Abstract
The polysaccharides were extracted from lyceum barbarum by ultrasonic-microwave assisted extraction,and the influences of the solid-to- liquid ratio,extraction temperature,microwave power,ultrasonic power,extraction time,ultrasonic extraction time on extracting rate of polysaccharides from lyceum barbarum were studied by orthogonal tests.The optimal extraction technology was as follows;solid-to-liquid ratio of 1:10(g/mL).microwave time of 6min,microwave temperature of 100℃,microwave power of 300W,ultrasonic power of 80W,ultrasonic temperature of 70℃and ultrasonic time of 20min.
