| Abstract: | Eight flavonoids are present in the leaves of Asclepias syriaca. Three have been identified as quercetin, kaempferol, isorhamnetin; a structure of a fourth, 3,5,3′,4′-tetrahydroxy-7,8-(2″,2″-dimethyl-4″-methyl-5″,6″) pyranoflavone(I), has been established by study of its spectral properties (UV, IR, MS, NMR) and those of its acetate. |
