Microwave assisted extraction is an advanced technique of extraction process. This technique developed for the extraction of oil from natural plants using the microwave energy at atmospheric pressure. Microwave assisted extraction process used for the extraction of eucalyptus oil from Eucalyptus umbellata leaves, which was optimize with using full factorial design to find out the optimum conditions. Three parameters are involved in MAE, like extraction time, microwave power and drying period for optimization. For experimental procedure, four microwave powers such as 250W, 500W, 750W, and 1000W required with extraction time at higher level for 150 min. The result of this study is that the higher percentage of the yield is 0.49% (w/w) delivered at the 1000W with optimum 130 min. And also observed that the yield% directly proportional to the microwave power and dryness of leaves. This study concluded that the microwave assisted extraction gives the higher eucalyptus essential oil with shorter extraction time.
