Since the 1990s, the international academic community has begun to pay attention to carbon glycoside flavonoids, which is the latest research frontier. There are four kinds of carbon glycoside flavonoids in bamboo leaves, namely orientin, isoorientin, vitexin and isovitexin, and their chemical structures are shown in the right picture. Bamboo leaf flavonoids is the first plant flavonoids preparation in China, which has the characteristics of local resources and independent intellectual property rights in China. Bamboo flavone produced by patented technology is a multi-component synergistic biological antioxidant. In addition to flavonoids, its components also include phenolic acids, anthraquinone compounds, aromatic components and trace elements such as manganese, zinc and tin, and their isomorphism forms the basis of extensive physiological and pharmacological activities.
