Steroidal saponins from the rhizomes of Trillium tschonoskii Maxim.

Ten compounds (1-10) were isolated from the underground parts of Trillium tschonoskii Maxim.. Their structures were elucidated on the basis of spectroscopic evidence using 1D and 2D-NMR and chemical methods, and identified as two sterols (1-2), six spirostanols (3-8) and two furostanols (9-10). The results indicate a close relationship between the two genera Trillium and Paris, and the chemotaxonomic significance of these compounds was summarized.
