ABSTRACT
Gum Arabic (Acacia nilotica L.) is a respected plant that has many nutrients and curative practices. It hinders, improves, or manages many disorders. The radio-protective activity of Acacia nilotica was investigated against γ-rays-induced testicle damage in rats. Twenty-four rats were correspondingly distributed into 4 groups; control, Acacia nilotica (15mg/kg, daily for 30 days), γ-irradiated (5Gy γ-rays, single dose) and Acacia nilotica plus γ-rays treated groups. The plasma testosterone and total antioxidant status (TAS) were estimated. Lipid peroxidation; malondialdehyde (MDA), reduced glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), also glutathione peroxidase (GPx), catalase (CAT), tumor necrosis factor-α (TNF-α) with interleukin-1ß (IL-1ß), were determined in the testicle tissues. A testis weight, sperm count and motility, peripheral-blood and bone-marrow micronuclei (PMN and BMN), and frequency of chromosomal aberrations (CAs) were scored. A significant decline in the levels of plasma testosterone with TAS observed in the γ-irradiated rats. The results also showed significantly increased levels of testicle MDA, inflammatory markers, PMN, BMN and CAs frequencies and decrease in testes weight, sperm count and motility and levels of testicle antioxidants markers in gamma irradiated group. All these biochemical and fertility indices results were significantly enhanced in the Acacia nilotica plus γ-rays treated groups. However, the possible alleviate activity of Acacia nilotica on γ-rays-induced testicle injury in rats has not previously conversed, and this is the topic of this study.

A. nilotica possesses various medicinal properties as per classical Unani texts such as astringent, tonic, wound healing, aphrodisiac, expectorant, resolvent, and antispasmodic. In vivo, in vitro, and clinical studies from the published articles validate the fact that A. nilotica is a potential source of various bioactive compounds having various pharmacological properties and therapeutic uses. The various pharmacological activities are anti-inflammatory, analgesic, antibacterial, anticancerous, antidiabetic and antihypertensive properties. This review concludes that the Unani medicinal effects of A. nilotica are proven by scientific studies.
ABSTRACT
Aims:This research was carried out to determine the antibacterial activity of Acacia nilotica stem bark extract and bioactive fractions against the test bacteria (Staphylococcus aureusand Escherichia coli). Place and Duration of Study:Acacia niloticawas collected within Aliero town, Kebbi State, Nigeria between April and September, 2017. Methodology:The crude and bioactive fractions were obtained using soxhlet extraction and column chromatographic methodrespectively. The qualitative phytochemical screening was conducted to detect the presence of some phytochemical constituents in the crude extract and fractions. The antibacterial activity was determined at various concentrations (10, 50, 100, 150 and 200mg/ml) using disc diffusion method Results:The crude antibacterial activity indicated that ethanol extract showed higher activity than the n-hexane extract with 14.0±0.00 and 12.0±0.00 mm zones of inhibition compared with the control drug (10μg Ciprofloxacin drug), which showed 14.0±0.00 and 13.0±0.00 mm zone of inhibition against the test bacteria. The MIC and MBC values determined for ethanol extracts against the test bacteria was 12.5 mg/ml and 25 mg/ml, while the MIC and MBC values obtained for n-hexane extracts were 25 and 50 mg/ml against the test bacteria. The bioactive fractions (Yellow, Purple and Blue Black Fractions) tested against the test bacteria showed higher activity compared with the crude extract. The phytochemical properties of the plant crude extract and the bioactive fractions indicated the presence of phenol, tannins, alkaloids, saponins, flavonoids, terpenoids, steroids and glycosides and this attributed to the high antibacterial activities of 17.0±0.00and 16.0±0.00mm showed by the fractionsagainst Staphylococcus aureus and 15.67±and 14.0±0.00mm against Escherichia coli respectively. Conclusion:Acacia niloticacrude extract and fractions exhibited antibacterial activity which was comparable to the standard drug ciprofloxacin.

ABSTRACT
The herbal extracts have been effectively tried in the treatment and prevention of many oral diseases. Aim: The aim is to assess the antimicrobial efficacy of Acacia nilotica, Murraya koenigii L. Sprengel, Eucalyptus hybrid, Psidium guajava extracts and their combinations on Fusobacterium nucleatum (Fn) and Porphyromonas gingivalis (Pg). Materials and Methods: The extraction process was carried out by Soxhlet apparatus using ethanol as solvent. The combinations of the four plant extracts were prepared by combining an equal quantity of 10% solution of each of the four plant extracts. The antimicrobial efficacy testing of the plant extracts and their combinations on Fn and Pg was performed using agar well diffusion method. Columbia 5% of sheep blood agar plates were used for antimicrobial efficacy testing under anaerobic conditions. The qualitative assay was carried out to identify the various phytochemical constituents. Dimethyl sulfoxide and 0.2% chlorhexidine acted as negative and positive controls, respectively. The mean diameter of inhibition zone between different categories was compared using one-way analysis of variance. Results: All the individual plant extracts and their double, triple, and quadruple combinations were effective in inhibiting the growth of these bacteria. However, 0.2% chlorhexidine produced the highest mean diameter of inhibition zone. Conclusion: The plant extracts in combinations offer enhanced antimicrobial efficacy due to their synergistic action besides slowing the development of bacterial resistance. Hence, these extracts in combinations could be used tried as effective alternates to chlorhexidine.
