Key Points

This research aimed to characterize the phenolic metabolomes of two Peruvian medicinal plants and assess their antioxidant capacity.
Conducted solid-liquid extraction of plant samples.
Analyzed extracts using Folin-Ciocalteu, FRAP, and ABTS assays.
Employing LC-ESI-QToF based metabolomics to profile compounds.
Performed morphological characterization through light microscopy.
Inca muña (C. bolivianum) showed higher phenolic content (201 mg GAE/200 mL) compared to muña (M. mollis) at 134 mg GAE/200 mL.
Inca muña exhibited superior antioxidant capacity in FRAP and ABTS assays.
Fifty-one phenolic compounds were identified, with distinct profiles between the species.
Muña was notable for phenylacetaldehyde, while inca muña had higher levels of cudraflavone and naringenin.
