The reaction was masrua by adding 0. Robert Peter Biney contributed to in vivo antioxidant assays, in vitro antioxidant assays, and drafting and correction of the manuscript. Retrieved from ” https: Seed is sown in flat trays filled with river sand and covered with a thin layer of sand or compost.

Peak values and labels are available in Table 1 and Figure 9. An agent that augments NO production or the downstream effects of subeffective doses of L -arginine or sildenafil can reverse the anticonvulsant effect due to the possible induction of NO-induced excitotoxicity. Tested concentrations of MAE and ascorbic acid showed an appreciable reduction in the formation of thiobarbituric acid-reactive species from the yolk substrate Figure madrua c.

The wood is usually small-sized and used for mortars, tool handles, small furniture and posts. Capparaceae has been used for a myriad of therapeutic benefits in the West African subregion [ 6 — 8 ]. The larvae of a number of butterfly species feed on the leaves. The foliage is considered in many countries as good forage, especially for sheep and goats but in other countries, including Gambia, it is considered poisonous.

Even so, it is not likely to be threatened with genetic erosion. Irrespective of these claims, there is currently little scientific evidence to support this traditional use.

Pretreatment with MAE showed increased activity of these enzymes, which suggests that MAE may have ability to prevent the deleterious effects induced by free radicals.


From Wikipedia, the free encyclopedia.

Under oxidative stress, the lipid-rich constitution of the brain can undergo lipid peroxidation, which can result in decreased membrane fluidity and angokensis neurotransmission. Additionally, the extract exhibits comparable in vitro and in vivo antioxidant activities that might play a protective role in states of oxidative stress.

In oxidative stress, free radicals such as superoxide anions are generated and overwhelm the normal protective mechanisms and consequently anbolensis to the detrimental effects on brain tissue.

Subscribe to Table of Contents Alerts. Plant Resources of Tropical Africa Introduction. The present study demonstrates that the lipophilic fraction of the stem bark extract significantly reduces pentylenetetrazole-induced seizure outcomes due to interaction with the receptor and nitricoxidergic system. Despite their unpleasant, bitter taste, the leaves are used by African rural tribes during famine periods as a food supplement, and also used as a purgative.

The plant Maerua angolensis DC.

Eric Woode contributed to experimental concept design, data analysis, and interpretation. Taken together, the data support a role for MAE in attenuation of neuronal damage after seizure attacks, in part at least, by inhibition of oxidative stress injuries. New leaves will grow again, sometimes already during the same season. Instar larvae may defoliate a tree completely, but leaves regrow readily.

An appreciable number of current antiepileptic agents modulate receptor or enhance the response of this receptor to the gamma amino butyric acid GABA.

JPG x – 12k – jpg www. Felix Agyei Ampadu contributed to data analysis, interpretation, in vivo antioxidant assays, and in vitro antioxidant assays. As with most species in the family the twigs and branches display prominent lenticels. In Senegal the leaves are eaten as well, but use of the leaves as a condiment is more widespread.

A decrease in the activity of superoxide dismutase and catalase could result in the decreased removal of superoxide and hydrogen peroxide radicals, which brings about harmful events that can lead to the neuronal tissue damage.

Maerua angolensis is widely spread in savannahs with a preference for sandy soils, from sea level up to m altitude.

Ascorbic acid was used as the standard antioxidant. Decoctions of the leaves are given to children suffering amoebic dysentery or jaundiceand to treat rheumatism, stomach-ache, epilepsy and diarrhoea, while decoctions of the bark are used to treat malaria and as an aphrodisiac.


Maerua angolensis is widely distributed in continental tropical Africa but is absent in some countries with a high rainfall. Superoxide Anion Scavenging Activity The superoxide anion scavenging activity was measured as described by Robak and Gryglewski [ 13 ]. To further angolensia the possible contribution of GABAergic system in the anticonvulsant activity of MAE, flumazenil, a specific antagonist of the receptor complex [ 25 ], was used in antiseizure mechanistic studies.

Seeds almost globose, c. By extension, elevated levels of NO produced by substrates of the neuronal nitric oxide synthase nNOs system can increase the liability to maerya in the CNS after injection of a proconvulsant agent.

The fragrant, pincushion-like flowers are without petals and are produced in abundance at the beginning of the rainy season.

Maerua angolensis – Useful Tropical Plants

The extract demonstrated an anti-diabetic effect in streptozocin-induced diabetic rats. Only in southern and South Africa it is purposely multiplied and planted. Honeybees feed on the flowers throughout the day.

Cardiac problems are treated in the same way and by wearing the root around the neck as an amulet or angolensus eating the root ash.

Table of Contents Alerts. In PTZ-induced seizures, NO levels are elevated and hence NOs inhibitors have been found to suppress seizure parameters including latency to convulsions [ 22629 ].

Charles Kwaku Benneh contributed to experimental design, plant extraction and FT-IR analysis, pentylenetetrazole-induced seizure, antagonism, NO-cGMP mechanism, in vivo antioxidant assays, in vitro antioxidant assays, and drafting and correction of the manuscript.

The treat ulcers dressings with pounded leaves are applied.
