A new acylated neohesperoside derivative, 1-octyl-4′-isovaleroyl-neohesperoside (1), was isolated from Geranium purpureum Vili. (Geraniaceae) together with the known compounds quercetin-3-rutinoside and gallic acid. The identification of the isolated compounds was carried out by spectroscopic analysis including 1D- and 2D- NMR (1H, 13C, COSY, HSQC and HMBC) spectroscopy and ESI-TOF-MS.
