Abstract From the flowers of Cassialaevigata , two new rhamnetin glycosides, the 3-galactosyl(1→4)- galactopyranoside and the related 3-galactosyl(1→6)galactopyranoside, and oleanolic acid 3-galactosyl(1→4)- galactopyranoside have been isolated. These three glycosides have not been isolated earlier from any plant source. The known compounds quercetin, docosyl alcohol, carnaubyl alcohol, ceryl alcohol
