The aim of the study was to determine antibacterial effectiveness four different crude drug extract Terminalia chebula (Badi Harad) extracted in methanol, ethanol acetone and aqueous solvent against certain food borne microorganisms i.e. Staphylococcus aureus, Salmonella typhi, Escherichia coli, Vibrio cholerae, Bacillus cereus, subtilis. Methanolic had strongest effect, followed by acetone, et...
Parasitic nematodes, especially Haemonchus contortus (Rudolphi), are among the most common and economically important causes of disease in sheep and goats owned by pastoralists and small holder farmers in Africa. The control of these infections relies mainly on the use of anthelmintic drugs. However, herbal preparations are widely used by pastoralists and small holder farmers for the treatment ...
methanolic extract of 15 iranian medicinal plants were prepared and tested for their cytotoxic activities against three cancer cell lines (mcf7, hepg2 , wehi164) and one normal cell line (mdbk). some plants showed cytotoxic activities. the extract of ferula szowitsiana root, which proved to be the most active, was chosen for further phytochemical studies. the major compounds of the most potent ...
Background : Streptococcus mutans is a major cause of dental caries and tooth damage. The purpose of this study was to evaluate the effect of the Stevioside and Stevia rebaudiana leaf extracts on the growth of Streptococcus mutans. Materials and Methods: In this study, the aqueous and acetone extracts of Stevia rebaudiana were extracted by the maceration method, and methanol and ethanol extract...
Background: This study was devoted to assessing the inhibitory potential of acetone, methanol, and ethanol extracts of Acroptilon repens against disease-associated enzymes, as well as their antioxidant/antibacterial activity and phytochemical composition. Methods: Comparative assessment using various antioxidant evaluation methods, including ferric reducing antioxidant power, scavenging ability...
the subject handled in this study is the determination of antioxidant activities of extracts obtained from the urginea maritima (l.) baker plant’s leaves and tubers. extractions which were obtained using various solvents as methanol, ethanol, acetone and benzine. the antioxidant activity of the extracts was determined using β-karotene-linoleic acid system. moreover, the free radical scavenging ...
In order to search for novel bioactive substances from marine organisms, we investigated the acetone extract of the soft coral Nephthea chabrolii collected at San-Hsian-Tai, Taitong County, Taiwan. From this extract three new 19-oxygenated steroids, nebrosteroids N-P (1-3) were isolated. The structures of these compounds were elucidated by extensive spectroscopic analyses.
Fifteen plant species were collected from the Nelspruit Botanical Garden based on a list of plants provided by Phytomedicine Programme at the University of Pretoria and their ethnopharmacological information. Hexane, dichloromethane (DCM), acetone and methanolic extracts were screened for antimycobacterial activity against Mycobacterium smegmatis. The acetone extract of Milletia stulhimannii wa...
Introduction: It is well known that marine microorganisms have been recognized as an important and untapped resource for novel bioactive compounds. Actinomycetes are gram positive bacteria showing a filamentous growth. They are a group of organisms widespread in nature and play a significant role in the future of drug development. Materials & Methods : Marine bacteria strains of Streptomyces ...
Andrographis macrobotrys Nees is an extensively utilized Indian traditional medicine to treat several human and livestock disorders. The present investigation was designed to evaluate the antibacterial, antifungal potentialities and phytochemical screening of the different leaves and stem extracts of Andrographis macrobotrys belongs to the family Acanthaceae. Methanol, ethanol, chloroform, acet...
