Natural extract added into cigarettes, extracting method thereof and cigarettes

Abstract

The invention discloses a natural extract added into cigarettes, an extracting method thereof and cigarettes, which aim at solving the technical problem of reducing harms to the human body from the cigarettes. The natural extract can be prepared by adopting the following steps: crushing dried stem leaves of ampelopsis grossedentata, refluxing by ethanol, decompressing and concentrating at 0.05MPaand 80 DEG C for 2 hours, adding water, heating, dissolving, filtering, adding macroporous resin columns, eluting by ethanol, and recrystallizing eluant at 0-10 DEG C to obtain 99 percent of natural extract of dihydromyricetin. The cigarettes contain the natural extract of the dihydromyricetin, which accounts for 0.01-10 percent of cut tobaccos in weight percent. Compared with the prior art, the invention keeps the original taste and style of the cigarettes, can reduce the contents of nitrosamine, CO, phenol and crotonic aldehyde in cigarette smoke, and releases the adverse reactions of cough,asthma, phlegm stasis, throat obstruction, and the like caused by smoking.

Description

technical field [0001] The invention relates to an extract added to cigarettes to reduce the harm of cigarettes and an extraction method thereof, a cigarette added with the extract, especially a natural extract and its extraction method, and a cigarette added with the extract. Background technique [0002] In recent years, my country's tobacco industry has done a lot of work in the field of cigarette harm reduction technology research and application, and achieved certain results. A batch of practical additive products that reduce the harmful components of cigarette smoke have been developed and applied in cigarettes. However, the current level of my country’s harm reduction products cannot fully meet the needs of my country’s current development of Chinese-style cigarettes. There is a lack of relatively mature selective harm reduction products with high selectivity, good stability, and strong industrial applicability. Since 2005, the National Tobacco The Monopoly Bureau org...

Problems solved by technology

However, the current level of my country’s harm reduction products cannot fully meet the needs of my country’s current development of Chinese-style cigarettes. There is a lack of relatively mature selective harm reduction products with high selectivity, good stability, and strong industrial applicability. Since 2005, the National Tobacco The Monopoly Bureau organized the research work on the cigarette hazard index system, and finally screened out CO, HCN, NNK, NH 3 , benzo[α]pyrene, phenol and crotonaldehyde to characterize the biohazardousness of mainstream cigarette smoke
