Abstract
From Chirita sinensis (Gesneriaceae) was isolated six phenylethanoid g
lucosides, namely the previously known positional isomers plantainosid
e A, calceolarioside A and calceolarioside B together with three new c
ompounds named chiritoside A, B and C. It was proved by analysis of th
e NMR data that the chiritosides were the 4''-O-beta-glucopyranosyl-de
rivatives of the first three compounds.
