Assays	Rhizoma Cibotii	BHA	Trolox
DPPH	44.26 ± 0.62^a,b	2.03 ± 0.28	4.02 ± 0.71
ABTS	19.84 ± 0.31^a,b	2.03 ± 0.28	1.49 ± 0.00
• O_2⁺	137.66 ± 2.90^a,b	2568.62 ± 11.78	799.11 ± 72.30
• OH	22.94 ± 0.90^a,b	26.39 ± 0.28	41.84 ± 3.79
Reducing power (Fe³⁺)	289.73 ± 46.17^a,b	34.14 ± 0.26	44.96 ± 0.60
Reducing power (Cu²⁺)	53.52 ± 1.51^a,b	5.74 ± 0.23	11.32 ± 0.09

All values were mean ± SD (n=3). Results were analyzed by ANOVA. Value with ^a significantly different from Trolox (P < 0.05); Value with ^b significantly different from BHA (P < 0.05). MERC, methanolic extract from Rhizoma Cibotii.
