Table 3.
The half-maximal inhibitory concentration (IC50) values of lipid peroxidation, AOPP and AGEs of gallic acid, red and white N. nucifera petal with different methods of extraction.
| Sample | Extraction | IC50 (µg/mL) | ||
|---|---|---|---|---|
| LPO | AOPP | AGEs | ||
| Red | Aqueous | 0.10 ± 0.00 a | 2.66 ± 0.49 a | 0.55 ± 0.24 |
| 95% ethanol | 0.17 ± 0.10 a | 11.88 ± 0.80 b | 1.00 ± 0.70 | |
| White | Aqueous | 0.05 ± 0.01 b | 0.35 ± 0.07 c | 1.07 ± 0.93 |
| 95% ethanol | 1.35 ± 0.60 c | 27.19 ± 6.00 d | 1.23 ± 1.35 | |
| Gallic acid | 0.11 ± 0.01 a | 4.21 ± 0.07 e | 1.05 ± 0.12 | |
a,b,c,d,e The variables with the different letters indicate significant differences between groups in column data at p < 0.05 (LPO and AGEs analyzed by One-way ANOVA followed by Tukey’s test; AOPP were analyzed using Mann-Whitney tests to analyze the differences between groups). The variables with the same letter are not statistically significant.
