Aurones occurs rarely in nature and only a limited number of aurones has been isolated from plant source. Aurones are important contributor to pigmentation of the flowers by virtue of their bright golden yellow colour. A series of naturally occurring aurones have been reported to exhibit antiplasmodial activity and has been used as a potential antileishmanial drug. . From the ethanolic extract of the heartwood of Pterocarpus santalinus (Fam.:Papilionaceae), commonly known as Red Sandalwood, two new aurone glycosides 6 hydroxy 5 methyl 3', 4', 5' trimethoxy aurone –4-O--a-L –rhamnopyranoside and 6,4' dihydroxy aurone 4-O-rutinoside have been isolated and their structures were elucidated on the basis of chemical and spectral studies.
