Two undescribed stilbenoid diglycosides, dendrosonside A and dendrosonside B ( 1 and 2 ), were isolated from the stems of Dendrobium 'Sonia'. Their structures were elucidated based on 1 D/2D NMR and HRESIMS. The glycosyls contained in the two isolates were determined as D-glucose by acid hydrolysis and GC-MS analyses. In addition, 1 and 2 were further tested for the inhibition of nitric oxide production.
