- Abstract
Three new chalcones, 3′-carboxymethyl-4,2′-dihydroxy-4′-methoxychalcone ( 1), (±)-4,2′,4′-trihydroxy-3′-[(3-hydroxy-2,2-dimethyl-6-methylenecyclohexyl)methyl]chalcone ( 2), and 2′′-hydroxyangelichalcone ( 3), were isolated from the aerial parts of Angelica keiskei (Umbelliferae) together with five known compounds, artocarmitin A ( 4), (+)- cis-(3′ R,4′ R)-methylkhellactone ( 5), (−)- trans-(3′ R,4′ S)-methylkhellactone ( 6), 3,4-dihydroxanthotoxin ( 7), and ( Z)- p-coumaryl alcohol ( 8). The known compounds 4 - 8 were identified from A. keiskei for the first time. The structures of 1 - 3 were elucidated by interpreting spectroscopic data including 1D- and 2D-NMR.
