Antimicrobial activity of dichloromethane and ethanol extracts five compounds: pinostrobin (I), pinocembrin (II), tectochrysin (III), galangin 3-methyl ether (IV) tiliroside (V) isolated from Lychnophora markgravii aerial parts against fifteen microorganisms was determined. The structures these compounds were elucidated based on ESI-MS NMR spectroscopic data. Both showed antimicrobial several tested microorganisms. Pinostrobin, the strongest antibacterial antifungal effects.
Three new diterpenoids, demethylfruticuline B (1), 20-hydroxyfruticuline (2), and 6-hydroxyisofruticuline A (3) were isolated from the leaves of Salvia lachnostachys Benth, together with five known compounds: fruticuline (4), (5), (6), heterobetulinic acid (7), maslinic (8). The compounds 7-8 are being reported for first time in this species. Compounds 1 4-6 tested antioxidant activity using ORAC-FL method, capacity was measured as relative trolox equivalent. All active, values equivalent...
