CHEMICAL INVESTIGATIONS ON THE ROOTS OF YELLOW FLOWERING ASPHODELINE SPECIES IN TURWY

Abstract

Four Asphodeline species with yellow flowers growing in Turkey (A. baytopae E.Tuzlac~, A. brevicaulis (Bertol.) J.Gay ex Baker subsp. brevicauli~ var. brevicaulis, A. liburnica (Scop.) Reichb. and A. lutea (L.) Reichb.) have chemically been investigated . The existence of two flavonoids (apigenin and luteolin), six anthracene derivatives (aloe-emodin, asphodelin, chrysophanol, isochrysophanol, physcion and rhein) and a phenolic acid (chlorogenic acid) have been shown in the roots of the species. The amount of anthracene derivatives in these four species has also been compared. A.baytopae was found the richest species in anthracene derivatives whereas A. brevicaulis subsp. brevicaulis var. brevicaulis was the poorest .

Four Asphodeline species with yellow flowers growing in Turkey (A. baytopae E.Tuzlacı, A. brevicaulis (Bertol.) J.Gay ex Baker subsp. brevicaulis var. brevicaulis, A. liburnica (Scop.) Reichb. and A. lutea (L.) Reichb.) have chemically been investigated .The existence of two flavonoids (apigenin and luteolin), six anthracene derivatives (aloe-emodin, asphodelin, chrysophanol, isochrysophanol, physcion and rhein) and a phenolic acid (chlorogenic acid) have been shown in the roots of the species. The amount of anthracene derivatives in these four species has also been compared. A.baytopae was found the richest species in anthracene derivatives whereas A. brevicaulis subsp. brevicaulis var. brevicaulis was the poorest .Key words: Asphodeline, anthraquinones, flavonoids, phenolic acid.
