Apple polyphenol halitosis-removing mouthwash and preparation method thereof

The invention discloses apple polyphenol halitosis-removing mouthwash and a preparation method thereof. Apples are used as a main raw material, apple polyphenol monomers such as chlorogenic acid, catechin, phlorizin and anthocyanin are obtained through separation by using a high-speed countercurrent chromatography, and then the apple polyphenol halitosis-removing mouthwash is prepared from the following components in percentages by mass: 0.05-0.08% of chlorogenic acid, 0.07-0.1% of catechin, 0.1-0.2% of phlorizin, 0.06-0.08% of anthocyanin, 1-3% of xylitol, 0.1-0.2% of potassium sorbate, 0.02-0.04% of vitamin C, 0.1-0.3% of table salt, 5-8% of ethanol, 8-10% of glycerin and the balance of deionized water, wherein the total percentage is 100%. Apple polyphenol is separated by using the high-speed countercurrent chromatography for the first time, the obtained polyphenol monomers are high in yield and high in purity, and the obtained mouthwash has an obvious effect of removing halitosis, can keep fresh breath fo
