Aitchisonides A and B, new iridoid glucosides from Aitchisonia rosea

Abstract

Aitchisonides A (1) and B (2), new iridoid glucosides, were isolated from the n-butanolic fraction of Aitchisonia rosea along with deacetylasperulosidic acid (3) and nepetanudoside B (4), which were reported for the first time from the genus Aitchisonia. Their structures have been assigned on the basis of spectral analysis including ¹H and ¹³C NMR spectra and by DEPT, 2D COSY, NOESY, and HMBC experiments.
