Anti-nociceptive effects of the hydroethanolic extract of Alysicarpus ovalifolius in rodents
Alysicarpus ovalifolius commonly known as gadagi in Northern Nigeria is claimed to possess tonic effects. Substances that show stimulant properties have demonstrated analgesic effects. This study therefore aimed at investigating the anti-nociceptive effects of the hydroethanolic extract of A. ovalifolius (HEAo) in mice and rats. The activities of the extract on acetic acid induced abdominal writhing, formalin induced...
Elemental contents of some medicinal plants using energy dispersive x-ray fluorescence (EDXRF)
The presence of some elements in ten plants with anti-microbial potency was analysed using x-ray fluorescence technique. The results showed there were nineteen elements in these plants. They all contain Pb, a toxic heavy metal, except one that contains As. K, S, Ca, Fe, Zn, Cu, Co, Ni, Mn and Se elements were identified and their anti-microbial properties were discussed. Key words: Energy dispersive x-ray...
Chemical composition and bioactivity of essential oil from Morinda citrifolia L. fruit
Morinda citrifolia has aroused the interest of several research institutions due to its pharmacological properties. The compounds biosynthesized can be explored as an alternative for control measures of plant pathogens causing leaf lesions in maize. The study aim at evaluating the potential effects of essential oil obtained from ripe fruits of M. citrifolia on Bipolaris maydis and Exserohilum turcicum isolated from...
Healing and topical anti-inflammatory activities of the total aqueous bark extract of Combretum glutinosum Perr. (Combretaceae)
Combretum glutinosum Perrot. Ex DCs (Combretaceae) is a plant used in Senegalese traditional medicine. Its trunk barks are used to treat burns and wounds. The objective of this study was to evaluate the healing effect and topical antiinflammatory activity of the aqueous bark extract of C. glutinosum in second degree burn and croton oil induced ear edema in mice. Phytochemically, the aqueous bark extract of C. glutinosum...
In vitro cytotoxic and anti-herpesvirus properties of jackfruit (Artocarpus heterophyllus Lam., Moraceae) leaf extracts
The jackfruit tree (Artocarpus heterophyllus Lam.) is considered one of the most versatile trees and is used from wood production to traditional medicine. In traditional medicine, leaves are used to treat asthma, wounds and abscesses, and prevent ringworm infection. Several biological activities have been documented for jackfruit extracts confirming its popular use; however, its in vitro cytotoxicity and...
DPPH radical scavenging activity of extracts from Urtica urens (Urticaceae)
In this study, hexane, chloroform, ethyl acetate and methanolic extracts from leaves, stem-bark and root of Urtica urens were evaluated for their antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay. The hexane, chloroform, ethyl acetate and methanolic extracts from leaves of U. urens showed scavenging activity ranging from 7.06±2.52 to 26.01±1.84, 10.86±1.81 to...
