Akeboside Stb, [1] and two new saponins named collinsonin and collinsonidin were isolated from the roots of Collinsonia canadensis. On the basis of chemical and spectral studies, the structure of collinsonin [2] has been established as 3-O-a-L-arabinopyranosylcollinsogenin. 16α-Hydroxyhederagenin, obtained by the hydrolysis of 2, is a new sapogenin named collinsogenin [5]. Collinsonidin [6] has been identified as 3-O-b-D-glucopyranosyl=(1''→3')-a-L-arabinopyranosylhederagenin.
