Özet
A novel glycoside, hirsutusoide (1), characterized as 2-( o-hydroxyphenyl)-2-hydroxyethenyl- O-β-glucopyranoside, was isolated from the endemic Acanthus hirsutus Boiss. In addition to compound 1, three known glycosides, luteolin-7- O-β-D-glucuronide (2), β–sitosterol-3- O-β-D-glucopyranoside (3) and (2 R)-2- O-β-D-glucopyranosyl-2 H-1,4-benzoxazin-3(4 H)-one (4), were also isolated. Compound 2 was the first report from this genus. Antimicrobial and antioxidant activity of the extracts and the novel compound were investigated by determining MIC (μg/mL) and IC 50 (μg/mL) values, respectively.
