Thesis on antibacterial properties of medicinal plants

Abstract This study was carried out with an objective to investigate the antibacterial and antifungal potentials of leaves of Cassia fistula Linn. Voucher specimens from plant materials were deposited at the Herbal Museum, Department of Pharmacology, Faculty of science, King Abdulazziz University of Medical Sciences, for identification.

antimicrobial activity of plant extracts protocol

It attribute of the presence of higher amount of phenolic compounds in these extracts Plant leaves were used in medicine as an anti-inflammatory, antiseptic and antifungal agent for diseases of skin Therapeutic efficacy of many indigenous plants for several disorders has been described by practitioners of traditional medicine.

Control experiments were carried out under similar condition by using ampicillin, chloramphenicol, ciprofloxacin, and norfloxacin for antibacterial activity and nystatin and griseofulvin for antifungal activity as standard drugs.

Phyto chemical analysis of the crude extracts of the ethanol and water of the leaves of the Ziziphus spina-christi declared the presence of alkaloids, tannins, saponins, glycosides, flavonoids, steroids and terpenoids The plant specimens were identified in department of Pharmacognosy I.

Also, roots extract of Saussurea lappa tested showed excellent antibacterial activity against B.

It attribute of the presence of higher amount of phenolic compounds in these extracts More yields of extracts were collected by this method of extractions. Abstract This study was carried out with an objective to investigate the antibacterial and antifungal potentials of leaves of Cassia fistula Linn. Control experiments were carried out under similar condition by using ampicillin, chloramphenicol, ciprofloxacin, and norfloxacin for antibacterial activity and nystatin and griseofulvin for antifungal activity as standard drugs. In many developing countries, traditional medicine is one of the primary healthcare systems. The reaction mixture contained 1 mL of plant extract, 0. Zone of inhibition of extracts were compared with that of different standards like ampicillin, ciprofloxacin, norfloxacin, and chloramphenicol for antibacterial activity and nystatin and griseofulvin for antifungal activity.

These findings were in agreement with that previously recorded where phenolic compounds enhanced probiotic bacteria, that explain the safety of using plant extract in the growth of some probiotic bacteria that have a big role in microbial balance especially in children Antioxidant activity was recorded based on absorbance on the final day.

Drugs derived from natural sources play a significant role in the prevention and treatment of human diseases.

Antimicrobial activity of plant extracts thesis

However, over the past few decades, these health benefits are under threat as many commonly used antibiotics have become less and less effective against certain illnesses not, only because many of them produce toxic reactions, but also due to emergence of drug-resistant bacteria. In the current investigation carried out, a screening of hydroalcoholic extracts of Cassia fistula leaves against pathogenic bacteria and fungi is done in order to detect new sources of antimicrobial agents. More yields of extracts were collected by this method of extractions. The absorbance at nm was measured with spectrophotometer Hitachi U, model and used to calculate the phenolic contents using gallic acid as a standard. This article has been cited by other articles in PMC. The phytochemical analyses of the plants were carried out. In both methods, antioxidant activity is described by percent inhibition. The hydroalcoholic extract yields a dark greenish solid residue weighing 5. The antimicrobial activity was determined in the extracts using agar disc diffusion method. The resulting mixture was then diluted to Preliminary Phytochemical Screening The extracts were subjected to preliminary phytochemical testing to detect for the presence of different chemical groups of compounds.

Approximately 1 mL of each extract was added to a solution containing linoleic acid 0.
