Table 1.

Total phenolic content (TPC), total flavonoids content (TFC), DPPH, ABTS, and FRAP (ferric reducing-antioxidant power) were used to evaluate the methanolic (Ht MeOH) and aqueous extract (Ht Aq) of H. taltalense.

Extract	TPC	TFC	IC50 DPPH	IC50 ABTS	FRAP
Ht MeOH	1283 ± 175	743 ± 51	400 ± 2	66 ± 1	4067 ± 262
Ht Aq	75 ± 2	261 ± 3	595 ± 3	40 ± 0	2503 ± 435

The results are expressed as TPC in mg gallic acid equivalent/g dry extract, TFC in mg quercetin equivalent/g dry extract, IC₅₀ DPPH and ABTS in μg/mL, and FRAP in mg trolox equivalent/g dry extract. Data are the average standard error of the mean (SEM) of 3 independent experiments.
