A new phenylethanoid glycoside, sculponiside (1) was isolated from the aerial parts of Isodon sculponeatus (Vaniot) Kudo, along with six known compounds martynoside (2), verbascoside (3), (+)-hydroxypinoresinol-8-O-β-D-glucoside (4), cedrusin (5), 7-megastigmene-3S,5R,6R,7E,9S-tetrol (6) and 4-oxo-β-ionol-β-D-glucopyranoside (7). Their chemical structures were elucidated from physicochemical data and by acidic hydrolysis.
