Abstract Kosteletzkya virginica (K. virginica) is used for revegetation of salt-affected coastal tidal flats and as a raw material
of biodiesel. K. virginica root tuber, a biowaste with low economic value, is rich in bioactive compounds. This
study aimed to extract and identify flavonoids from K. virginica root tubers. The optimal extraction conditions
were 1/25 (w/v) solid/liquid ratio, 40% ethanol concentration at 40°C for 60 min. Under these conditions,
65.2 ± 3.7 mg/g total flavonoid content was extracted from the roots, which were collected from salinized soil
in late autumn of the third year. Antioxidant activity was evaluated through 1,1-diphenyl-2-picrylhydrazyl, More >
