Introduction: Dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) is a natural antioxidant with good prospects. The physicochemical properties of dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) were analyzed by ultraviolet–visible spectrometry, infrared spectrometry, scanning electron microscopy, differential scanning calorimetry, Xray diffractometry. The result showed that dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) and lecithin inthe complex were combined by non-covalent bond, did not form a new compound and the solubility of dihydromyricetin in n-octanol was significantly enhanced. Functions: Dihydromyricetin belong to Flavonoids, Has the high bio-logical activity. Often as food-oxidants and preservatives, And has the removing free radicals, diminish inflammation, relieve a cough, fall fat, protect liver functions.
