From the aerial parts of Rhinanthus angustifolius subsp. grandiflorus,
a new iridoid glucoside, 6'-O-benzoylshanzhiside methyl ester, was is
olated together with the known compounds, aucubin. melampyroside, muss
aenoside, shanzhiside methyl ester, 8-epiloganin, gardoside methyl est
er and 2-(4-hydroxyphenyl)ethylalcohol. The structure of the new compo
