Isolation and structure of wightional and wightiolide from Andrographis wightiana

Two new ent-labdane-type diterpenoids, wightional and wightiolide have been isolated from the leaves of Andrographis wightiana. Their structures were determined on the basis of extensive 1H and 13C, 1H homonuclear COSY, and HMBC NMR spectroscopic studies. To correlate the newly isolated diterpenes with wightionolide, a number of derivatives of wightionolide have been prepared and characterized.
