TL;DR: As a general rule the ethanol extracts of plants belonging to the Verbenaceae family showed lower EC50 values than the other plant extracts, among the partitions, the more polar ones (ethyl acetate and n‐butanol) are those that generally have higher antioxidant activity (AA).

TL;DR: A high carvacrol content in the essential oil determines the plant’s suitability for the preparation of oregano condiment, and the existence of a new chemotype is proposed for this species.

TL;DR: The chemical and pharmacological data of Lippia alba are in agreement with the ethnobotanical survey, and the chemical composition and antimicrobial activity of their essential oils was investigated.

TL;DR: This paper proposes strategies of solvent system selection for the isolation of flavonoids by CCC, based on data from the literature, plus incorporation of own practical experiences, to show the versatility of this technique.

TL;DR: Results showed that both extracts contributed to a higher in vivo photoprotection when compared to the formulation without extract (SPF 13), this result could be attributed to the antioxidant activity of the plant extracts that act by capturing reactive oxygen species.
