Iridoids from the Roots of Valeriana jatamansi

TLDR: Three new iridoids, jatamanins N-P (1, 3), along with the seven known iridiods 4-10, were isolated from the roots of Valeriana jatamansi as discussed by the authors.

Abstract: Three new iridoids, jatamanins N–P (1–3), along with the seven known iridiods 4–10, were isolated from the roots of Valeriana jatamansi. Compound 1 is an unusual iridoid bearing two epoxy bridges between C(3) and C(6) and between C(1) and C(10), forming a unique cage-like rigid skeleton. The structures of the new compounds were assigned on the basis of spectroscopic methods.
