Iridoids and sesquiterpenoids from the roots of Valeriana jatamansi Jones
2015
Three new iridoids, jatamanvaltrates R-S (1-2) and jatamanin Q (3), as well as three new sesquiterpenoids, valeriananoids D-E (4,5) and clovane-2 beta-isovaleroxy-9 alpha-ol (6), together with nine known compounds were isolated from the roots of Valeriana jatamansi Jones. Compound 2 was the first reported iridoid with fatty acid esters in the Valerianaceae family. The structures of new compounds were established on the basis of extensive spectroscopic analysis. Moreover, all the isolates were evaluated for inhibitory activity on acetylcholinesterase (AChE). (C) 2015 Elsevier B.V. All rights reserved.
