STUDY ON EXTRACTION OIL OF THE SEABUCKTHORN SEEDS WITH MICROWAVE-ASSISTED METHOD

Effects of different factors, such as extraction solvent, time, temperature, the ratio of liquid to solid and the microwave power etc on the seabuckthorn oil yield were explored with oil yield as a value standard. The optimal technology was based on orthogonal array design experiment were obtained, i.e., ethyl acetate as extraction solvent, extraction time of 150 s, 55 ℃ of extraction temperature, 500 W of microwave power. Finally, a comparative analysis with Soxhlet, microwave-assisted extraction was finished. The experimental results demonstrated that the microwave -assisted method was low energy consumption, saving solvent and high yield of oil.