ABSTRACT
Background: The rise in disease incidence, increased resistance of pathogenic bacteria to currently used antibiotics and chemotherapeutics, opportunistic infections in immunocompromised individuals, and financial considerations in developing countries necessitates alternate preventive and treatment strategies for oral diseases. Objective: The objective of the study is to assess the antimicrobial efficacy of triple and quadruple combinations of Acacia nilotica (AN), Murraya koenigii (Linn.) (MKL) Sprengel, Eucalyptus (Euca), and Psidium guajava (PS) on primary plaque colonizers. Materials and Methods: The phytochemicals in four plants were extracted using Soxhlet apparatus. The dried extracts were diluted with dimethyl sulfoxide (DMSO) to prepare stock solutions (100 mg/ml) of each plant. The triple and quadruple combinations were prepared after mixing equal quantities of stock solutions from each plant extracts. The antimicrobial efficacy testing was done on Streptococcus mutans, Streptococcus sanguis, and Streptococcus salivarius using agar well diffusion method. Chlorhexidine of 0.2% composition and DMSO were used as positive and negative controls, respectively. The mean diameter of inhibition zone between different categories was compared using one‑way analysis of variance. Results: The combination of AN + MKL Sprengel + Euca + PS produced the highest mean diameter of inhibition zone (23.5 ± 2.17 mm) against S. mutans. The combination of AN + MKL Sprengel + Euca produced the maximum antimicrobial efficacy against S. sanguis (19.83 ± 1.33). Conclusion: All the triple and quadruple combinations of the plant extracts offered antimicrobial benefits either superior or comparable to 0.2% chlorhexidine against S. mutans, S. sanguis, and S. salivarius.
ABSTRACT
Evaluation of hypoglycaemic activity of ethyl acetate and n-butanol fractions of Acacia nilotica on alloxan induced diabetic Wistar rats has been investigated. Two doses of the ethylacetate fraction 50 and 100 mg/kg was administered. As regard to 50mg/kg caused a significant (P<0.05) reduction in the blood glucose levels when compared with control at 3,5,7,9 and 12 days of treatment with percentage glycaemia change of 49.1,54.8,60.5, 58.8 and 69.7 respectively. However, the dose of 100mg/kg ,there was a significant decrease (p<0.05) at 3 5 7, 9 and 12 days treatment when compared to control untreated with percentage glycaemia change of 50.1,56.8, 52.8, 69.9 and 59.6 . Also two doses of n-butanol, 100 and 200 mg/kg fraction was administered to the diabetic rats. The dose of 100 mg/kg, there was a significant decrease (p<0.05) after 7 and 12 days of treatment when compared to untreated control. As regard the dose of 200 mg/kg, there was a significant decrease ( p<0.05) at 3, 5 ,7,9 and 12 days of treatment when compared to control untreated with percentage glycaemic change of 20.7,35.3,52.3, 44.2 and 40.9 respectively. The preliminary phytochemical screening revealed the presences of saponin, flavonoid, tannin and alkaloid. The median lethal dose (LD50) in mice was calculated to be 471.2 mg/kg bodyweight. This result suggests that the Ethylacetate and n-butanol fractions of leaves methanolic extract of Acacia nilotica possess antidiabetic effects on alloxan - induced diabetic Wistar rats.
ABSTRACT
Acacia nilotica proteinase inhibitor (AnPI) was isolated by ammonium sulphate precipitation followed by chromatography on DEAE-Sephadex A-25 and resulted in a purification of 10.68-fold with a 19.5% yield. Electrophoretic analysis of purified AnPI protein resolved into a single band with molecular weight of approximately 18.6+1.00 kDa. AnPI had high stability at different pH values (2.0 to 10.0) except at pH 5.0 and are thermolabile beyond 80°C for 10 min. AnPI exhibited effective against total proteolytic activity and trypsin-like activity, but did not show any inhibitory effect on chymotrypsin activity of midgut of Helicoverpa armigera. The inhibition kinetics studies against H. armigera gut trypsin are of non-competitive type. AnPI had low affinity for H. armigera gut trypsin when compared to SBTI. The partially purified and purified PI proteins-incorporated test diets showed significant reduction in mean larval and pupal weight of H. armigera. The results provide important clues in designing strategies by using the proteinase inhibitors (PIs) from the A. nilotica that can be expressed in genetically engineered plants to confer resistance to H. armigera.
ABSTRACT
Rho iso-alpha acids-rich extract (RIAA) from Humulus lupulus (hops) and proanthocyanidins-rich extracts (PAC) from Acacia nilotica exert anti-inflammatory and anti-diabetic activity in vitro and in vivo. We hypothesized that a combination of these two extracts would exert enhanced effects in vitro on inflammatory markers and insulin signaling, and on nonfasting glucose and insulin in db/db mice. Over 49 tested combinations, RIAA:PAC at 5:1 (6.25 microg/mL) exhibited the greatest reductions in TNFalpha-stimulated lipolysis and IL-6 release in 3T3-L1 adipocytes, comparable to 5 microg/mL troglitazone. Pretreatment of 3T3-L1 adipocytes with this combination (5 microg/mL) also led to a 3-fold increase in insulin-stimulated glucose uptake that was comparable to 5 microg/mL pioglitazone or 901 microg/mL aspirin. Finally, db/db mice fed with RIAA:PAC at 5:1 (100 mg/kg) for 7 days resulted in 22% decrease in nonfasting glucose and 19% decrease in insulin that was comparable to 0.5 mg/kg rosiglitazone and better than 100 mg/kg metformin. RIAA:PAC mixture may have the potential to be an alternative when conventional therapy is undesirable or ineffective, and future research exploring its long-term clinical application is warranted.
