Abstract

Two new bibenzyls ( and ) were isolated from the pseudobulbs of (Rolfe) Rolfe along with six known compounds, including isoarundinin I (), isoarundinin II (), bulbocodin D (), batatasin III (), 5,3'-dihydroxy- 4-(-hydroxybenzyl)-3-methoxybibenzyl () and shancigusin F (). Their structures were established on the basis of spectroscopic methods. These compounds showed potent DPPH free radical scavenging effects with IC values ranging from 49.72 ± 0.35 μM to 65.41 ± 0.49 μM.
