Table 2.

Antioxidant assays and total phenolic and flavonoids content of ZpRe from Z. punctata.

Phenolics Content ZpRe
Total phenolics (mg GAE/g ZpRe) 391.40 ± 2.18
Flavonoids (mg QE/g ZpRe) 313.18 ± 3.10
Antioxidant Assay
DPPH (EC50 in µg ZpRe/mL) 25.72 ± 1.51
FRAP (mg TE/g ZpRe) 1.74 ± 0.13
TEAC (mg TE/g ZpRe) 1.25 ± 0.01
Percentage LP (at 100 µg ZpRe/mL) 70.14 ± 2.26
Percentage LP (at 100 µg catechin/mL) 74.14 ± 1.25

No significant differences were found between the three samples. ANOVA (analysis of variance) followed by Dunett’s comparison test was used (significance p < 0.05). DPPH: (2,2-diphenyl-1-picrylhydrazyl; TEAC: trolox equivalent antioxidant activity assay; FRAP: ferric-reducing antioxidant power assay.
