Elemental composition, total fatty acids, soluble sugar content and essential oils of flowers and leaves of Moringa oleifera cultivated in Southern Portugal. Heliyon 2022; 8:e12647. [PMID: 36636210 PMCID: PMC9830163 DOI: 10.1016/j.heliyon.2022.e12647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/31/2022] [Accepted: 12/19/2022] [Indexed: 12/25/2022] Open
Abstract
The evaluation of the elemental content of moringa leaves and flowers by Energy Dispersive X-Ray Fluorescence Spectrometry revealed that the leaves are a good source of some macro (Ca and K) and micronutrients (Mn) beyond the presence of important polyunsaturated fatty acids (PUFAs), essential in human nutrition. Total soluble sugars prevail in the flowers which may be linked to insect attraction and the pollination process. M. oleifera leaves, flowers and seeds essential oils (EOs) were isolated by hydrodistillation. Gas chromatography and gas chromatography-mass spectrometry analysis (GC-MS) showed EOs dominated by alkanes and fatty acids in diverse ratios in the analyzed plant parts. The nutritional characterization of M. oleifera cultivated in Portugal showed some important nutrients to human physiology. Further studies will allow determining if its consumption may overcome the nutritional imbalances of daily modern households, preventing the emergence of hypertension and diabetes.

Gebrai Y, Ghebremichael K, Mihelcic JR. A systems approach to analyzing food, energy, and water uses of a multifunctional crop: A review. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 791:148254. [PMID: 34412387 DOI: 10.1016/j.scitotenv.2021.148254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 05/26/2021] [Accepted: 05/31/2021] [Indexed: 06/13/2023]
Abstract
Multifunctional crops can simultaneously contribute to multiple societal objectives. As a result, they represent an attractive means for improving rural livelihoods. Moringa oleifera is an example of a multifunctional crop that produces nutritious leaves with uses as food, fodder, and a biostimulant to enhance crop growth. It yields seeds containing a water purifying coagulant and oil with cosmetic uses and possible biofuel feedstock. Despite Moringa oleifera's (and other multifunctional crops') various Food-Energy-Water uses, optimizing the benefits of its multiple uses and livelihood improvements remains challenging. There is a need for holistic approaches capable of assessing the multifunctionality of agriculture and livelihood impacts. Therefore, this paper critically evaluates Moringa oleifera's Food-Energy-Water-Livelihood nexus applications to gain insight into the tradeoffs and synergies among its various applications using a systems thinking approach. A systems approach is proposed as a holistic thinking framework that can help navigate the complexity of a crop's multifunctionality. The "Success to the Successful" systems archetype was adopted to capture the competition between the need for leaf yields and seed yields. In areas where there is energy and water insecurity, Moringa oleifera seed production is recommended for its potential to coproduce oil, the water purifying coagulant, and a residue that can be applied as a fertilizer. In areas where food insecurity is an issue, focusing on leaf production would be beneficial due to its significance in augmenting food for human consumption, animal feed, and its use as a biostimulant to increase crop yields. A causal loop diagram was found to effectively map the interconnections among the various uses of Moringa oleifera and associated livelihood improvements. This framework provides stakeholders with a conceptual decision-making tool that can help maximize positive livelihood outcomes. This approach can also be applied for improved management of other multifunctional crops.

Soil-applied selenite increases selenium and reduces cadmium in roots of Moringa oleifera. Sci Rep 2020; 10:20411. [PMID: 33230176 PMCID: PMC7683596 DOI: 10.1038/s41598-020-77350-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2020] [Accepted: 10/29/2020] [Indexed: 11/08/2022] Open
Abstract
Deficiency of selenium (Se) will lead to malnutrition and decreased immune function of the body. There is a common phenomenon of Se deficiency in foods. In this study, different concentrations of sodium selenite (Na2SeO3) were applied to Moringa oleifera grownin soil. The purpose was to explore the feasibility of Se biofortification of M. oleifera root. The effect of exogenous Se on the accumulation of Se and cadmium (Cd) in the roots of M. oleifera was studied by inductively coupled plasma mass spectrometry, and the mechanism of exogenous Se on the accumulation of Se and Cd in the roots was studied by Fourier transform infrared spectroscopy (FTIR) combined with principal component analysis and partial least squares regression analysis. The results showed that Na2SeO3 significantly affected the accumulation of Se and Cd in the roots (p < 0.05). The increase in Se was highest when Na2SeO3 was around 4.0 mg/kg, which increased by 315% compared with the control. The decrease in Cd was the lowest when Na2SeO3 was around 2.0 mg/kg, which decreased by 80% compared with the control. The results of FTIR analysis showed that Na2SeO3 treatment changed the carboxylate, phosphate radical, hemicellulose and protein in roots of M. oleifera, while the increase of Se was related to hemicellulose, protein, polysaccharide and lignin, and the decrease of Cd was related to hemicellulose and protein. The results showed that exogenous Se increased the accumulation of Se and inhibited the absorption of Cd. Therefore, the roots of M. oleifera can be used in Se biofortified products.

