Formula Structure
What is Dihydromyricetin?
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. It was found that the
dihydromyricetin–lecithin complex was an effective scavenger of DPPH radicals with an
IC50 of 22.60 μg/mL. In the Rancimat antioxidant test using lard oil as substrate, the performance of the complex with protection factor of 6.67 was superior to that of butylated hydroxytoluene with protection
factor of 5.54.
