Two compounds were isolated from roots of Astragalus membranaceus Bunge. On the basis of chemical spectro scopic evidence, they were identified as Formononetin (compound E) and Linoleic acid (9Z,12Z-Octadecadienoic acid) (compound F). Linoleic acid (9Z,12Z-Octadecadienoic acid) was reported the first time from the genus Astragalus.
