Abstract 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 β‐D‐glucose (Glc) and α‐L‐rhamnose (Rha), carrying acetyl (Ac), benzyl (Bn), phenethyl, coumaroyl (Cou), and caffeoyl (Caf) substituents.
