Study of the inhibitory effect of Quercus Coccifera's aqueous extract on Staphylococcus aureus and Pseudomonas aeruginosa In vitro

Abstract

The use of therapeutic herbs has become of great importance these days due to the increase in drug resistance. From a long time ago the Venus' navel plant has been used to treat infections. In this study the antibacterial effect of the aqueous extract from the Quercus coccifera (jaft) herb, under laboratory conditions. This study was carried out experimentally. After collecting the Venus navel herb, it was dried in a warm dry environment away from direct sunlight in the shade. The alcoholic extract was prepared using a standard method. Clinical samples of staphylococcus aureus and pseudomonas aeruginosa were acquired from Ilam's health care institutes. The inhibitory effect of the extracts was analysed in the Mueller Hinton using the disk diffusion method for both bacteria. Then MIC and MBC of the extracts was determined using the Macro broth dilution method. At its highest concentration the aqueous extract had an inhibition zone of 27.2 and 23.7 mm on staphylococcus aureus and pseudomonas aeruginosa consecutively. The MIC and MBC for staphylococcus aureus were 10 and 12.5 µg/ml and for pseudomonas aeruginosa they were 10 and 17.5 µg/m consecutively. The results of this study show the strong antimicrobial effect of jaft's aqueous extract on staphylococcus aureus and pseudomonas aeruginosa and if more studies are based on this topic it could be a substitute for common antibiotics.

Use of Nepeta clarkei extracts for controlling honey bee pathogenic bacteria and mosquito larvae

“…After 18-24 h the diameter of the inhibitory zones was measured using a ruler and noted. The tests were repeated three times (Judaki et al 2014). The crude aqueous extract of N. clarkei was prepared following the protocol of Khan et al (2012).…”

“…The tests were repeated three times. [22] Amikacin 30 mg (CT0107B) discs were used for positive control, as a standard antibiotic.…”

Demonstration of Effect of Oak Root Extract on Burn Wounds in Rats

“…In recent years, several natural and traditional products such as aloe vera, olive oil, centaury oil and honey without any side effects have been increasingly used in the management of burns. Thus, investigators are seeking natural products with proven biological effects in the management of burn (3)(4)(5)(6)(7)(8). It is thought that extract derived from oak root is one of these products, which is commonly used in Maraş province (5).…”

“…It is thought that extract derived from oak root is one of these products, which is commonly used in Maraş province (5). Based on the information gathered from local people, roots of oak are boiled following mincing, which then applied over burn wound for treatment (5). Oak root extract is a traditional cure used by local people of Maraş province.…”
