Abstract
Three new iridoids, valeriandoids D–F (1–3), have been isolated from the roots of Valeriana jatamansi. Structure elucidation, especially the positions of the acyloxy groups, and complete 1H- and 13C-NMR assignments of these new compounds were carried out using one- and two-dimensional NMR measurements, including 1H- and 13C-NMR, DEPT-135, 1H–1H COSY, HMQC, HMBC, and HR-ESI-MS experiments.
