Abstract

The invention discloses plant extract-containing tobacco. The plant extract is one or more of licorice total flavonoids, ginkgo leaf extract, epimedium herb total flavonoids, astragalus total saponins, proanthocyanidins and dwarf lilyturf tuber total saponins. The plant extract-containing tobacco is characterized in that: the plant extract content is 0.01 to 0.1 percent; the plant extract has the effect of eliminating radicals, polycyclic aromatic hydrocarbon and nitrosamine compounds serving as smoke harmful substances in vitro. After the plant extract is added into the tobacco, cytotoxicity of human bronchial epithelial cells caused by smoke of cigarettes prepared by the tobacco can be reduced and harm of smoke to people can be effectively reduced. In addition, the invention also provides a preparation method for the tobacco.

Description

technical field [0001] The invention relates to the field of tobacco and its preparation, in particular to a low-harm tobacco product added with plant extracts and its preparation. Background technique [0002] The components in cigarette smoke are extremely complex, which not only pollutes the atmosphere, but also poses certain hazards to human health. Current studies believe that the main harmful substances in smoke are polycyclic aromatic hydrocarbons, volatile nitrosamine compounds and free radicals, etc.: polycyclic aromatic hydrocarbons and nitrosamine compounds are strong carcinogens; free radicals can directly and indirectly attack cell components , is an important cause of various diseases, and free radicals can continue to polymerize at high temperatures to form different polycyclic aromatic hydrocarbons, which endanger human health. [0003] my country's tobacco industry has conducted a lot of research on reducing these harmful components of smoke, and strives to...
