RESUMENCaracterización del aceite de semilla de Moringa oleifera procedente de regiones de secano y de regadío del Punjab paquistaní.La intención del presente estudio ha sido la de investigar la composición del aceite obtenido de la semilla de M. oleifera cultivada en regiones de secano y de regadío Paquistaní. El , respectivamente. Estos resultados ponen de manifiesto que la procedencia de secano es el factor que más visiblemente influyen en el aumento del periodo de inducción y del contenido de C22:0 en los aceites, así como de la reducción del peso de la semilla, de la producción de aceite, del índice de yodo y del contenido en C18:1.

SUMMARY Characterization of Moringa oleifera Seed oil from Drought and Irrigated Regions of Punjab, PakistanThe aim of the present study was to investigate the composition of M.oleifera seed oil from drought and irrigated regions of Pakistan. The induction period (Rancimat 20L/h, 120 °C) of the M.oleifera oil from the drought region was significantly higher (9.63 h) as compared with those of irrigated regions (8.74, 8.33 h). Specific extinctions at 232 and 270 nm were 1.92 and 1.98, 1.68; 1.02 and 0.97, 0.75 respectively. The overall contents of tocopherols (α, γ and δ), which did not differ significantly in the Moringa oils from both regions ranged from 95. 85-103.80, 80.26-86.56 and 55.75-64.55 mg kg -1 respectively. Fatty acid profiles of the M.oleifera oils from drought and irrigated regions of Punjab consisted in a high level of oleic acid (up to 72.68 and 75.55, 74.66 %) followed by palmitic and behenic acid (up to 9.26 and 8.76, 9.20 and 5.46 and 3.72, 4.53 %) respectively. Results of various physical and chemical parameters of the investigated M.oleifera seed oils revealed that drought is one of the most visible factors that have amplified the induction period and C22:0 content of the oils and reduced seed weight, oil yield, iodine value and C18:1 content.

Studies on the Biolubricant Properties of Moringa Oleifera Seed Oil: Correlating Viscosity and Fatty Acid Composition

“…Oleic acid is the principal fatty acid in M.oleifera seed oil and this agrees with values (67.8 -85%) in the literature (Tsaknis et al, 1999;Abdulkarim et al, 2005;Anwar et al, 2006) . Fatty Acid (C ≥16) (%) 99.86 Table 4 shows the classification of the fatty acids in M. oleifera seed oil.…”

“…Extraction methods reported included mechanical press (Anwar et al, 2006;Eman & Muhamad, 2016), solvent extraction (Anwar & Bhanger, 2003;Abdulkarim et al 2005;Anwar et al, 2006) and enzymatic extraction (Abdulkarim et al 2005;Latif et al, 2011), the yield and physicochemical properties of the oil varied with method of extraction. M. oleifera seed oil has been reported to have high degree of unsaturation with oleic acid (67.8 -85%) as the most prominent fatty acid (Tsaknis et al, 1999;Abdulkarim et al 2005;Anwar et al, 2006;Nzikou et al, 2009). Studies on the viscosity of the oil as a function of temperature (Nzikou et al, 2009) and melting behavior (Mohammed et al, 2003;Abdulkarim et al 2005;Nzikou et al, 2009) of the oil have been reported.…”

Short-term Toxicological Evaluation of Monodora myristica Seed Oil

“…Oleic acid is very important in nervous cell construction; it has fundamental role in cardiovascular diseases prevention (Nasri et al 2005). The high percentage of oleic acid in the oil makes it desirable in terms of nutrition and high stability cooking and frying oil (Anwar et al 2006). A higher intake of oleic acid is associated with decreased risk of coronary heart disease caused by high cholesterol level in blood (Corbett 2003).…”

Applications of Natural Coagulants to Treat Wastewater − A Review

“…It is widely known that this plant can be utilized for beneficial purposes. Moringa is most often consuming as provisions and remedial resource limited to urban areas [19]. The most recommended coagulating agents with 12-14 kDa mass and about 10-11 isoelectric point (pI) are dimeric cationic proteins.…”
