    Author: Xu J, Guo Y, Jin DQ, Zhao P, Guo P, Yamakuni T, Ohizumi Y.
    Journal: J Nat Med; 2012 Oct; 66(4):653-7. PubMed ID: 22331424.
    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 (1)H- and (13)C-NMR assignments of these new compounds were carried out using one- and two-dimensional NMR measurements, including (1)H- and (13)C-NMR, DEPT-135, (1)H-(1)H COSY, HMQC, HMBC, and HR-ESI-MS experiments.
