Patent number: 11968983Abstract: 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.Type: GrantFiled: June 17, 2023Date of Patent: April 30, 2024Assignee: HUBEI INSTITUTE OF TOBACCO SCIENCEInventors: Chunlei Yang, Jinpeng Yang, Jun Zhou, Mei Yang, Yong Yang, Jun Yu, Zongping Li, Xiongfei Rao, Guangjiong Qin, Baoming Qiao, Ruoshi Bai, Yanjun Ma, Xianbao Deng, Wenzhang Qin, Kaixiao Fan, Candong Deng, Yongle Wei, Youlun Fan
