PHYTOCHEMICAL SCREENING AND EVALUATION OF ANTIFUNGAL ACTIVITY OF GALL EXTRACTS OF QUERCUS INFECTORIAAbstract
The objective of the present work is to study the antifungal activity of gall extracts of Quercus infectoria (Q. infectoria) (Family: Fagaceae). The plant commonly known as gall oak, is a small shrub found in Greece, Asia Minor and Iran. The gall of Quercus infectoria macroscopically, is globose with horny appearances on external surface (1-1.5 cm in diameter) giving rough touch, greyish-brown to brownish-black in colour externally with unpleasant odour. The galls of Quercus infectoria have been pharmacologically documented to possess astringent, antidiabetic, antitremorine, local anaesthetic, antiviral, antibacterial, antifungal and anti-inflammatory activities. The powder of Quercus infectoria gall was subjected to extraction with Chloroform, Ethanol, Acetone, Ethyl acetate and Water using soxhlet extractor. The extracts after preliminary phytochemical investigation had shown the presence of Carbohydrates and Tannins. The antifungal activity was performed by agar cup plate method against two fungi, Penicillium sps and Aspergillus sps. The zone of inhibitions were compared with standard antifungal drug clotrimazole. The chloroform extract exhibited good anti-fungal activity as compared to other extracts.
