A new acylated iridoid, valejatadoid H (1), along with fourteen known compounds, were obtained from the n-BuOH extract of the roots and rhizomes of Valeriana jatamansi, and their structures were elucidated by various spectroscopic methods.Among them, compounds 8, 11 and 13 exhibited potent inhibition on NO production, with IC 50 values of 4.21, 6.08 and 20.36 μM, respectively. In addition, compounds 14 and 15 showed anti-influenza virus activities, among which compound 14 exhibited significant effect with an IC 50 value of 0.99 μM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
