✦ Synopsis

Six new glycosides, salsasides A -F (1 -6, resp.), were isolated from the stems of Cistanche salsa, together with seven known glycosidic compounds. Their structures were elucidated by means of ester hydrolysis and chemical derivatization, in-depth NMR spectroscopic and mass spectrometric analyses, and by comparison with literature data of related compounds. The new glycosides are based on b-D-glucose (Glc) and a-L-rhamnose (Rha), carrying acetyl (Ac), benzyl (Bn), phenethyl, coumaroyl (Cou), and caffeoyl (Caf) substituents.
