production was investigated in a cell-free xanthine/xanthine oxidase [O.
generated in the xanthine/xanthine oxidase system was significantly decreased by EVI-1, EVI-2, and EVI-4 (10-300 [micro]g/ml), whereas EVI-3 up to 300 [micro] g/ml and EVI-5 up to 100 [micro]g/ml had no effect (Fig.
formation induced by xanthine/xanthine oxidase system was measured.
05 <2 First row shows the results in xanthine/xanthine oxidase and second row shows the results in AHP/xanthine oxidase system.
In the xanthine/xanthine oxidase
system, EAF was more effective at both inhibiting xanthine oxidase activity and inhibiting NBT reduction.
Furthermore, effects of structural modification of silybin (1) in oxidative processes induced by xanthine/xanthine oxidase (measured by uric acid and [O.
production was induced in xanthine/xanthine oxidase system, only silybin (1) inhibited uric acid formation (Fig.
Superoxide anion, generated by the xanthine/xanthine oxidase
system, converted nitroblue tetrazolium to formazan that had maximum absorption at 560 nm.
wrightii showed very strong scavenging action for superoxide anion generated from xanthine/xanthine oxidase
