T
he consumption of infusions and herbal teas has always been an important part of folk medicine. As a result, the study of their
(bio)chemical properties and composition is important. In this work, the phytochemical profile and antioxidant activity of
Rosa
rubiginosa
and
Fraxinus oxycarpa
herbal teas are reported for the first time. The chemical profiles were evaluated by high-performance
liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI-MS
n
), as well as by their total phenolic
and flavonoid content. The highest percentage of compounds in the extracts of
Rosa rubiginosa
corresponded to phenolic acids
and flavonoids, whereas coumarins and secoiridoids were dominant in
Fraxynus oxycarpa
extracts. The antioxidant activities were
evaluated by the
in vitro
antioxidant assays DPPH and ABTS. Comparing both samples,
Fraxinus oxycarpa
presented the highest
antioxidant activity. This study can contribute to a better understanding of the nutritional and health-promoting properties of
uncommon herbal teas.
