From the dried roots of Cephaelis acuminata, five ipecac alkaloids, neoceph
aeline, 7'-O-demethylcephaeline, 10-O-demethylcephaeline, 2'-N-(1 "-deoxy-1
"-beta-D-fructopyranosyl)cephaeline and 2'-N-(1 "-deoxy-1 "-beta-D-fructop
yranosyl)neocephaeline, were isolated, along with emetine, cephaeline, psyc
hotrine, protoemetine, 9-demethylprotoemetinol and isocephaeline. Structure
s were determined by spectroscopic and chemical means. (C) 1999 Elsevier Sc
