Citrus reticulata Blanco. peel possess various phytochemical compounds which exhibit high-value biological activities. However, the microwave-assisted technique has not been experimentally adopted in essential oil extraction from Citrus reticulate. Therefore, the present study attempted adopt this microwave-assisted hydrodistillation method to extract the essential oil from the mandarin fruit peel and improved extraction method specifications. Fresh ground peels were used as the material and underwent three extraction cycles. Technical conditions for optimal oil yield consisted of raw material/solvent ratio of 1: 3 (g/ml), microwave power of 600W, and time extraction of 55 min. After extraction, essential oil products were analyzed for composition on the GC-MS method. Obtained essential oils featured main ingredients including limonene (97.688%), sabinene (0.12%), β-myrcene (1.394%), (-)-β-pinene (0.273%) and 1R-α- pinene (0.525%). These results suggest the use of Citrus reticulata essential oil in manufacture of antibacterial, antioxidant agents and in cosmetics, food, and pharmaceuticals.
