Two new flavone glycosides from Pongamia pinnata were characterized on the basis of chemical and spectral evidence as 3,5,3′,4′-tetrahydroxy-7-methoxy-flavone-3-O-[{α-L-arab inopyranosyl (1-3)} { β-D-galactopysanosyl (1-6)}-β-D-galactopyranoside] and 3,5,3′,4′-tetrahydroxy-7-methoxy-flavone-3-O-[{α-L-arab inopyranosyl (1-3) } { βD-galactopysanosyl (1-6) [-β-D-galactopyranoside].

Focuses on the characterization of a flavonoid diglycoside from the bark of Punica granatum (Punicaceae), a shrub cultivated throughout India. Lists of compound discovered; Way in extracting the flavonoid and compounds from the shrub; Activities exhibited by the extracts of the shrub.

From the seeds of Dendrocalamus strictus, two new triterpenoids, 1β,2α,3β,24-tetrahydroxy-16β- O -acetylolean-12-ene-24- O -β-d-glucopyranoside and 16β- O -acetylolean-12-ene-28-oic acid 28- O -α-{l-rhamnopyranosyl(1→3)}-b-d-arabinopyranoside have been isolated and their structuresestablished on the basis of spectral and chemical studies.
