The water fraction of hydroacetonic extract showed the most potent antioxidant activity 6. The leaves are applied externally to bring healing to the body – they are considered antiseptic and vulnerary. Inflorescence an almost spherical terminal and axillary head, up to 15 mm in diameter, many-flowered; peduncle 2—3.
Also more research needed to evaluate the potential effectiveness of the crude extracts as the antimicrobial agents. All the reactions were performed in triplicate. In fact, ferrous ions can precipitate the formation of oxygen radicals and either initiate or take part in peroxidative process Dixit and Kar, Stem gall infection of Guiera senegalensis is very common, and aphids are sometimes present, protected by ants, but other pests or diseases are rare.
It can thus be found flowering and fruiting almost all year long.
Handbook of Natural Toxins6: The yield of aqueous decoction and hydroacetonic extracts was determined. A methanolic leaf extract showed significant dose-dependent inhibition of contraction by acetylcholine of isolated rat trachea.
This disagreement could be explained by the fact that the present study used the aqueous extract of the leaves while Ref. The means of three values were obtained, expressed as mmol of ascorbic acid equivalent per g of extract or fraction antioxidant content mmol AEAC g -1 extract or fraction. Retrieved from ” https: Nine gallotannins with a quinic acid core and two condensed tannins senegalensus and epigallocatechin gallate have been isolated so far.
It is capable of colonizing tracts of land, which might otherwise be bare, to form pure stands[ ].
Furthermore, several biological effects such as antioxidants abilities, and anti-inflammatory effects are attributed to flavonoids and phenolic compounds in medicinal plants [ 27 ]. Crushed leaves are mixed with tamarind pulp and eaten as a laxative and appetizer. The leaves are applied to skin infections and in poultices on inflammatory swellings and for guinea-worm; they have been applied to tumours to maturate them and as a treatment for skin-diseases[ ].
Dried leafy twigs are burnt in stalls or pens to repel flies and biting insects around domestic animals. These extracts contain polyphenols compounds that can scavenge free radical s, chelate metal ions and inhibit the lipid peroxidation activity.
Thus, we hope that the important phytochemical compounds identified by our study in the Gswill be helpful in treating different diseases of this particular region of Africa, and may be in other regions. It, therefore, is important to investigate traditional medicinal plants to assess, following scientific methodologies, their properties, safety, and efficiency of treatment, and senegaldnsis optimum dose [ 21 ].
Guiera – Wikipedia
These antimicrobial properties were credited to the crude methanolic extracts of Gs [ 8 ]. Correlation between antioxidant activity and anti- lipid peroxidation activity. The reducing power is generally associated with the presence of reductones, which exerts antioxidant action by breaking the free radical chain by donating a hydrogen atom Prasad et al. DPPH method is independent of the substrate polarity.
Indication of a yellow color shows the presence of flavonoids in each extract [ 11 ]. A chloroform extract of the roots exhibited a pronounced antimalarial activity against Plasmodium falciparum in vitro and displayed low toxicity. The major tannin in all plant parts is 3,4,5-tri-O-galloylquinic acid.
It prefers dry or moist soil and can tolerate drought. Anti-angiogenic, antioxidant and xanthine oxidase inhibition activities of the mushroom Phellinus linteus.
Guiera senegalensis is one of the most popular west African medicinal plants, and is used to treat a wide variety of diseases. From this result, we can conclude that the Gs leaves extract is apparently not toxic. Folin-Ciocalteu reagent, aluminium trichloride AlCl 32,2-diphenylpicrylhydrazyl DPPHxanthine, gallic acid, quercetin, allopurinol, trichloroacetic acid, tween 40, 2-thiobarbit uric acidXanthine oxidase E.
Roots have been observed to grow within 2 weeks after layering. Grows wild in light, dry soils.

J Plant Biochem Physiol 4: The plant is a source of 3,4,5-Tri-O-galloylquinic acid, a hydrolysable tannin classified as a natural product with anti-HIV activity and a DNA polymerase inhibitor. Views Read Edit View history. Journal of Pharmacognosy and Phytotherapy 5: Guiera senegalensis occurs in shrub savanna, tree savanna and fallow land, from sea-level up to m altitude.
The shrubs resprout profusely from senegalensiss base and help to fix the soil during the eenegalensis season. However, in a different experiment, petroleum ether, chloroform and methanol extracts from the leaves did not show significant in vivo antimalarial activity in mice experimentally infected with Plasmodium berghei, when intraperitoneally administered.
