废弃烟叶的综合利用现状

在废弃烟叶的综合利用中可得到烟碱、茄尼醇、氨基酸、有机酸、有机复混肥及活性碳等烟草产品.通过对烟叶中各种有用成分的提取、纯化和测量,对它们的性质有了进一步的了解,特别是对茄尼醇在光照下以及在不同溶剂中的稳定性有更进一步的认识.结合国内外废次烟叶综合利用情况,归纳和比较了烟碱、茄尼醇的主要提取和测量方法,总结了各种烟草提取物的性质及应用,以便更好地利用废次烟叶,得到更多有价值的烟草产品.

A Aummary of the Comprehensive Utilizations of Discarded Tobacco Ieaves

The comprehensive utilizations of discarded tobacco leaves are discussed, from which different products such as nicotine,solanesol,amino acid,organic acids,organic fertilizer and activated carbon can be gotten. In extracting,purifi-cating and measuring useful composition of different kinds from tobacco leaves, their properties, especially the stability of solanesol in the sunlight and different solvents have been further research. Comparing and summing up the methods of nicotine, solanesol and their properties and utilizations, as well as the comprehensive utilizations at home and abroad, it helps to make good use of tobacco waste and obtain more tobacco leaves products of high value.
