Abstract

Chemical investigation of Esenbeckia almawillia afforded, in addition to a known furocoumarin and a cinnamaldehyde derivative, three new quinolone alkaloids, 8-methoxy-1-methyl-2-pentyl-, 8-methoxy-1-methyl-2-hexyl- and 8-methoxy-1-methyl-2-heptyl-4-quinolone, and a cinnamic acid derivative, 3-methoxy-4,5-methylenedioxycinnamic acid methyl ester. All compounds were elucidated through analysis of spectroscopic data.
