Abstract：In order to investigate the process of ultrasonic-semi-mimetic extraction of polysaccharides from Sanghuangpo-rus vaninii,a multifaceted investigative approach was employed,encompassing a single-factor test and a Box-Behnken response surface design,to thoroughly examine the impact of six key factors on the extraction of polysaccharides from the fruiting bodies of Sanghuangporus vaninii.These factors include pH,material-liquid ratio,extraction time,and extraction temperature.The results demonstrated that the optimal extraction process conditions were pH of the first extraction solu-tion=3,pH of the second extraction solution=10,pH of the third extraction solution=9,a material-liquid ratio of 1∶46 g·mL-1,and an extraction time of 30 min.These conditions yielded an extracted amount of polysaccharide from Sanghuangporus vaninii fruit body of 12.69 mg·g-1,which was in close agreement with the predicted value of 12.90 mg·g-1,with a relative error of 1.63％.The extraction process examined in this study is highly efficient and energy-saving,making it a viable method for the efficient extraction of Sanghuangporus vaninii polysaccharides.The research results provide a reference basis for the efficient extraction of polysacchride.
