New Acylated C,O-Glycosylflavones from Cucumis sativus

Seven new acylated C,O-glycosylflavones were isolated from leaves of Cucumis sativus L. (Cucurbitaceae) variety Gele Tros. The new compounds were isovitexin 4′-O-glucoside-2′′-O-(6′′′′-O-caffeyl)-glucoside (cucumoside A), isovitexin 4′-O-glucoside-2′′-O-(2′′′′-O-caffeyl)-glucoside (cucumoside B), isovitexin 4′-O-(2′′′-O-caffeyl)-glucoside-2′′-O-glucoside (cucumoside C), isovitexin 4′-O-glucoside-2′′-O-(6′′′′-O-sinapoyl)-glucoside (cucumoside D), isovitexin 4′-O-glucoside-2′′-O-(2′′′′-O-sinapoyl)-glucoside (cucumoside E), isovitexin 4′-O-glucoside-2′′-O-(2′′′′-O-feruloyl)-glucoside (cucumoside F), and isovitexin 4′-O-glucoside-2′′-O-(2′′′′-O-p-coumaroyl)-glucoside (cucumoside G).
