A kind of ethanol extract of burdock root and its application in tobacco

Abstract

The invention discloses burdock root ethanol extract and the application thereof in tobacco. The preparation process of the burdock root ethanol extract comprises the following steps that a, burdock root is subjected to impurity removal and is cleaned and sliced; b, the slices are dried under the temperature of 30-60 DEG C; c, the slices are smashed to realize the mesh of 10-100; d, ethanol is added to the smashed burdock root; e, the smashed burdock root is subjected to ultrasonic extraction for 45-75 minutes; f, the smashed burdock root is filtered, and filtrate is kept; g, the filtrate is concentrated, the volume after concentration is one seventh to one fifth of the volume before concentration, the burdock root ethanol extract is prepared and stored in the normal temperature. The application of the burdock root ethanol extract in tobacco comprises the following steps: a, the burdock root ethanol extract is sprayed to tobacco shreds, the weight of the concentrated solution is 0.1%-0.2% of the weight of the tobacco shreds; b, the tobacco shreds are processed into cigarette finished products. The burdock root ethanol extract and the application thereof in tobacco have the beneficial effects that the smoking quality of the cigarettes is improved under the condition that the original property of the cigarettes is not changed.

Description

technical field

[0001] The invention relates to a plant extract and its application in tobacco, in particular to a burdock root ethanol extract and its application in tobacco. Background technique

[0002] Burdock is a biennial herb of Compositae. It is a good homologous plant for medicine and food. It contains a variety of biologically active substances and is widely used in the pharmaceutical industry. , antibacterial and anti-inflammatory effects, etc. According to reports, the fructan extracted from burdock root has a strong antitussive effect according to activity studies, which is equivalent to the non-narcotic antitussives commonly used in clinical practice. The domestic research on burdock is mainly in chemical composition determination, medical use, comprehensive processing and utilization, etc.
