Objective :To investigate the chemical constituents in the roots and rhizome of Trillium tschonoskii. Methods :The roots and rhizome of Trillium tschonoskii were extracted with 70% ethanol and purified by polyamide, silica gel, RP-C18 and Sephadex LH-20 column chromatography. Chemical structures were identified by MS, 1D and 2D NMR experiments. Results:Twelve compounds were i- solated and identified from the ethyl acetate and n-butanol as 7,11-dimethyl-3-methylene-10,11-dihdroxyl-1,6-dodecadien-diol( 1 ) ,2, 6,10-trimethyl-2,10-dihdroxyl-6-dodecene-diol ( 2 ), 3,7,11 -trimethyl-3,9,11 -trihydroxyl-1,6-dodecadiene-glycerol ( 3 ), p-hydroxym- ethyl-benzyl alcohol ( 4 ), 20flF, 22aF, 25 aF-spirostan-5,13-ene-3fl, 21 α-diol ( 5 ), 2-methyl-3,4-dihydroxy-hexanedioic acid ( 6 ), α-L- rhamnopyranosyl ( 7 ), epitrillenogenin-24-O-acetate-l-O-[ 2,3,4,-tri-O-acetyl-α-L-rhamnopyranosyl-( 1 → 2 ) -α-L-arabinopyranoside ] ( 8 ), epitrillenogenin-24-O-acetate-l-O-[ 2,4,-di-O-acetyl-α-L-rhamnopyranosyl-(1-2) -α-L-arabinopyranoside ] ( 9 ), epitrillenogenin- 1-0-[ 2,3,4, -tri-O-acetyl-ct-L-rhamnopyranosyl- ( 1 →2 ) -α-L-arabinopyranoside ] ( 10 ), epitrillenogenin-l-O-[ 2,4,-di-O-acetyl-a-L- rhamnopyranosyl- (1→2) -ct-L-arabinopyranoside ] ( 11 ) and epitrillenogenin-1-0- [ 4-O-acetyl-α-L-rhamnopyranosyl- ( 1→2 ) -ct-L-arabi- nopyranoside ] (12). Conclusion: Compounds 4 - 6 are isolated from this genus for the first time, compounds 1 - 3,11,12 are isolated from this plant for the first time.
