Multi-functional application of Moringa oleifera Lam. in nutrition and animal food products: A review

Research on the use of various parts of the Moringa oleifera Lam. plant (M. oleifera) as a nutritional and neutraceutical resource for human and animal diets has increased in recent years, emanating from the widespread use of the plant in traditional cuisines and medicinal remedies in several regions of the world. Analytical studies have identified M. oleifera as an important source of essential nutrients; rich in protein, essential amino acids, minerals, and vitamins, with a relatively low amount of antinutrients. It is also a rich source of other bio active compounds including flavonoids and phenolic compounds; with several studies detailing demonstrated in vitro and in vivo functional properties, most substantially, antioxidant activities. Moringa oleifera consumption has been reported to improve the health status, feed conversion efficiency, growth performance and product quality of several livestock species, at dietary inclusion rates generally not exceeding 5% of total dry matter intake. Fortification of processed foods with M. oleifera has been reported to increase nutritional value, some organoleptic properties, oxidative stability and product shelf life; with a notable need for further analytical and consumer studies in the development of these products. There is a paucity of literature detailing clinical studies, nutrient bioavailability, toxicity and the mode of action of the bioactive compounds to which the health claims associated with M. oleifera consumption are attributed. Many of these are not yet fully understood; therefore more research in these areas is required in order to fully utilize the potential benefits of this plant in human and livestock nutrition.

Effect of Temperature on the Mobility of Ions

The effect of temperature, between 87 and 250 deg C, on the mobility of protonated amines in helium, air, CO2, and SF6 was studied by ion mobility spectrometry.In helium, the reduced mobility was found to decrease as the temperature was raised, due to an increase in the collision cross section, and was approximately proportional to T-1/2.In CO2, where clustering takes place at low temperatures, raising the temperature led to an increase in the reduced mobility, mainly due to breakdown of the clusters and a decrease in the effective mass of the ion.In air, where only little clustering was observed, the reduced mobility of light ions in creases with the temperature, while for heavy ions the oposite was found.In SF6, like in CO2, the increase of the reduced mobility with temperature was attributed to breakdown of clusters.An expression for the temperature dependence of the reduced mobility in each of these drift gases was determined semiempirically.

Iridium-Catalyzed Regioselective C(sp3)-H Silylation of 4-Alkylpyridines at the Benzylic Position with Hydrosilanes Leading to 4-(1-Silylalkyl)pyridines

The regioselective silylation of C(sp3)-H bonds at the benzylic position in 4-alkylpyridines with hydrosilanes is described. The reaction proceeds in the presence of a catalytic amount of Ir4(CO)12 or Ir(acac)(CO)2, which possess CO as a ligand, or [Ir(OMe)(cod)]2 under 1 atm of CO. After optimizing the reaction conditions, by using other pyridine derivatives, such as 3,5-dimethylpyridine, as additives, the low product yields of 2-substituted 4-methylpyridines were improved markedly.

Zeolite-Catalyzed Isomerization of Aromatic Amines to Methyl-Aza-Aromatics

The scope and mechanism of the isomerization of arylamines to methyl-substituted aromatic heterocycles have been studied.Aniline, toluidines, naphthylamines and m-phenylenediamine all reacted to the corresponding ortho-methyl-substituted aza-aromatiics when exposed to high NH3 pressure and elevated temperature in the presence of acid catalysts.Zeolites with a three-dimensional pore structure, especially H-ZSM-5, showed the best performance.Optimum reaction conditions are around 600 K and 10 MPa.Two mechanisms which had been proposed earlier for this apparent N-ortho C exchange reaction proved untenable.Neither incorporation of the N atom into the aromatic ring nor a mechanism based on an intramolecular Ritter reaction could explain the required high NH3 pressure or the product distribution.Two new mechanisms are proposed which can explain all observations.In both mechanisms, reaction starts with addition of NH3 to the arylamine, followed by ring opening.In one mechanism an alkyno-imine intermediate is formed; in the other mechanism an enamino-imine intermediate is formed through a reverse aldol reaction.In both cases ring closure and NH3 elimination lead to the required aromatic heterocycles.The high NH3 pressure is explained by the need to add NH3 to the aromatic ring, and the high temperature by the need to desorb NH3 from the acid sites.

Co-ordination State of Copper(II) Ion in Cu(O2CMe)2-Pyridine Derivative-Diluent Mixtures; the Steric Effect of the Amine Ligand

Accurate and reproducible ion mobility measurements for chemical standard evaluation

Chemical standards are used to calibrate ion mobility spectrometers (IMS) for accurate and precise identification of target compounds. Research over the past 30 years has identified several positive and negative mode compounds that have been used as IMS standards. However, the IMS research community has not come to a consensus on any chemical compound(s) for use as a reference standard. Also, the reported K0 values for the same compound analyzed on several IMS systems can be inconsistent. In many cases, mobility has not been correlated with a mass identification of an ion. The primary goal of this work was to provide mass-identified mobility (K0) values for standards. The results of this work were mass-identified K0 values for positive and negative mode IMS chemical standards. The negative mode results of this study showed that TNT is a viable negative mode reference standard. New temperature-dependent K0 values were found by characterizing drift gas temperature and water content; several examples were found of temperature-dependent changes for the ion species of several standards. The overall recommendation of this study is that proposed IMS standards should have temperature-dependent K0 values quoted in the literature instead of using a single K0 value for a compound.

Heat capacities of the six dimethylpyridines between the temperatures 10 K and 445 K and methyl-group rotational barriers in the solid state

Heat capacities and enthalpy increments between the temperatures T = 10 K and 445 K were determined for the six dimethylpyridines by adiabatic calorimetry. (Chemical Abstract registry numbers: 2,3-dimethylpyridine <583-61-9>; 2,4-dimethylpyridine <108-47-4>; 2,5-dimethylpyridine <589-93-5>; 2,6-dimethylpyridine <108-48-5>; 3,4-dimethylpyridine <583-58-4>; and 3,5-dimethylpyridine <591-22-0>.) Triple-point temperatures and enthalpies of fusion are reported for each material, and enthalpy increments and entropies relative to those of the crystals at T -> 0 were derived.Lambda-type phase transitions in the crystals were observed for 2,6-dimethylpyridine and 3,4-dimethylpyridine.A small step or “bump” was observed in the heat-capacity-against-temperature curves for 2,6-dimethylpyridine and 2,3-dimethylpyridine.Barriers to methyl-group rotation in the solid state are estimated for each compound and compared with literature values.
