摘要
A new acylated neohesperoside derivative, 1-octyl-4'-isovaleroyl-neohesperoside (1), was isolated from Geranium purpureum Vill. (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 (H-1, C-13, COSY, HSQC and HMBC) spectroscopy and ESI-TOF-MS.