Abstract
Purpose To understand trends, awareness, influences and barriers to eye donation in Indian society. Methods This cross sectional study was conducted in Delhi from March 2017 to February 2018. About 10 hospitals collaborated with the Eye Bank under Human Cornea Retrieval Program (HCRP). Eye Bank recruited Eye Donation Counselors (EDCs) to approach family members of the deceased. A pretested questionnaire was used for this study. Irrespective of whether the next of kin of the deceased consented for eye donation or not, the option of participating in the survey was given. Results Out of 473 potential donors identified, 407 (86%) next of kin consented to participate in the study. Of these, 388 (95.3%) were males and 19 (4.7%) were females. About 168 (41%) consented for eye donation and were assigned to donor group, while 239 (59%) participants refused eye donation and were assigned to non-donor group. Majority of the participants were siblings 170 (41.8%) of the deceased and the mean age of the deceased was 42.71 ± 17.56 years. The foremost concern before decision-making was transparency in how the cornea would be used (32.25%). The concern with regards to whether the body would remain intact after eye donation significantly decreased the probability of consent for eye donation. Conclusion The study highlights that barriers to eye donation in India are not cultural or religious but more due to misinformation and proper utilization of the donated tissue. This study also emphasizes the pivotal role of EDC's in facilitating the eye donation movement.

Abstract
We characterized the potential benefits and risks of participating in a microenterprise program targeting low-income women living with HIV (WLWH) in Alabama; and described potential mechanisms through which microenterprise programs could influence sexual risk behaviors and engagement in HIV care. Fourteen stakeholders and 46 WLWH (89% African American) participated in the qualitative study. Data were collected using in-depth interviews (stakeholders) and focus group discussions (WLWH). NVivo qualitative software was used for the management and analysis of the data. The data revealed four main mechanisms through which microenterprise programs could potentially improve health outcomes: (1) social support and encouragement from other women, (2) improvement in self-esteem, (3) creating structure in the women's lives, and (4) financial strengthening. Potential risks included unwanted disclosure of HV status, stigma and loss of insurance benefits. Microenterprise programs have the potential to be acceptable and may contribute to improved health and social outcomes among low-income WLWH in Alabama.

Abstract
In this work, the coagulation/flocculation/sedimentation treatment of dairy wastewater samples was investigated through serial factorial designs utilizing the saline extract obtained from Moringa oleifera (Moringa) as a coagulant. The sedimentation time (ST), pH, Moringa coagulant (MC) dose and concentration of CaCl2 have been evaluated through the response surface methodology in order to obtain the ideal turbidity removal (TR) conditions. The empirical quadratic model, in conjunction with the desirability function, demonstrated that it is possible to obtain TRs of 98.35% using a coagulant dose, concentration of CaCl2 and pH of 280 mg L-1, 0.8 mol L-1 and 9, respectively. The saline extract from Moringa presented its best efficiency at an alkaline pH, which influenced the reduction of the ST to a value of 25 min. It was verified that the increase in the solubility of the proteins in the Moringa stimulated the reduction of the coagulant content in the reaction medium, and it is related to the use of calcium chloride as an extracting agent of these proteins. The MC proved to be an excellent alternative for the dairy wastewater treatment, compared to the traditional coagulants.

Abstract
This study was conducted to investigate the antimicrobial activities of different solvent extracts of Moringa stenopetala (MS) leaves against nine selected pathogenic microorganisms. The disc diffusion method was used to assess antimicrobial activity and determine minimum inhibitory concentrations (MIC). Methanol, and chloroform extracts showed significant inhibitory activity against Klebsiella pneumoniae and Bacillus cereus. The greatest antimicrobial activity, determined by lowest MIC values (62.5 μg/mL), was observed for inhibition of C. albicans by the ethanol extract and Streptococcus pneumoniae by the methanol extract. The MICs of chloroform extract were 125 μg/mL against Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus, Listeria monocytogenes, and B. cereus. Water extract showed the lowest inhibition against these microorganisms, with MIC values of 250 μg/mL. The data presented in this study suggest that MS leaves have great potential in the development of food preservatives and antibiotic drugs.
