Abstract:
Objective: An ultrasonic method for the extraction of polysaccharides from Ligustrum vicaryi was investigated and optimized. Method: Using single factor and L9 ( 34 ) orthogonal design, the effects of ultrasonic time,ultrasonic frequency, extraction temperature and the ratio of solid to liquid were considered, the comprehensive evaluation was guided by the content of polysaccharides determined by phenol-sulfuric acid method. Result: The effects of 4 factors on extracting polysaccharides component in order were extraction time,ultrasonic frequency, extraction temperature, solid-liquid ratio. The optimum extracting conditions were: the ratio of solid to liquid was 1∶ 30( m/V) ; extraction time was 80 min; extraction temperature was 100℃,ultrasonic frequency was 300 W.
