Three new diterpenoids, demethylfruticuline B (1), 20-hydroxyfruticuline B (2), and 6-hydroxyisofruticuline A (3) were isolated from the leaves of Salvia lachnostachys Benth, together with five known compounds: fruticuline B (4), fruticuline A (5), demethylfruticuline A (6), heterobetulinic acid (7), and maslinic acid (8). The known compounds 7–8 are being reported for the first time in this species. Compounds 1 and 4–6 were tested for antioxidant activity using the ORAC-FL method, and the antioxidant capacity was measured as relative trolox equivalent. All compounds were active, with values of relative trolox equivalent varying between 1.20–2.42. The most active compound was demethylfruticuline B (1). [ABSTRACT FROM AUTHOR] |
