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-2β-isovaleroxy-9α-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 e...
Three new germacrane-type sesquiterpenoids, volvalerenal F (1), volvalerenal G (2) and volvalerenic acid D (3), along with five known compounds 4-8, were isolated from the CHCl₃ soluble partition of the ethanol extract of Valeriana officinalis var. latiofolia. The structures of the new compounds were determined on the basis of spectroscopic evidence, including their 1D- and 2D-NMR spectra, as w...
The structure of an iridolactone isolated from Valeriana laxiflora was established as (4R,4aR,6S,7S,7aS)-6-hydroxy-7-hydroxymethyl-4-methylperhydrocyclopenta[c]pyran-1-one chloroform solvate, C(10)H(16)O(4).CHCl(3). The two rings are cis-fused. The delta-lactone ring adopts a slightly twisted half-chair conformation with approximate planarity of the lactone group and the cyclopentane ring adopt...
Bornyl caffeate (1) was previously isolated by us from Valeriana (V.) wallichii rhizomes and identified as an anti-leishmanial substance. Here, we screened a small compound library of synthesized derivatives 1-30 for activity against schistosomula of Schistosoma (S.) mansoni. Compound 1 did not show any anti-schistosomal activity. However, strong phenotypic changes, including the formation of v...
