الملخص

Recently, the industry of Natural Bioactive Compounds (NBAC) is expanding dramatically due to its high medical potentials. High bioactivity of natural extracts from a wide range of plants is evident from the reported literature. For instance, NBACs show antibacterial, antifungal, antimicrobial, anti-inflammatory, anticancer and antioxidant activities. Teucrium stocksianum Boiss. from the Lamiaceae family is a known herb in the traditional medicine in United Arab Emirates. Multiple bioactivities of T. stocksianum were recorded such as anti-inflammation, analgesia, antioxidation, anticancer, antinociception and antimicrobial bioactivity. In this thesis, the extraction of NBACs from T. stocksianum was studied with Microwave-assisted extraction using Deep eutectic solvent (MAE-DES). The resultant yield of extraction and antioxidant capacity were compared with the results of Ultrasound-assisted extraction with water, Hydrodistillation and Soxhlet with four different solvents (methanol, ethanol, Diethyl ether and n-hexane). MAE-DES showed higher results in term of yield (54.18%) and antioxidant bioactivity (21.67 mg Trolox equivalent/g dry weight). The effects of operating parameters for MAE-DES method on the total antioxidant capacity of extracts and the yield of extraction were investigated. Four independent variables, solid–liquid ratio (1:10, 1:30, and 1:50 ratio of raw material to DES, w/v), microwave power (220, 400, and 800 W), microwave time (60, 120, and 180 s), and DES concentration (30%, 50%, and 70%)—were used, and the optimized conditions were found to be 1:50, 400 W, 180 s and 30%.
