Antioxidant activity of the lipidic extracts of BSF larvae (mean ± SD, n = 3).
| Samples | TBARS (EC50, mg/mL) | CAA (% inhibition of oxidation at 2 mg/mL) | |
|---|---|---|---|
| Acetone extractions | Maceration | >106.7 | 69 ± 6a |
| Reflux extraction | >106.7 | 62 ± 5a | |
| UAE | >133.3 | 62 ± 3a | |
| MAE | >106.7 | 77 ± 5a | |
| n-Hexane extractions | Maceration | >166.7 | 69 ± 9a |
| Reflux extraction | 11.6 ± 1.2a | 64 ± 5a | |
| UAE | 5.6 ± 0.1b | 75 ± 3a | |
| MAE | >106.7 | 64 ± 3a | |
| Positive control | 0.0058 ± 0.0006 | 95 ± 5 | |
Positive controls: Trolex (TBARS); Quercetin (CAA) at 0.3 μg/mL. UAE-ultrasound assisted extraction; MAE-microwaves assisted extraction. Statistical differences between extraction methods were assessed using ANOVA followed by Tukey's post-hoc test. In column, different letters (a, b) next to values indicate significant differences at p < 0.05.
