Abstract:
From the capitula of Helichrysum compactum, the flavonoids apigenin, kaempferol, luteolin, naringenin, 3,5-dihydroxy-6,7,8-trimethoxyflavone, kaempferol-3-O-glucoside, luteolin-7-O-glucoside and luteolin-4',7-di-O-glucoside and from the leafy stems apigenin, kaempferol, luteolin, quercetin, apigenin-7-O-glucoside, luteolin-7-O-glucoside, and quercetin-3-O-glucoside were isolated. Extracts of the capitula of H. compactum show antioxidant activity by inhibition of lipid peroxidation and also show antibacterial activity.
