Isolation of chalkones from the seeds of Psoralea corylifolia Linn.

Isolation and characterization of a new chalkone namely 4,2'-dihydroxy-2-(1'''-methyl ethyl)-2-3-dihydro-(4,5,3',4') furano chalkone 1 along with a known chalkone 4,2'-dihydroxy-4'-methoxy-5'-(3', 3'-dimethyl allyl)-chalkone 2 have been carried out from the seeds of the desert variety of Psoralea corylifolia Linn on the basis of spectral data analysis i.e. IR, 1 H NMR, mass and chemical reactions.
