@@@@This research was to extract and produce xylan from bagasse , which provided a theoretical and methodological instruction for development and utilization of sugarcane by-products. On the basis of single factor test, the response surface method was designed to study the effects of NaOH concentration, liquid material rate and ultrasonic processing time on xylan extraction rate. The results showed that the optimum condition for ultrasonic-assisted extraction of xylan was as follows:NaOH concentration 6%, liquid material rate 38∶1(mL/g), and ultrasonic processing time 28.4 min. Under this condition, the actual average extraction rate of xylan was 28.39%.
