Journal ArticleDOI
A sensitive and quick microplate method to determine the minimal inhibitory concentration of plant extracts for bacteria
TL;DR: A micro-dilution technique was developed using 96-well microplates and tetrazolium salts to indicate bacterial growth and was useful in screening plants for antimicrobial activity and for the bioassay-guided isolation of antimicrobial compounds from plants.
Journal ArticleDOI
Which extractant should be used for the screening and isolation of antimicrobial components from plants
TL;DR: An arbitrary scoring system was developed to evaluate the above parameters for the different extractants and acetone gave the best results with these plants with an arbitrary value of 102.
Journal ArticleDOI

Journal ArticleDOI
Biological activity of five antibacterial flavonoids from Combretum erythrophyllum (Combretaceae)
TL;DR: This is the first report of biological activity with several of these antibacterial flavonoids, i.e. apigenin; genkwanin; rhamnocitrin; quercetin-5,3'-dimethylether;rhamnazin, which had a higher anti-inflammatory activity than the positive control mefenamic acid.
