The stimulating effect of subinhibitory concentrations of antibiotics on the production of verocytotoxin (VT) by enterohaemorrhagic Escherichia coli (EHEC) O157:H7 has been claimed. The purpose of this study was to find an alternative, but bioactive medicine for the treatment of this organism. Fifty-eight preparations of aqueous and ethanolic extracts of 38 medicinal plant species commonly used...

BACKGROUND Galls of Quercus infectoria have been traditionally used to treat common ailments, including yeast infections caused by Candida species. OBJECTIVE This study aimed to evaluate the in vitro anti-Candida activity of Q. infectoria gall extracts against selected Candida species. MATERIALS AND METHODS Methanol and aqueous extracts of Q. infectoria galls were tested for anti-Candida ac...

The present study indicates the efficacy of extracts and fractions of Quercus lusitania var. infectoria galls (Oliv.) as larvicidal agents and their possible use in biological control of Culex pipiens, the urban nuisance mosquito. Extracts and fractions were tested against second and fourth instar larvae. The LC(50) values of gallotannins were 335 and 373 ppm, respectively for the 2nd and 4th i...

The present study aimed at evaluating the antibacterial activity of methanol extract of Ruta chalapensis, L., (Rutaceae), Quercus infectoria Oliver., (Fagaceae) and Canthium parviflorum Lam., (Rubiaceae) against Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella oxytocoa, Klebsiella pneumoniae and Proteus mirabilis. The experiment was carried out using disc diffusi...

In the present study, free radical scavenging activities of the two plants, Oroxylum indicum (L) Kurz and Quercus infectoria G. Olivier were investigated. Free radical scavenging activities of stem bark of O. indicum and insect galls of Q. infectoria were characterized by the HPLC method developed by D. Chandrashekhar, et al, 2005 using Waters 100 RP-18e column (250 mm × 4 mm, 5 μM) in which st...

The present study aims to investigate the analgesic activity of the methanol extract of the galls of Quercus infectoria in rats using hot plate and tail-flick methods. The extract was administered intraperitoneally at a dose of 20 mg/kg while morphine sulfate and sodium salicylate (10 mg/kg) served as standards. The methanol extract exhibited significant analgesic activity in the tail-flick mod...

The aim of this study was to develop a preparation of a hydroalcoholic extract of Quercus infectoria in order to study the physicochemical parameters, and to identify and quantitatively determine the amount of Polyphenols and Tannin in the galls and in the extract. Preparation of an extract rich in Tannin from the galls of Quercus infectoria, as an astringent, can make incorporation into recta...
