Table 1.

IC₅₀ values of Carpinus tschonoskii leaf (CTL) extract and tellimagrandin I (TI) on each bioactivity, including free radical scavenging activity, inhibitory activity of NO production, IL-6, IL-8 and 5α-reductase

Samples		IC₅₀
Samples		radical scavenging activity	inhibitory activity of NO	inhibitory activity of IL-6	inhibitory activity of IL-8	inhibitory activity on 5α-reductase
(μg mL⁻¹)	CTL	31.42 ± 0.73^a	5.98 ± 0.33^a	14.20 ± 7.07^a	7.46 ± 2.60^a	197.81 ± 1.92^a
(μg mL⁻¹)	Positive Control	14.67 ± 2.90^b	1.48 ± 0.98^b	2.98 ± 1.47^b	0.74 ± 0.09^b	40.65 ± 9.56^b
Compound (μM)	TI	12.88 ± 0.30^a	5.44 ± 1.84^{a, b}	6.82 ± 2.37^a	0.56 ± 0.56^a	331.75 ± 14.62^a
Compound (μM)	Positive Control	9.13 ± 0.49^b	2.35 ± 1.14^b	6.68 ± 1.86^a	0.56 ± 0.52^a	45.98 ± 15.40^b

The results were expressed as mean ± standard deviation (SD) of triplicate experiments. (n = 3) ^a-bin the same column are significantly different, p < 0.05. Positive control of free radical scavenging experiment is ascorbic acid, positive control of inhibitor activity of NO production is L-NMMA, positive control of inhibitory activity of IL-6 and IL-8 is EGCG, positive control of inhibitory activity of 5α-reductase is Finasteride
