The content and profile of phenolic compounds of muña (Minthostachys mollis (Kunth) Griseb.) and inca muña (Clinopodium bolivianum (Benth.) Kuntze) leaves were studied. The total phenolic compounds in both species were similar, however antioxidant capacity was greater in inca muña. Phenolic extracts from inca muña and muña were analyzed by separating them in two main fractions: an aqueous fraction and an ethyl acetate fraction. A high concentration of phenolic compounds (74.5, 70.1%) and antioxidant capacity (72.0, 64.4%) were recovered in ethyl acetate fraction in comparison to aqueous fraction for both species. Analysis using high performance liquid chromatography with diode array detection (HPLC-DAD) was performed to characterize the phenolic compounds present in muña and inca muña leaves. The aqueous fraction for both species revealed the presence of hydroxycinnamic acids (caffeic and ρ-coumaric acid type); flavanones (eriodictyol type) and flavonols (rutine type) being the flavanones the most representative phenolic compounds. Ethyl acetate fractions were composed of hydroxycinnamic acids (caffeic acid type), flavanones (eriodictyol type) and flavones (apigenin type) being the hydroxycinnamic acids the most representative phenolic compounds. Differences in profile and concentration of phenolic compounds for both plants would indicate substantive differences between both species that belong to the same Lamiaceae family
