Abstract

The present invention discloses a trigonella foenum-graecum polysaccharide extraction purification method and applications of the trigonella foenum-graecum polysaccharide as a humectant in cigarettes. The extraction purification method comprises: crushing trigonella foenum-graecum, adding water to the obtained powder, placing into a flash extractor to extract, carrying out centrifugation separation on the obtained extraction solution, carrying out flash concentration on the separated supernatant, adding absolute alcohol to the concentrated solution, carrying out nature alcohol precipitation, standing, centrifugating to obtain a precipitate, removing proteins from the precipitate by using a Sevage method, carrying out flash concentration on the obtained trigonella foenum-graecum polysaccharide solution, carrying out alcohol precipitation, standing, centrifugating to obtain a precipitate, and carrying out freezing drying on the obtained precipite to obtain the refined trigonella foenum-graecum polysaccharide. According to the present invention, the extracted trigonella foenum-graecum polysaccharide can be adopted as the excellent performance tobacco additive so as to be used in cigarettes; with the extracted trigonella foenum-graecum polysaccharide, the extraction time can be shortened, the extraction efficiency can be improved, and the structural integrity and the biological activity of the polysaccharides are easily maintained; and with the application of the polysaccharide in the cigarettes, the irritation and the mixed gas of the cigarettes can be reduced, and the mellow and full feeling and the comfort of the cigarettes can be increased.

Description

technical field [0001] The invention relates to a plant extract and its application, in particular to a method for extracting and purifying fenugreek polysaccharide and its application as a humectant in cigarettes. Background technique [0002] Fenugreek (Trigonellafoenum-graecum L.), also known as alfalfa and fenugreek, is an annual herb. Fenugreek belongs to herbaceous aromatic plants and is mainly planted in Northwest China. Fenugreek is not only a vegetable, but also a medicinal material, which can nourish kidney yang, dispel cold and dampness, and treat cold diseases. The chemical components of fenugreek mainly include trigonelline, choline, and niacinamide. The application of fenugreek tincture and extract in cigarettes can suppress the pungent irritation of tobacco and cover up the miscellaneous gas. The relevant reports about fenugreek polysaccharides are currently mainly focused on the medical aspect, and the application in tobacco has not been reported yet. [0...
