Complete NMR assignment and absolute configuration of feronielloside, a new acetylcholinesterase inhibitor from Feroniella lucida.
Feronielloside (1), a new furanocoumarin glycoside, was isolated from roots of Feroniella lucida. The structure of 1 was elucidated by combined spectroscopic and chemical analysis. The absolute configuration of the chiral center in geranyl-derived side chain was confirmed by modified Mosher's method. Feronielloside inhibited acetylcholinesterase with IC(50) value of 24.7 mM.
