Abstract

The invention provides a tobacco active ingredient, an extraction method and an application thereof, and belongs to the technical field of tobacco product processing and extraction. Through pretreating tobacco raw materials, and sequentially carrying out normal temperature extraction on the pretreated tobacco raw materials, High temperature extraction, methanol extraction three times, and purifiedwater using high polar solvent, methanol as the extraction solvent, through the use of different extraction solvents and different extraction conditions, can ensure that the tobacco active ingredients in tobacco raw materials can be fully extracted, improve the extraction content of tobacco active ingredients. It is found that the target component has antibacterial and anti-tumor functions and isa low toxicity product. Therefore, it has the development potential of antibacterial and anticancer drugs, and provides a theoretical basis for new drug research and development.

Description

technical field [0001] The invention relates to the technical field of tobacco product processing and extraction, in particular to a tobacco active component, an extraction method and an application thereof. Background technique [0002] Tobacco, also known as fairy grass, is a traditional Chinese medicinal material. Its inorganic components include water and mineral elements; organic components mainly include sugars, alkaloids, heterocyclics, pigments, phenols, terpenes, organic acids, lipids Substances, alcohols, aldehydes and ketones, etc. Among them, the organic components in tobacco have various functions such as antibacterial, antiviral, antitumor, antioxidant activity, and scavenging free radicals in the body. [0003] At present, in order to realize the extraction of active components of tobacco, supercritical extraction, Soxhlet extraction, and ultrasonic extraction are generally used. Absolute ethanol, n-hexane, acetone, ethyl acetate, petroleum ether, and dichlo...
