摘要： This study was conducted to evaluate the influence of combined high-intensity ultrasonic power/hot air drying on quantity and chemical constituents of essential oil of peppermint leaves. According to the experimental findings, in comparison with the fresh leaves, both increment and decrement were observed in yielded essential oil from the dried samples. Increasing drying temperature in the practiced range reduced the oil yield. The maximum oil yield (26.42 g/kg dry matter) belonged to the samples dried at 40 degrees C and 360 W while the minimum value (9.93 g/kg dry matter) was obtained at air temperature of 70 degrees C with no ultrasonic power. Both the air temperature and ultrasonic power showed no definite influence on main chemical groups of the oil. In point of quality view, drying treatment of 70 degrees C and ultrasonic power of 270 W produced the highest quality essential oil.
