摘　　要：针对传统索氏抽提法实验中抽提筒的不足进行改进。在抽提筒下端虹吸口处垫上约1 cm高度的脱脂棉,或在抽提筒距离底部约0.5 cm处固定孔径为20～30μm的砂芯板。选用花生、猪肥膘为原材料,进行对比实验,在实验过程中可以看出改进后的装置每次的虹吸彻底、效果明显,从实验数据中看出改进后的装置提取效率更高,可减少实验时间。Improvement has been made compared with the traditional extraction with tube of Soxhlet extractor in this study.Definitely,an absorbent cotton pad about 1cm high was put to cover the mouth of siphon arm,or a aperture in diameter of about 20～30μm was fixed 0.5cm below the core plate.Using peanuts,pig fat as raw materials to detect the improved Soxhlet extractor.The experimental results showed that the siphon was completely higher extraction efficiency and extraction time could be reduced.
