Abstract
Seven known (1-7) and one new compound (8) were isolated and identified from the stem of Olea ferruginea. The species has been recognised as a new source for six of the known metabolites (1, 3, 4, 5, 6, and 7). Based on detailed spectroscopic analyses, these compounds were identified as scopoletin (1), 8-ketosetosterol (2), (+)-cycloolivil (3), (+)-africanal (4), isovanilic acid (5), hydroxytyrosol acetate (6), vanillic acid (7), and cycloolivil A (8). The crude extracts and purified compounds were analysed for their Leishmanicidal, anti-glycation, anti-cancer, and anti-inflammatory activities. n-Hexane fraction was found to be the most active (among all the fractions), against Leishmania parasites, exhibiting 97.85% inhibition at 15 μg/mL. However, none of the extracts showed any significant anti-glycation or anti-cancer potential, all the fractions, except the aqueous layer, displayed moderate to low anti-inflammatory activity. Compound 1 was found to have strong anti-inflammatory activity, exhibiting 96.7% stimulation at 25 μg/mL.
