| Abstract: | Summary The flavonoid content of olive leaves was studied by a method based on thin-layer chromatography and recording UV spectra directly on the layer. Three flavonoid glycosides, quercitrin, rutin and luteolin-7-glycoside, one flavonoid aglycone, luteolin, and chlorogenic acid were found in olive leaves. Three compounds with a biflavonoid-type sructure have been characterized. Ten cultivars were investigated in order to indicate qualitative and quantitative differences. |
