Water-soluble dihydromyricetin nano system as well as preparation method and application thereof

The invention relates to a water-soluble dihydromyricetin nano system. The preparation method of the water-soluble dihydromyricetin nano system comprises the following steps: a, uniformly mixing o-cymene-5-ol and dihydromyricetin to obtain an anti-inflammatory active mixed system; b, adding composite lipid and an emulsifier into the anti-inflammatory active mixed system, and carrying out ultrasonic dissolution; c, after ultrasonic dissolution, deionized water is added, ultrasonic stirring is conducted to be uniform, and the water-soluble dihydromyricetin nano system which is stable colorless or light yellow transparent colloid is obtained. The nano system solves the problems of poor water solubility, poor stability and the like of the anti-inflammatory active ingredient dihydromyricetin, and can be used as an anti-inflammatory active ingredient to be applied to preparation of anti-inflammatory acne-removing cosmetics. 本发明涉及一种水溶性二氢杨梅素纳米系统，其制备方法包括以下步骤：a将邻伞花烃-5-醇和二氢杨梅素混合均匀，得抗炎活性混合体系；b向上述抗炎活性混合体系中，加入复合脂质和乳化剂，超声溶解
