A method for producing sclareol by fermentation of cigar tobacco flower buds is provided, including: mixing cigar tobacco flower buds with deionized water, sterilizing and adding edible yeast, then fermenting at 25-30° C. and 100-300 rpm/min for 24-30 h. This method uses cigar tobacco flower buds as the sole raw material, without adding additional nutrients, and only ferments tobacco flower buds with edible yeast to synthesize sclareol. Meanwhile, this method has extremely high synthesis efficiency.

The present disclosure discloses a tobacco leaf foliar spraying substance for reducing harmful ingredients in cheroot, a method for reducing carcinogenic components in flue-cured tobacco leaves and flue-cured tobacco shreds. The tobacco leaf foliar spraying substance contains a lotus leaf extract, the harmful chemical ingredients comprise N-nitrosonornicotine, 4-(N-methyl-nitrosamine)-1-(3-pyridinyl)-1-butanone, N-nitrosoanabasine and N-nitrosoanatabine. Foliar spraying is performed on a fertile field by using the lotus leaf extract before tobacco leaves are harvested and modulated, which not only significantly promotesagronomic characters and economic traits of tobacco and alleviates tobacco leaf browning but also effectively reduces harmful chemical ingredients unique to tobacco leaves, such as nitrosamine and nicotine.
