The present study aimed to investigate vitro the cytotoxic, photoprotective antioxidant activities of ten taxa; Melissa officinalis subsp. altissima (Sm.) Arcang., Rosmarinus L., Salvia Sideritis cypria Post, S. euboea Heldr., perfoliata L. perfoliata, scardica Griseb., sipylea Boiss., S...

Many invasive species are considered competitively superior to native species, with the strongest competition expected in species with similar niches and/or in closely related species. However, competition outcome is strongly context-dependent as competitive strength varies along environmental gradients, and life stages, and also depends on abundances. To explore the importance of these factors...

The methanolic extract from the barks of the medicinal plant Qualea parviflora (Vochysiaceae) was fractionated by column chromatography over silica gel followed by gel permeation over Sephadex LH-20 to give 3,3'-di-O-methylellagic acid-4-O-beta-D-glucopyranoside (1), 3-O-methylellagic acid-4'-O-alpha-L-rhamnopyranoside (2), 3,3',4-tri-O-methylellagic acid-4'-O-beta-D-glucopyranoside (3), and 3,...
