Abstract: Microwave-assisted extraction (MAE) of cherry-kernel oil was studied with single-factor method and orthogonal method. The affecting factors, such as extraction time, temperature and ratio of material to solvent were researched emphatically in the experiment. The optimal conditions were obtained as follows : extraction time 15 min, extraction temperature 50 ℃ and ratio of material to solvent 1:6(W/V). Compared with the other extraction methods, the results showed that time is shortened obviously, 1/12 of the time of solvent extraction method and 1/16 of the time of Soxhlet method. The consumption of solvent is less than solvent extraction method.

Key words: microwave extraction, cherry-kernel oil, extraction technology
