Abstract

The methanol extract of the Balkan endemic species Jurinea tzar-ferdinandii Davidov demonstrated weak antioxidant activity against DPPH center dot and ABTS+center dot and low inhibitory potential against acetylcholinesterase (8.3% Inh.) and tyrosinase (IC50 = 208 +/- 8 mu g/mL) enzymes. Phytochemical investigation of the extract led to isolation and identification of apigenin, luteolin, apigenin-7-O-glucoside, apigenin-4'-O-glucoside, apigenin-7-O-gentiobioside, luteolin-4'-O-glucoside, rutin, narcissin, chlorogenic and 1,5-dicaffeoylquinic acid. With exception of apigenin and rutin, all isolated compounds are reported for the first time in the representatives of genus Jurinea. The distribution of flavonoids was discussed from chemotaxonomic point of view.
