Phenolic Compounds from Lactuca viminea L.

Abstract The aerial part of Lactuca viminea L. was examined for the presence of phenolic compounds. Six different flavonoids were isolated and identified by UV spectra, TLC, HPLCDAD , 1H NMR and 13C NMR. They were identified as apigenin, luteolin, quercetin, luteolin-7-O-glucoside, quercetin-3-O-glucoside and luteolin-7-O-glucuronide-6″methyl ester. Three phenolic acids were also detected: caffeic, ferulic and chlorogenic acid.
