The flowers of Hemisteptia lyrata B. afforded two known acylglycerylgalactosides, 2',3'-di-O-(9Z,12Z,15Z-octadecatrienoyl)glyceryl ${\beta}$-D-galactopyranoside (1) and 2'-O-(9Z,12Z,15Z-octadecatrienoyl)glyceryl ${\beta}$-D-galactopyranoside (2), and a new sesquiterpene galactopyranoside, 7-eudesmene-1${\beta}$,4${\beta}$-diol-1-O-${\beta}$-D-galactopyranoside (3). This is the first time that galactopyranosides (1-3) have been isolated from the genus Hemisteptia. Their structures and stereochemistry were elucidated by 1D and 2D NMR data, including COSY, NOESY and HMBC experiments.
