title: Dihydrophenanthrenes from Spiranthes sinensis.
abstract: Six novel dihydrophenanthrene derivatives, sinensols A-F (1-6), were isolated from the aerial parts of Spiranthesis sinensis. Their structures were determined on the basis of various spectroscopic data, in particular those yielded by MS and 2D NMR techniques.
