Three phenylethanoid glucosides of unusual structure from Chirita sinensis (Gesneriaceae).
From Chirita sinensis (Gesneriaceae) was isolated six phenylethanoid glucosides, namely the previously known positional isomers plantainoside A, calceolarioside A and calceolarioside B together with three new compounds named chiritoside A, B and C. It was proved by analysis of the NMR data that the chiritosides were the 4"-O-beta-glucopyranosyl-derivatives of the first three compounds.
