Abstract

This study focused on the profiling of phenolic constituents in 80% methanolic extracts of the leaves of some Jasminum species cultivated in Egypt and their antioxidant activities. Phenolic profiling was performed by total phenolic contents, total flavonoid contents and HPLC-DAD for selected species in comparison to authentic standards. DPPH assay was used to estimate the antioxidant activities of Jasminum azoricum L., Jasminum humile L., Jasminum multiflorum (Burm.f.) Andrew, Jasminum officinale L., Jasminum sambac (Ait) L. "Arabian Nights cultivar" and Jasminum sambac (Ait) L. "Grand Duke of Tuscany cultivar". Jasminum multiflorum showed the highest antioxidant activity among selected species with IC50 of 34.8 µg/ml. J. multiflorum showed high concentrations of hydroxytyrosol, protocatechuic acid, hydroxybenzoic acid, kaempferol-3-O- neohesperidoside, and quercetin-3-O-glucoside with concentrations of 977.1 µg/g, 2224.7 µg/g, 714.8 µg/g, 1738.8 µg/g, and 4356.1 µg/g, respectively.
