The invention discloses a ramie fiber cigarette filter tip. A filter element of the ramie fiber cigarette filter tip consists of ramie fiber and acetate fiber, wherein the ramie fiber accounts for 10 percent to 50 percent of the weight of the filter element. The invention also discloses a preparing method of the ramie fiber cigarette filter tip. According to the preparing method, the ramie fiber is subjected to ultrasonic treatment for 40 to 60 minutes under the conditions that the water temperature is 50 to 70 DEG C and the ultrasonic frequency is 25 to 30khz; then, steam explosion is performed; next, the ramie fiber is put into an NaOH solution with the mass percent being 1 to 5 percent; the stirring is performed at 40 to 75 DEG C for reaction for 1 to 3 hours; and then, filtering, drying and forming are sequentially performed. The prepared ramie fiber cigarette filter tip has good air permeability and can effectively filter out harmful ingredients in cigarette smoke gas; after the ramie fiber is subjected to alkali treatment and esterification treatment, the adsorption capacity and the selective adsorption characteristics of the ramie fiber can be enhanced; and the ramie fiber can be used for cigarette filter tips with different pertinences.
