[Phenylpropanoid Constituents of Smilax trinervula]
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.

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
