Abstract (english)

The leaves and fruits of strawberry tree – Arbutus unedo L., collected from two separate geographic locations in Croatia were investigated to determine their flavonoid composition and content. Quercitrin, isoquercitrin, hyperoside and rutin were identified in all leaf samples by means of thin-layer chromatography; the fruits contained only isoquercitrin. Chlorogenic acid was present in some leaf samples. The content of flavonoids depended on the plant organ investigated, date of collection and the locality. Spectrophotometric determination of the flavonoids indicated that the leaves are richer in flavonoids (0.52-2.00%) than in fruits (0.10-0.29%).

Abstract (croatian)

Sastav i količina flavonoida određeni su u listovima i plodovima planike – Arbutus unedo L., sabranima na dva nalazišta u Hrvatskoj. Tankoslojnom kromatografijom utvrđena je prisutnost kvercitrina, izokvercitrina, hiperozida i rutina u svim uzorcima listova, dok su plodovi sadržavali samo izokvercitrin. Klorogenska kiselina je dokazana samo u nekim listovima. Količina flavonoida bila je uvjetovana biljnim organom, datumom, te zemljopisnim položajem mjesta sabiranja. Spektrofotometrijska je analiza pokazala da listovi sadrže veću količinu flavonoida (0.52-2.00%) u usporedbi s plodovima (0,10-0,29%).
