Theaflavins are bioflavonoids that are produced when green tea ferments and changes into black or oolong tea. Bioflavonoids are effective antioxidants found in many plants. A group of flavonoids in green tea are known as catechins,  which are quickly absorbed into the body and are thought to contribute to some of the potential health benefits of tea. Theaflavin also can lower the level of LDL cholesterol and raise the level of HDL cholesterol.
