A New Sesquiterpene from the Roots of Lindera strychnifolia

A new sesquiterpene lactone, strychnilactone (1), together with five known sesquite- rpenoids, linderane (2), lindenenol (3), linderalactone (4), hydroxylindestenolide (5), pseudoneo- linderane (6) have been isolated from the extracts of Supercritical Fluid Extraction of Lindera strychnifolia. The structure of the new compound was elucidated by means of spectroscopic analysis. And the relative configuration of 1 was assigned on the basis of NOE analysis.
