A chemical study of Ostrya carpinifolia scop widespread in Syria
Abstract
phytochemical screening was achieved on its’ parts (leaves, fruiting cones) to evaluate the presence of some secondary metabolites, total phenol and flavonoid content assays. Phenol content was quantified according to Folin-Ciocaltu method using Gallic acid (Ga) as standard, and flavonoids content was quantified according to Aluminium trichloride method using Rutin (R) as standard. Phytochemical tests revealed the presence of tannins, flavonoids, and cardiac glycosides, while alkaloids and saponins were absent in the studied parts of the plant. Methanol extracts of leaves contained the highest level of total phenols and flavonoids (35.29 mg Ga E/g DW and 1.13 mg R E/g DW, respectively), while the contents of phenoles and flavonoids in fruiting cones were (5.67 mg Ga E/g DW, 0.3 mg R E/g DW, respectively).
