Medical needs lay the foundation
Flavonoids are not rare in plants, and dihydroquercetin is no exception. In 1936, Hungarian scientists discovered an antioxidant that can increase the strength of capillaries and normalize the permeability of capillaries. Scientists classified it as a vitamin P family, and later extracted this substance from plants such as yew, yellow fir, and larch. With the improvement of extraction technology, people have also found the existence of dihydroquercetin in plants and fruits, but its content is extremely limited, which is difficult to meet the needs of biological effects and industrial extraction. Larch has become the "only" development channel.
Traditional application
China's traditional Chinese medicine has a long history. As early as the "Huangdi Neijing", there are records of the pharmacological value of pine trees, which are listed as the best medicine for treating diseases and longevity; the medicinal value of pine trees is clearly recorded in the "Compendium of Materia Medica" of the Ming Dynasty: " Pine is a tree of hundreds of trees. Its leaves, bark, roots and ointment are mainly used to treat wind pain, hair growth, strengthen the spleen and stomach, soothe the five internal organs, strengthen yang and nourish the middle, prevent hunger and prolong life, strengthen teeth after long-term use, maintain the appearance of the skin, and improve the skin. "Modern medical research shows that dihydroquercetin has significant antioxidant properties and has important applications in the fields of tumor treatment, radiation protection, improvement of myocardial function, and maintenance of metabolic systems.
Modern application
Although dihydroquercetin is famous, its modern application has only a history of more than ten years. The content of dihydroquercetin is relatively rich in plants such as larch and Douglas fir, with a content of about 0.3%-5.7%, but its extraction is extremely difficult, which directly curbs the "throat" of industrial application. Most of the tree species rich in dihydroquercetin are located in Russia and the United States. The strong resource base has also created the core position of these two regions in this field. In 2003, dihydroquercetin was added to the drug registration book by Russia. In 2006, dihydroquercetin was successfully extracted from the roots of larch in Siberia, and the industrial production of medicines began, and it was included in the pharmacopoeia; in the United States, dihydroquercetin is included in the FDA list and is produced as vitamin P for pharmaceutical production.
