摘　　要：浸渍提取是制备造纸法烟草薄片的重要环节,浸渍提取液是高质量薄片涂料的主要组分来源.文中结合生产实际,以水作为提取剂,采用正交实验和单因素实验相结合的方法,研究了不同的浸渍温度、浸渍时间和浸渍液比条件下废弃烟梗和烟末中主要化学组分的溶出规律,得到了烟梗和烟末一段浸渍提取的最优条件:烟梗浸渍时间为100min,浸渍温度为60℃,浸渍液比为1∶7,此时水溶性糖和总植物碱的溶出率分别达到50.60%和52.46%;烟末浸渍时间为60min,浸渍温度为70℃,浸渍液比为1∶10,此时水溶性糖和总植物碱的溶出率分别达到73.06%和64.57%.Macerated extraction is an important step of producing reconstituted tobacco sheets by paper-making technology, and the extracting solution is also a major ingredient for making high-quality reconstituted tobacco coa- tings. In this paper, the main chemical components in abandoned tobacco stems and leave powders were extracted by combining an orthogonal test with single-factor experiments, with water as the solvent. Then, the effects of maceration time, maceration temperature and solid/liquid ratio on extraction rate were investigated, and the optimal macerated extraction conditions for abandoned tobacco stems and leave powder were determined. The results show that, under the optimal conditions for abandoned tobacco stems, i. e. , a maceration time of 100 min, a maceration temperature of 60 ℃ and a solid/liquid ratio of 1 ： 7, the dissolution rates of water-soluble sugars and total alkaloid are 50.60% and 52.46% , respectively; and that the dissolution rates respectively reaches 73.06% and 64.57% under the optimal conditions for abandoned tobacco leave powders, that is, a maceration time of 60 min, a macera- tion temperature of 70 ℃ and a solid/liquid ratio of 1 ： 10.
