摘　　要：通过对茶叶中咖啡因提取方法的改进研究,实验结果更明显,更有利于实验教学。提取方法:回流提取加振摇技术,蒸馏浓缩加振摇技术,浓缩粉末后,粉末脱离蒸发皿的使用,升华时,滤纸与粉末高度的定量控制,加热时,受热均匀地控制。It will obtain more obvious result and more favorable to experiment teaching to improve the study on extracting caffeine from tea. The extracting method is that; reflux extracting followed by vibrating shaking technology; distilling and concentrating followed by vibrating shaking technology; concentrated powder breaking away from evaporating dish; quantitative controlling the filter paper and powder height when sublimating controlling heated evenly as heating.
