Flavonoids was isolated from canavalia maritime by accelerated solvent extraction (ASE) coupled with high-speed counter-current chromatography (HSCCC). The antioxidant activities of flavonoids were investigated in vitro and evaluated by IC50. The results indicated that flavonoids possessed obvious reducing power and significant inhibitory effects on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical and superoxide radical. These results suggest that canavalia maritime flavonoids could be a suitable natural antioxidant for humans.

Equilibrium studies with low-boiling hydrocarbon fractions and crude mustard gas indicate that the latter can be extracted to give product purities of approximately 92.5% with 95% recovery. These values have been verified in the operation of a pilot plant for continuous counter-current extraction of crude mustard gas.
