Ethanol and water extracts of Icacina trichantha leaves were screened for their phytochemicals and antimicrobial activity against Escherichia coli, Staphylococcus aureus, streptococcus spp, Candida albicans and Klebsiella pneumonia. The result indicated that alkaloids, tannins, saponins, and phenols were present in the plant part. Both the ethanol extract and the water extract were active again...

Extracts from ‘Zhéri’ and ‘Hicaznar’ varieties of pomegranate, Punica granatum L., were obtained by subjecting powdered peels to extraction using water, water/ethanol (1:1; v/v), ethanol, acetone heptane. Using the agar diffusion assay, extracts with water and/or ethanol shown display significant antimicrobial activity diameters inhibition zones up 20 mm. Ethanolic extracts, which most active, ...

In this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of Nerium oleander L. grown in the north of Iran by employing various in-vitro assay, i.e. DPPH free radical scavenging, reducing power and total antioxidant capacity through the Mo (VI) reduction. The extracts showed different level...

a vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as dna, proteins and lipids. when free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. therefore, the body should be protected by an enzymatic or no...

The aim of this study was to evaluate the anti-oxidant activity of the flowers of the plant Vernonia cinerea (Family: Asteraceae). Flowers extracts of V. cinerea in different four organic solvents (methanol, hexane, chloroform and ethyl acetate) and water were assayed for antioxidant activity using FRAP assay. All of these extracts were found to possess significant antioxidant activity at 5mg/m...

Background: The purpose of the study was to extract carotenoids from thermophilic bacteria which show efficient antioxidant and protein oxidation inhibition properties, characterize and identify those isolates, extract the carotenoids in different solvents, quantify the carotenoids and perform concentration-dependent and solventdependent quantitative assays validated and analysed by appropriate...

BACKGROUND Nowadays there is a need to find naturally occurring substances from plants with antimicrobial activity as an alternative to available used antibiotics. MATERIALS AND METHODS Salvadora persica (miswak) and Commiphora gileadensis were collected, dried and extracted with either methanol or warm water and the obtained extracts were assessed for their antibacterial activity against 5 d...

BACKGROUND Nearly all cultures from ancient times to the present day have used plants as a source of medicines. As a result, different remedies tended to develop in different parts of the world. Current strategies to overcome the global problem of antimicrobial resistance include research in finding new and innovative antimicrobials from plants. OBJECTIVES To determine the antibacterial activ...
