Abstract A new lignan rhamnoside identified as 2, 6-di (4', 5'-dihydroxyphenyl)-3, 7-dioxabicyclo[3.3.0]octane-1-hydroxy-5-O-rhamno-pyranoside (1) has been isolated from the ethanolic extract of seed pods of Bauhinia retusa. Its structure was established by extensive spectroscopic techniques (UV, IR, ID NMR, 2D NMR, HRESIMS).
