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.
