Antibacterial activities of extracts from twelve Centaurea species from Turkey

Abstract

Members of the genus Centaurea (Asteraceae) have been used in traditional plant-based medicine. The methanol extracts of twelve Centaurea species, of which five are endemic to Turkey flora, were screened for antibacterial activity against four bacteria (Escherichia coli, Bacillus cereus, Salmonella enteritidis, Staphylococcus aureus). The antibacterial activity was evaluated by the microdilution method and the minimum inhibition concentrations (MIC) of the extracts were determined. C. cariensis subsp. microlepis exhibited an antimicrobial effect on all tested microorganisms. The extracts from eight Centaurea species (C. balsamita, C. calolepis, C. cariensis subsp. maculiceps, C. cariensis subsp. microlepis, C. kotschyi var. kotschyi, C. solstitialis subsp. solstitialis, C. urvillei subsp. urvillei and C. virgata) possessed antibacterial activity against several of the tested microorganisms

Phytochemical profile and some biological activities of three Centaurea species from Turkey

“…Several studies are present in literature reporting the use of liquid chromatography electrospray ionization tandem mass spectrometry to perform quantitative analyses [18,19]. In this study, an accurate method on a mass spectrometer equipped with a The antibacterial effect of C. balsamita seen in this study has been reported previously in eight Centaurea species [4,9]. Sımilarly, the antifungal activity of C. balsamita has been reported in Candida krusei [10].…”

“…In Turkish traditional medicine, these species are widely used as expectorant, antidiabetic, antipyretic and antidiarrhoeal [2]. Centaurea species are known to have various biological activities such as antimicrobial [4], antifungal [5], antiinflammatory [6], antiulcerogenic [7], antioxidant [8], antiplasmoidal [9], antiprotozoal [4], cytotoxic [9,10] and anticancer [10].…”

Preparation of Strong Antidandruff Shampoo Using Medicinal Plant Extracts: A Clinical Trial and Chronic Dandruff Treatment

“…Flowers of P. granatum, M. chamomilla and S. officinalis, leaves of M. piperita and R. officinalis and U. dioica roots were fully separated and milled. In this stud, Soxhlet apparatus was used for extraction and according to Tekli et al method also Rotary evaporation apparatus was used to evaporate methanol (48). Then 15 g of each powder was dissolved in 300 mL methanol 96% (Merck, Germany) and shaked for 24 hours by shaker (KS 130 Control Mixing Orbital Shaker, IKA Company, Germany) after necessary time shaking, these solvents were filtered by Whatman NO.…”
