Article abstract of DOI:10.1007/BF00597707

From the epigeal part of Thermopsis alterniflora Rgl. et Schmalh. (Fabaceae), in addition to formononetin, ononin, cynaroside, and rothindin, two new acylated flavone glycosides have been isolated and, on the basis of chemical transformations and spectral characteristics, their structures have been established as 4',5,7-trihydroxy-3'-methoxyflavone 7-O-(6"-O-crotonoyl-β-D-glucopyranoside) and 4',5,7-trihydroxyflavone 7-O-(6"-O-crotonoyl-β-D-glucopyranoside).
