Article abstract of DOI:10.1002/hlca.19820650539

Two new iridoid glycosides, nigroside 1 (= 6-O-(3-O-cinnamoyl-α-L-rhamnopyranosyl)aucubin (2) and, nigroside 2 (= 6-O-(2-O-cinnamoyl-α-L-rhamnopyranosyl)aucubin (3), and the known compound laterioside (1) have been isolated from extracts of the stems of Verbascum nigrum L., and their structures established primarily on the basis of NMR spectroscpoy.Harpagoside (4), a known iridoid glucoside was also isolated from the roots of this plant.
