Abstract: Dihydroquercetin is an important flavonoid compound in nature, which mainly exists in the root of Larix gmelinii in alpine zone. It has been widely used in food, industry and medicine fields due to its good biological activities such as anti-oxidation and anti-tumor. However, at present, the industrial production of dihydroquercetin still depends on traditional plant extraction, which is scarce in raw materials, difficult to extract and low in yield, thus hindering the advancement of its industrial application. Based on this, the research progress of chemical structure and properties, molecular mechanism of biosynthesis, biological activity and production technology of dihydroquercetin were mainly reviewed, and the related research trends in dihydroquercetin in the future were prospected, so as to provide theoretical references for the biosynthesis research on dihydroquercetin in the future.
