be done to assess its environmental performance and large-scale usability.
