“…reported by Gupta et al (1989) and Makkar and Becker (1997). On the other hand, the leaves samples of MPH and MC had lower total phenol content and condensed tannins than tree leaves at 100 and 250 cm; which shows that under controlled conditions can be generated lots of leaves with better quality from the point of view of health.…”

“…The levels of total phenols reported in this study are similar to those reported by Gupta et al (1989); while the relatively low tannin content reported here is consistent with that siembra, los ecotipos analizados y el manejo poscosecha. Nutricionalmente hablando, el requerimiento mínimo recomendado de vitamina C para un adulto es de 60 mg (Padh, 1994); por lo tanto, 100 g de hoja proveniente de los árboles de 25, 100 y 250 cm pueden contribuir con el 107, 91.7 y 74%, respectivamente, del requerimiento diario de esta vitamina.…”

ResumenRecientemente la moringa se ha introdujo en Guanajuato; sin embargo, los arboles no crecen en forma uniforme, hay diferencias de hasta 225 cm. El objetivo fue evaluar la calidad nutrimental y nutracéutica de la hoja de árboles de diferente tamaño. Las hojas se cosecharon en abril de 2013 en la huerta recién introducida por el INIFAP en Celaya, Guanajuato. Se determinó la calidad nutrimental por su composición química y contenido de calcio y hierro y la calidad funcional por el contenido de vitamina C, compuestos fenólicos y capacidad antioxidante. El contenido de proteína de las hojas de los árboles de 100 cm fue mayor (24.7%) que el de los árboles de 25 (21.1%) y 250 cm (22.3%), y menor al de la muestra comercial de Oaxaca (29.3%). Cien gramos de hoja de los árboles de 25, 100 y 250 cm pueden contribuir con el 107, 91.7 y 74%, del requerimiento diario de vitamina C. La hoja de la moringa de los arboles es mejor fuente de calcio y hierro, vitamina C, fenoles, taninos que las muestras comerciales. Lo mismo se aplica para la capacidad antioxidante. La hoja de la moringa presenta mejores propiedades nutracéuticas que el perejil, orégano, tomillo y epazote. Estos resultados demuestran la falta de uniformidad al preparar las mezclas comerciales y que el manejo apropiado puede lograr mejorar la calidad AbstractMoringa has been recently introduced in Guanajuato; however, the trees do not grow evenly, there are differences of up to 225 cm. The objective was to evaluate the nutritional and nutraceutical quality of leaf from trees of different sizes. The leaves were harvested in April 2013 in the newly-introduced garden by INIFAP in Celaya, Guanajuato. Nutritional quality for its chemical composition and content of calcium and iron and functional quality for vitamin C content, phenolic compounds and antioxidant capacity were determined. The protein content of the leaves from trees of 100 cm was higher (24.7%) than trees of 25 (21.1%) and 250 cm (22.3%), and lower than the commercial sample from Oaxaca (29.3%). One hundred grams of leaf from trees of 25, 100 and 250 cm can contribute with 107, 91.7 and 74% of the daily requirement of vitamin C. Moringa leaf of the tree is a better source of calcium and iron, vitamin C, phenols, tannins than the commercial samples. The same applies for antioxidant capacity. Moringa leaf has better nutraceutical properties than parsley, oregano, thyme and epazote. These results show the lack of uniformity in preparing commercial mixtures and appropriate management can achieve better quality of moringa leaf for commercial purposes. This is the first report on the quality of leaf from Mexican materials of moringa. de la hoja de moringa para propósitos comerciales. Este es el primer reporte de la calidad de la hoja de materiales mexicanos de moringa.Palabras clave: antioxidante, calidad de la hoja, compuestos fenólicos, moringa, nutrimental.

Studies of chemical and enzymatic characteristics of Yacon (Smallanthus sonchifolius) and its flours

et al. 2013

Due to the importance of studies on yacon related to health, its in natura pulp, in natura peel, pulp flour, and peel flour were chemically analyzed in terms of its centesimal composition, specific minerals, total dietary fiber and fractions, pH, total soluble solids, total titratable acidity, tannins, oxalic acid, and nitrate. The polyphenoloxidase and peroxidase enzymatic activities were evaluated for in natura pulp and peel only. Yacon pulp and peel flour presented average yield of 7.94% and 10.86%, respectively. The in natura pulp presented a higher moisture and carboydrate content and lower lipid, protein, total dietary fiber, and ash than those of the peel flour. The same pattern was observed for pulp flour when compared to peel flour. The highest tannin, nitrate, and oxalic acid levels were found in the peel flour, 15,304.5 mg.kg-1, 1,578.3 mg.kg-1, and 7,925.0 mg.kg-1 (wet weight), respectively. The polyphenoloxidase and peroxidase enzymes presented higher enzymatic activity in the yacon peel. Based on the results obtained, it can be said that the yacon and its derivatives are important dietary carbohydrate and mineral sources and contain antinutritional substance contents lower than those harmful to health.

“…Moringa leaves are an abundant source of polyphenols [16], flavonoids [17], minerals [18], alkaloids and proteins [19,20]. The substances such as bioactive carotenoids, tocopherols and vitamin C showed health-promoting potential in maintaining a balanced diet and protecting against free-radical damage that might initiate many diseases [21].…”

Background: Health benefits of designed functional foods using dairy fermented products in co-production with medicinal herbs are under comprehensive investigations. Yoghurt has triggered a functional food revolution while green tea and Moringa oleifera represent precious source of high content of various types of antioxidants and micronutrients. Oxidative stress and lipid peroxidation are suggested mechanisms involved in lead toxicity. The aim of present study was to assess protective effects of green tea and moringa leave extracts and their bio-yoghurts against lead acetate-induced oxidative stress in male rats by following liver weight and enzymes and lipids profile.
