Abstract
Rosemary (Rosmarinus officinalis L.) has been a significant herb with recognized antiseptic, astringent, antifungal, antibacterial, and antioxidant properties. This study aimed to optimize the microwave-assisted distillation process for extracting rosemary essential oil by investigating the effects of feed-solvent ratio, distillation power, feed leaf size, and distillation time on the yield. Optimal extraction conditions were determined as a feed-solvent ratio of 1:1, distillation power of 380W, distillation time of 25 minutes, and feed leaf size of 0.8-1 cm, resulting in a maximum yield of 2.7%. The study provided a comparative analysis of essential oil quality and quantity and proposed a mechanism for microwave-assisted extraction of rosemary essential oils.
