| 摘 要： | 本文采用超声提取法，从菜籽饼粕中提取多糖，用苯酚-硫酸比色法测定菜籽多糖含量。探讨了影响多糖提取率的主要因素（提取时间、料液比、次数），并用正交设计实验确定最佳提取工艺。结果表明：超声提取饼粕中多糖的最佳工艺为时间75min，料液比为1：40，次数为2，多糖产率为1、99％；超声法具有提取时间短、节省溶剂、提取率高的特点。

| Abstract: | Using ultrasonic extraction methods, RP was extracted from rapeseed-meal, and the content was determined by phenol-vitriol colorimetry. The main factors (extracted time, solid liquid ratio, times) were investigated, and finally the optimal extracting conditions were assured by orthogon:d experiments, while the content of RP was calculated. The results showed that: the optimal ultrasonic extracting conditions: 75min, 1:40,2 times and the content was 1.99%; Ultrasonic extraction was a better method for RP extraction with less time and solution, higher extraction rate. |
