Objective: To study the phenylpropanoid constituents of Smilax trinervula.
Methods: The chemical constituents were isolated and purified by macroporous adsorption resin chromatography, gel chromatography and high performance liquid chromatography. Their structures were identified by spectroscopic analysis and comparison with literatures.
Results: Nine phenylpropanoid compounds were isolated and their structures were identified as( +)-lyoniresin-4-yl β-D-glucopyranoside( 1),(-)-8’-epilyoniresin-4-yl β-glucopyranoside( 2),( +)-lyoniresin-4’-yl β-glucopyranoside( 3),(-)-lyoniresinol-2α-O-β-D-glucopyranoside( 4),( +)-lyoniresinol( 5),icariol A2( 6),icariol A2-4-O-β-D-glucopyranoside( 7),7S,7’S,8R,8’R-icariol A2-9-O-β-D-glucopyranoside( 8) and( +)-syringaresinol-4’-O-β-D-glucopyranoside( 9).
Conclusion: All the compounds are isolated from Smilax genus for the first time.
