title: 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 (1)H and (13)C NMR spectra and by DEPT, 2D COSY, NOESY, and HMBC experiments.
