Abstract:
The first new isorhapontigenin dimer glucoside gnetupendin D (1) and a stilbene dimer coupled by a resveratrol and an oxyresveratrol with a cis-dihydrobenzofuran were obtained from the lianas of Gnetum pendulum C. Y. Cheng (Gnetaceae), along with nine known compounds. Their structures and stereochemistry were elucidated by chemical and spectral evidence, especially 2D NMR spectroscopic techniques. Pharmacological activities on anti-inflammation have been tested.
