Comparative qualitative and quantitative determination of flavonoids and phenolic contents of Cinnamomum verum J. Presl and Cinnamomum camphora L. Growing in Egypt

The present study aims to compare qualitatively and quantitatively the flavonoids and phenolic contents of the leaves of Cinnamomum verum J.Presl and Cinnamomum camphora L. Growing in Egypt by established methods. Total phenolics and total flavonoids contents were determined by using UV-visible spectroscopy method. The qualitative and quantitative estimation of the flavonoid and phenolic acid contents in the leaves of Cinnamomum verum J.Presl and Cinnamomum camphora L. were performed by High performance liquid chromatography (HPLC). The content of total phenolics of different Cinnamomum leaf extracts was (20.61 and 19.65 mg/100 g), respectively. While, the content of total flavonoids of the leaves of Cinnamomum verum J.Presl and Cinnamomum camphora L. were (2.01 and 3.88 mg/100 g). The HPLC analysis of the flavonoid contents revealed the presence of eleven compounds in the leaf of Cinnamomum camphora L. with rutin as a major compound (5309.6 ppm) followed by quercetrin (6025.5 ppm) and nine compounds were estimated in the leaf of Cinnamomum verum J.Presl with rosmarinic as a major compound (6194 ppm) then Naringin (2281.3 ppm).
