Key Word Index - Trillium tschonoskii; Liliaceae; 18-norspirostanol oligoside; acetylated glycoside. Three 18-norspirostanol oligoglycosides partly acetylated in their sugar moieties were isolated from the underground parts of Trillium tschonoskii.Their structures were characterized, as 1-O-<2'',3'',4''-tri-O-acetyl-α-L-rhamnopyranosyl-(1--->2)-α-L-arabinopyranosyl>-epitrillenogenin-24-O-acetate, 1-O-<2'',3'',4''-tri-O-acetyl-α-L-rhamnopyranosyl-(1--->2)-α-L-arabinopyranosyl>-epitrillenogenin and 1-O-<2'',4''-di-O-acetyl-α-L-rhamnopyranosyl-(1-->2)-α-L-arabinopyranosyl>-epitrillenogenin-24-O-acetate.
