The present study was to estimate the in vitro anthelminthic effect of the aqueous extract of the trunk barks of Acacia nilotica var. adansonii, plant used in this traditional medicine against gastro- intestinal parasites. Trunk barks of Acacia nilotica var. adansonii were used as plant material, eggs and adults worms of Haemonchus contortus were the animal material used. The adult worms and the eggs were put in contact with increasing concentrations of the extract. A phytochemical screening of the plant material was also performed. This study revealed the presence of chemical groups with anthelminthic properties such as tannins, triterpenics, saponosides in the aqueous extract. The vermicide effect was indicated by the lethal concentration of 50% (LC50) of adult worms equal to 1.28 mg / mL compared to the levamisole LC50 which was 3.25 mg / mL. The rate of eggs hatching inhibition was 93.84 % at the extract concentration of 0.1 mg / mL. Anthelminthic properties of Acacia nilotica var. adansonii would be real, which justifies its use in traditional medicine for the treatment of gastrointestinal parasites

Purpose – The purpose of this paper is to discuss applied statistical design of experiment (DOE) to optimize the process of dyeing in natural fiber through the multidisciplinary photoacoustic technique. Design/methodology/approach – First, the spectroscopy analysis of the dyestuffs was carried out based on the 23 factorial design. Second, the DOE was utilized to find which process variables were most significant in the absorption band’s intensity of the dye. Finally, the impregnation optimization of fiber was carried out based on response surface methodology. Findings – The results showed that the dyeing process is more efficient for samples with lower level of dye concentration and dyeing procedure time. The statistical study of the effect of each preparation factor suggested that the composition of the colors has a pronounced influence in the fiber dyeing. Originality/value – Using the DOE and photoacoustic response in the present work was clearly found and proposes a less expensive dyeing process and that reduces the harmful impact to environment.

Acacia niloticais a plant species that is almost ubiquitously found in different parts of the world. Various preparations of it have been advocated in folk medicine for the treatment of tuberculosis, leprosy, smallpox, dysentery, cough, ophthalmia, toothache, skin cancer as astringent, antispasmodic, and aphrodisiac since immemorial times. The present study investigates the antibacterial, antifungal, antiviral, and immunomodulatory potential of hot aqueous extract (HAE) ofAcacia niloticaleaves. On dry matter basis, the filtered HAE had a good extraction ratio (33.46%) and was found to have carbohydrates, glycosides, phytosterols, phenolic compounds, saponins, and flavonoids as major constituents. HAE produced dose dependent zone of inhibition againstKlebsiella pneumoniae, Pseudomonas aeruginosa, E. coli, Bacillus cereus, Staphylococcus aureus, and Streptococcus uberisand fungal pathogensAspergillus nigerandAspergillus fumigates; however, no antiviral activity was recorded against IBR virus. HAE ofA. niloticarevealed both proliferative and inhibitory effects on the rat splenocytes and IL-10 release depending on the dose. Detailed studies involving wide spectrum of bacterial, fungal, and viral species are required to prove or know the exact status of each constituents of the plant extract.

AbstractAcacia niloticais a widely used plant in traditional medical practice in Northern Nigeria and many African countries. The aim of this study was to determine the toxicological effects of a single dose (acute) and of repeated doses (sub-acute) administration of aqueous extract ofA. niloticaroot in rodents, following our earlier study on antiplasmodial activity. In the acute toxicity test, three groups of Swiss albino mice were orally administered aqueous extract ofA. nilotica(50, 300 and 2000 mg/kg body weight) and signs of toxicity were observed daily for 14 days. In the sub-acute toxicity study, four groups of 12 rats (6 male and 6 female) were used. Group 1 received 10 ml/kg b.w distilled water (control), while groups 2, 3 and 4 received 125, 250 and 500 mg/kg b.w of the extract, respectively, for 28 consecutive days by oral gavage. Signs of toxicity/mortality, food and water intake and body weight changes were observed. Biochemical parameters were analysed in both plasma and liver homogenate. In the acute and sub-acute toxicity studies, the extract did not cause mortality. A significant reduction in the activity of lactate dehydrogenase was observed at 250 and 500 mg/kg b.w, while alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities were significantly higher than control values at 500 mg/kg b.w. The aqueous extract ofA. niloticawas found to be safe in single dose administration in mice but repeated administration of doses higher than 250 mg/kg b.w of the extract for 28 days in rats may cause hepatotoxicity.

Adsorption Data

Adsorption of the hazardous dye malachite green (MG) by Acacia nilotica (AN) waste was investigated. Batch process variables for the adsorption of MG by AN were optimized. The mechanisms involved in the adsorption of MG by AN were explored using isotherms and kinetic models. The thermodynamic parameters were calculated to determine the spontaneity and thermal nature of the MG adsorption reaction. The maximum equilibrium adsorption capacity of AN was found to be 113.26 mg/g at 30 °C. The MG adsorption data revealed that AN adsorbs MG by multilayer adsorption, as shown by the better fit of the data to the Freundlich and Halsey models (R2 = 0.99) rather than to the Langmuir model. Multilayer adsorption involves physisorption, which was confirmed by the E value (mean free energy of adsorption) of the Dubinin–Radushkevich model (6.52 kJ/mol). Surface diffusion was found to be the main driving force for MG adsorption by AN. The MG adsorption reaction was endothermic, based on the enthalpy, and was controlled by the entropy of the system in the T1 temperature range (30 to 40 °C), while the opposite trend was observed in the T2 range (40 to 50 °C). Moreover, MG adsorption by AN was found to be nonspontaneous at all temperatures.
