Allergic diseases are constantly growing, however the efficiency of classical treatments is not total. Thus, new therapeutic tools are considered such as phytotherapy. The objective of this study was to demonstrate the effect of the aqueous extract of Moringa oleifera in mice. The phytochemical study revealed the presence of poly terpenes/sterols, polyphenols, flavonoids, tannins and alkaloids but also the absence of quinones and saponosides. The acute toxicity study at a single dose of 2000 mg/kg body weight (bw) by the oral route revealed that the aqueous extract of Moringa oleifera is not toxic and would have an oral LD50 greater than to 2000 mg/kg bw. The anti-allergic effect of Moringa oleifera leaf Total Aquous Extract (E.T.A.) was evaluated by observing the number of scratching in allergic mice treated orally with two different doses of this extract. A reduction of the number of scratching in mice treated with the extract was observed. This was confirmed by hematological analysis where a considerable increase in the number of immune cells and a decrease in the recruitment of these cells to inflammatory sites were observed. This confirms that the aqueous extract of Moringa oleifera has a dose-dependent antiallergic activity

The determination of mechanical properties of unshelled Moringa oleifera seeds was studied under compression test at varying orientations and moisture contents for postharvest equipment design. A completely randomized block design (CRBD) was applied in designing the experiment. The impact of varying moisture content levels of (10.25, 17.33, 24.47, and 32.34% dry basis) on the applied force at bio-yield and rupture, deformation, energy at rupture, crushing strength, and elastic modulus of the seed samples were investigated. Polynomial functions of the 2nd order with coefficients of correlation ranging between 0.642 ≤ R2 ≤ 0.999 gave the best fit and described the resulting relationships between the studied properties with respect to moisture levels at the two loading axes. Results obtained showed that the seed samples had maximum values of 80.3 N, 110 N and 257.2 J, for bio-yield force, rupture and rupture energy respectively at (10.25% d.b., in the horizontal orientation; whereas minimum values of 31.5 N, 54.9 N and 51.3 J for bio-yield force, rupture force and rupture energy occurred at (32.34% d.b.) respectively in the vertical orientation. Also, the maximum compressive strength of 5.8 N mm-2 in the horizontal orientation of the seed samples at 10.25% d.b. whereas the minimum compressive strength (2.5 N mm-2) occurred in the vertical orientation at 10.25% d.b. moisture content. The sample exhibited less resistive strength to crushing in the horizontal position as the moisture increased; whereas in the vertical position, the cell’s vertical edges provide some form of shield against external pressure which resulted in increased crushing resistance per contact area of the sample.

Abstract An enhanced and different method for the active coagulant agent extraction from Moringa Oleifera seeds powder (MOSP) was established and compared to the conventional extraction method in distillate water. In the improved method, MOSP were extracted using sodium chloride as solvent at different concentrations to extract more coagulant agent from Moringa Oleifera and enhance coagulation activity. In this study, MOSP were initially processed and oil content was removed to minimize coagulant concentration usage (MOSP-EO). Moringa Oleifera seeds powder was characterized by both X-ray and FTIR analysis. Ultrasound treatment as well was considered as an additional treatment for MOSP-EO to investigate its effect on coagulant agent extraction process improvement. Coagulation/flocculation experiments were conducted to assess coagulant extraction performance realized through various conditions. The effect of coagulant dosage, solvent concentration and ultrasound exposition duration were investigated for a real effluent of municipal wastewater treatment. Among the three studied NaCl concentrations, 1.0 M was found to be the best solvent concentration for high turbidity removal of more than 97% using 140 mg/L of MOSP-EO compared to extraction in distillate water 88% using 170 mg/L of the same coagulant. NaCl 1.0 M demonstrated the best performance in biochemical oxygen demand (BOD5) removal as well, where more than 98% of municipal wastewater initial BOD5 was eliminated. Mixing MOSP-EO assisted with ultrasound waves at different treatment periods did decrease the active coagulant agent extraction and thus showed its inconvenient for Moringa Oleifera coagulation activity usage.

Moringa oleifera es una especie con gran importancia alimenticia. El objetivo fue determinar el efecto de la poda sobre la producción de biomasa y contenido proteico en moringa. Plantas de tres años de edad fueron seleccionadas de acuerdo a la similitud entre altura y diámetro basal. El diseño experimental fue con tres tratamientos y cuatro repeticiones. Los tratamientos fueron podas a 0.75, 1.00 y 1.50 m de altura. Se midieron variables de longitud de brotes, número de brotes, número de hojas y producción de biomasa a los cuatro meses. Paralelamente se determinó el contenido de humedad, ceniza y proteína en hojas. Se encontraron diferencias estadísticas (Tukey, p<0.05) en el crecimiento y supervivencia de los brotes, siendo los tratamientos 1.00 m y 0.75 m de mayor altura para la primera y segunda poda. El T3 presentó 83.31% de humedad, 16.85 % de proteína y 12.3 % de ceniza en la primera poda. No se encontraron diferencias estadísticas (Tukey, p>0.05) en la producción de biomasa, ni tampoco en el contenido de proteína en hojas. Se concluye que, moringa es resistente a podas a baja altura. Las podas incrementan la producción de biomasa y facilitan la cosecha en moringa

AbstractThe impact of gold mining activities on the Lom River in Wakaso (Adamawa Cameroon) and the potential of Moringa Oleifera seeds for the removal of pollutants from wastewater is evaluated on this paper. Water samples were collected for physicochemical (hydrogen potential, electrical conductivity, turbidity and suspended solids) and chemical (major ions and heavy metals) analyses. To evaluate the effect of mining activities on waters and sediments, a combination of multivariate statistical analysis (MSA) and methods to assess the sediment quality was used. The restorative effect of Moringa oleifera seeds was studied with the determination of the maximum removal efficiencies and the maximum adsorption capacities. The results of the physicochemical characterization of waters showed that these waters were slightly acidic to slightly basic (6.12–8.12), weakly conductive (185.8–584.1 μS cm−1), turbid (345–801NTU) and had high content of suspended solids (167–700 mg L−1). The average concentrations of studied heavy metals (Ni, Cd, Fe, Mn, As and Hg) in waters exceeded the limits recommended by the World Health Organization (WHO) standards. Physicochemical characterization of sediments revealed that they were acidic to neutral (5.95–6.80) and organic matter (OM) content ranged from 11.11 to 15.78%. The concentrations of studied trace metals (Ni, Cd, Fe, Hg, Mn and As) in sediments were below the limits recommended by the WHO except for Cd and Hg. The study of the capacity of Moringa oleifera seeds to remove pollutants in waters showed that 54% of the electrical conductivity, 80% of turbidity and 94% of suspended solids were reduced. The maximum removal efficiency of 91.66, 92.30 and 24.48 and the maximum adsorption capacity of 2.4, 2.6 and 16.6 mg g−1were observed for Cd (II), Hg (II) and Fe (II), respectively. Thus, the Moringa oleifera seeds which are locally available natural bio-adsorbent exhibit attractive property to treat wastewater.
