Comparative Chemical Investigation of Brachychiton australis (Schott & Endl.) A. Terracc. and Brachychiton discolor F.Muell

Brachychiton australis (Schott and Endl.) A. Terrac discolor F.Muell. (Malvaceae) are widely grown in Egypt observed as important biological species. Chemical studies of the 70% methanol/water extracts leafy branches both species were carried out based on isolation characterization phytochemical constituents. Chromatographic spectroscopic methods revealed identification twelve phenolics. Eight isolated flavonoids (vicenin, schaftoside, violanthin, isoviolanthin, luteolin 7-O-β-glucuronide, apigenin 7-O-β-glucopyranoside, acacetin) characterized for B. while three phenolic acid derivatives (trans-p-coumaric acid, trans-p-coumaric acid-O-glucoside, chlorogenic acid) one flavonol glycoside (rutin) considered discolor. Except rutin, all compounds reported first time each The LC-ESI-MS assay annotation additional nineteen including eight flavonoids, five acids, two organic fatty saccharide, amino acid. most could be useful further pharmaceutical applications. Moreover, this study presents a step forward approaching chemosystematic revision examined within genus
