Phytochemistry. 1994 Sep;37(2):441-3. doi: 10.1016/0031-9422(94)85075-5.

Abstract

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.
