Phochinenins A – F, Dimeric 9,10‐Dihydrophenanthrene Derivatives, from Pholidota chinensis

Six new compounds, phochinenins A–F ( 1 – 6 ), dimerized from 9,10‐dihydrophenanthrene and dihydrostilbene through direct coupling or an oxygen bridge, along with eight known compounds, were isolated from the whole plants of Pholidota chinensis. Their structures were elucidated on the basis of extensive spectroscopic investigations (1D‐, 2D‐NMR, and HR‐EI‐MS).
