| Sample | FRS50 (μg/mL) | |
|---|---|---|
| DPPH FRS Activity | ABTS+• FRS Activity | |
| KL | 437 ± 10.9 b | 121 ± 6.6 b |
| KST | 1,136 ± 14.2 e | 455.3 ± 17.1 e |
| KR | 582 ± 16.4 c | 138.0 ± 2.7 c |
| KSP | 755 ± 8.6 d | 341.7 ± 1.4 d |
| Control | 17 ± 0.3 a | 5.5 ± 1.0 a |
Each value in the table is represented as mean ± SD (n = 3). Means not sharing the same letter are significantly different (LSD) at p < 0.05 probability level in each column. KL: Kudzu leaf extract; KST: Kudzu stem extract; KR: Kudzu root extract; KSP: Kudzu sprout extract.
