ResumoTwo new phenethyl alcohol glycosides, darendoside A and B (= deacyl martynoside) were isolated from the methanolic extract of the aerial parts of Scutellaria orientalis subsp. pinnatifida, along with four known glycosides, syringin, martynoside, leucosceptoside A and verbascoside. On the basis of chemical and spectral evidence the structures of darendoside A and B were determined as β-(4-hydroxyphenyl) ethyl O-β-d-apiofuranosyl-(1→ 2)-O-β-d-glucopyranoside and β-(3-hydroxy-4-methoxyphenyl)ethyl O-α-l-rhamnopyranosyl- (1→3)-O-β-d-glucopyranoside (=deacyl martynoside), respectively.
