OBJECTIVE To evaluate methanolic, ethanolic, acetone and aqueous extracts from different parts of Eurycoma longifolia (E. longifolia) (leave, stem, and root) for antibacterial activity against Gram-positive and Gram-negative bacteria and to utilize the leaves and stem parts rather than the root, which is already used for male sexual enhancement in Malaysia. METHODS The study took place in the...

The extracts of 17 spices commonly used in Egypt as food condiments were screened for their antimicrobial activities against 7 standard microbial strains (S. aureus, B. subtilis, E. coli, P. aeruginosa, S. typhi, C. albicans and A. niger). Among the tested alcoholic extracts only 3 (clove, thyme and cinnamon) showed broad spectrum antimicrobial activities. Garlic juice too showed broad spectrum...

Background: Coriandrum sativum L. has been recommended for relief of insomnia in Iranian traditional medicine. However, no pharmacological studies have yet evaluated its sedative effects. The aim of this study was to determine if extracts and essential oil of coriander seeds have sedative-hypnotic activity. Methods: The aqueous or hydro-alcoholic extracts or essential oil of coriander seeds (10...

Myrtle (Myrtus communis L.) leaf, stem and berry extracts were prepared to examine the total phenolics, flavonoids and condensed tannins contents. The antioxidant activities of crude extracts, ethyl acetate fraction, butanolic fraction, tannins and anthocyanins from these parts of plant were evaluated in vitro using reducing power and DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging...

The antimicrobial efficiency of Phyllanthus amarus Schum. and Thonn, medicinal plants (leaf extracts), was examined using ethanol and chloroform as solvents and tested against human pathogens ; Staphylococcus aureus, Escherichia coli, and Candida albican, using the agar well-diffusion method and minimum inhibitory concentration. The result of the phytochemical analysis of the plant showed that ...

BACKGROUND In South Africa, Calpurnia aurea (Ait.) Benth is used to destroy lice and to relieve itches, to destroy maggots and to treat allergic rashes, particularly those caused by caterpillars. Antioxidants play an important role protecting against damage by reactive oxygen species. Plants containing flavonoids have been reported to possess strong antioxidant properties. METHODS The antibac...

Bacterial resistance to antibacterial drugs in the treatment of some bacterial infections has become a menace, therefore causing untold health challenges to patients. The antibacterial activity of hot and cold water and ethanolic extract of the leaf and stem bark of Irvingia gabonensis against Escherichia coli and Staphylococcus aureus was evaluated using agar-well diffusion and agar dilution m...

The present study was aimed to evaluate the antibacterial activity of Amorphophallus campanulatus (family: Araceae) commonly known as jangli suran. The root, stem and leaf of A. campanulatus, extracted successively with polar (aqueous, methanol), dipolar (acetone) and non polar (chloroform) solvents, yielded more phyto compounds in case of root followed by stem and leaf. The extracts were asses...

This study was conducted to evaluate the effect of different extraction solvents, including hydro-alcoholic (H-A), ethanolic (Et-OH), and methanolic (Me-OH), on chemical composition and synergistic antibacterial activity of Frangula alnus extract against Staphylococcus aureus and Escherichia coli. The chemical composition of the F. alnus bark extract was eval...
