A method of reducing the amount of matrix-bound NNK in cured tobacco plant material is provided comprising reducing the amount of lignin in the cured tobacco plant material. A further method of reducing the formation of matrix-bound NNK during the curing of tobacco plant material is described comprising reducing the amount of lignin therein prior to curing.

A method for preparing a tar extract from a discarded cigarette butt and use of the tar extract in a cigarette includes the following steps: (1) adding the discarded cigarette butt to an extraction solvent, and carrying out microwave-assisted extraction to obtain an extraction solution; and (2) centrifuging the extraction solution, carrying out silica gel column chromatography on the supernatant, carrying out elution by using a petroleum ether-ethyl acetate mixed solution as a mobile phase, and collecting the resulting elution fraction to obtain the tar extract. In the method, the tar is extracted from the discarded cigarette butt as a raw material. Through the microwave-assisted extraction and separation by the silica gel column chromatography, harmful substances in the tar of the cigarette butt are removed, and the components with aroma characteristics are retained, and the tar extract is applied to a low-end cigarette.
