摘　　要：以乌饭树树叶多糖的得率为指标,对水提取-超声波萃取乌饭树树叶多糖的工艺进行考察,并对所得乌饭树树叶多糖进行了卷烟加香试验。以超声温度、料液比、超声时间、超声功率为考察因素,采用单因素和正交试验法同时对乌饭树树叶多糖提取工艺进行优化。确定了水提取-超声波萃取的最佳工艺参数为:超声温度60℃、料液比1∶50(g/mL)、超声时间90 min、超声功率300 W。按此优化条件,乌饭树树叶多糖得率可达到77.10 mg/g。乌饭树树叶多糖卷烟加香应用结果表明,乌饭树树叶多糖能改善烟气质,改善余味。Using yield of Vaccinium bracteatum Thunb. leaves polysaccharides as an index, investigate the technology ofwater-ultrasonic extraction of Vaccinium bracteatum Thunb. leaves polysaccharides. Taking ultrasonic temperature, solid toliquid ratio, ultrasonic time, ultrasonic power as factors, single factor test and orthogonal experimental were used to studythe optimum extraction condition of Vaccinium bracteatum Thunb. leaves polysaccharides. Results showed that the optimumcondition was that ultrasonic temperature of 60 ℃, solid to liquid ratio of 1 - 50 （g/mL）, ultrasonic time of 90 min,ultrasonic power of 300 W, The extraction yield of polysaccharides reached 77.10 mg/g under the optimum condition. Thepractical effects of perfuming indicated that polysaccharides from Vaccinium bracteatum Thunb. leaves could improve andsmooth the flavor quality of cigarette.
