Isolation and Structure Elucidation of Phenolic Compounds of Carob Leaves Grown in Egypt
نویسنده
چکیده
Carob leaves (Ceratonia siliqua L.), grown in Egypt have not fully identified in Egypt. Therefore, eight major phenolic compounds were isolated from the aqueous ethanolic extract using different methods of chromatography; gallic acid, quercetin 3-O-4C1-B-D-glucoside (Isoquercetin), Kaempferol 3-O1C4-"-Lrhamnoside (Afzelin), Quercetin 3-O-1C4-"-L-rhamnoside (Quercitrin), 1,2,6 tri-O-galloyl-B-D4C1glucopyranose, (-)-Epigallocatechin-3-O-gallate, kaempferol and quercetin. Their structures established by conventional methods of analysis. This is the first phytochemical study of polyphenolic content of carob leaves grown in Egypt.
