A new sulfated alpha-ionone glycoside from Sonchus erzincanicus Matthews.

ABSTRACT: Sonchus erzincanicus (Asteraceae) is an endemic species in Turkey, where six Sonchus species grow. In this study, a phytochemical study was performed on the aerial parts of the plant. The study describes the isolation and structure elucidation of five flavonoids and two a-ionone glycosides from S. erzincanicus. The compounds were isolated using several and repeated chromatographic techniques from ethyl acetate and aqueous phases that were partitioned from a methanol extract obtained from the plant. 5,7,3',4'-Tetrahydroxy-3-methoxyflavone (1) and quercetin 3-O-beta-D-glucoside (2) were isolated from the ethyl acetate phase, while corchoionoside C 6'-O-sulfate (3), corchoionoside C (4), luteolin 7-O-glucuronide (5) and luteolin 7-O-beta-D-glucoside (6), apigenin 7-O-glucuronide (7) were isol
