  Methanolic extracts of leaves of thompson seedless grape, flame seedless grape, zizyphus, pomegranate and fig were screened for their phytochemical constituents and also investigated for their antifungal activity in vitro against phytopathogenic fungi, Alternaria solani, Botrytis cinerea, Botrytis fabae, Fusarium oxysporum and Fusarium solani. Phytochemical screening of crude methanolic extracts revealed the presence of terpenes, tannins, flavonoids, alkaloids, carbohydrate or glycosides, phenolic glycosides and resins in all extracts, while saponins were not detected from any extracts except zizyphus and fig. Zizyphus leaves had the highest concentration of total polyphenols and total flavonoids content which were 147.47 mgGAE/g and 16.35 mgQE/g, respectively. HPLC analysis identified twelve polyphenolic compounds; pyrogallic acid, gallic acid, protocatechuic, catechin, p-hydroxy ben.. View More»
