Fig. 8. The protective actions of barbaloin on sulfhydryl groups against oxidative damage in erythrocyte membranes. Results are expressed as nmol SH/mg protein. Data represent mean values ± S.D. from four independent experiments. C: control without the test compound, T: 1 mM Trolox. Results are compared against the control with oxidative damage by one-way ANOVA followed by Dunnett's test. *, P <0.05; ***, P <0.001.
