Abstract
Two new A, D-seco-limonoids, accorded the trivial names, uguenensene (4) and uguenensone (5) and a new C-7 prenylated flavonoid, uguenenprenol (8) were isolated from Vepris uguenensis (Rutaceae). In addition, eleven known compounds, niloticin (1), chisocheton A (2), kihadalactone A (3), limonyl acetate (6), methyl uguenenoate (7), 7-O-methylaromadenrin (9), flindersiamine (10), 8α,11-elemodiol (11), tricoccin S13 acetate, skimmianine, and lupeol were isolated. Antioxidant activity of the isolated compounds showed that 8 and 9 were good antioxidant agents. Significantly high antioxidant activity was also exhibited by 8α,11-elemodiol (11). The two new limonoids fit nicely into a biosynthetic scheme with other limonoids isolated from the plant.
