cut into slices, dried and smashed; b. the Chinese yam is extracted and condensed through ethyl 
alcohol with the certain concentration to obtain Chinese yam 
alcohol extraction liquid; c. material residues after 
alcohol extraction are further extracted through water; d. after 
water extraction liquid is filtered and condensed, ethyl alcohol is added to the 
water extraction liquid, precipitating, standing and filtering are conducted, and precipitates are dried to obtain Chinese yam crude 
polysaccharide; e. deproteinization and purification are conducted. When being applied in a cigarette perfuming link, Chinese yam alcohol extraction liquid can improve perfuming quality, cover sundry flavors, increase clean 
aroma and sweet 
aroma, ensure that 
smoke is more delicate, and improve 
cigarette smoking and absorbing comfort. After being dissolved in water and used as cigarette material liquid, the Chinese yam crude
