摘要

Narjatamanins A ( 1 ) and B ( 2 ), a pair of epimers possessing a novel 2,3- seco -iridoid skeleton with an unusual 1,10-oxygen bridge, were isolated from the whole plants of Nardostachys jatamansi . Their structures were elucidated by a combination of various spectroscopic methods, including HRESIMS, IR and 1D and 2D NMR techniques. The absolute configurations of 1 and 2 were established by electronic circular dichroism (ECD) calculations. The pharmacological activities of 1 and 2 to alleviate AD-like symptoms were also evaluated using the Caenorhabditis elegans Alzheimer's disease (AD) pathological model, and narjatamanins A ( 1 ) and B ( 2 ) showed statistically significant delay in the worm paralysis phenotype of AD-like symptoms.
