Abstract
Four hitherto unknown aristolane-type sesquiterpenes, including one novel 8,9-secoaristolane, namely secoaristolenedioic acid (1), two aristolone derivatives, namely 1α,2β-dihydroxyaristolone (2), 9-epidebilon (3), and one rare aristolane-chalcone hybrid, namely 3′-hydroxynardoaristolone A (4) were isolated from the ethanol extract of the roots and rhizomes of Nardos-tachys chinensis. Their structures were elucidated on the basis of extensive spectroscopic analysis. In addition, the structure of aristolanhydride, recently isolated from the same species, was corrected by reanalysis of the published NMR data.
