“…The result also similar to its water leaves extract which expressed the highest TFC (5.20 mg CE/g extract) compared to calyx, peel, pulp and stem extracts [22]. Padmashree et al [30] reported that methanol-water (4:1) leaves extract of S. nigrum had the highest TFC (1.51 g/100 g) compared to methanol extract (1.01 g/100 g), ethyl acetate extract (0.65 g/100 g), and water extract (0.54 g/100 g). Study by Kandoliya et al [15] figured that methanolic pulp extract of sample GBL-1 showed the highest TFC (13.25 mg QE/100 g) among six varieties of eggplant.…”

Objectives: The goals of this research were to evaluate antioxidant potential from different organs of eggplant (Solanum melongena L.) using two antioxidant testing methods which were 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) and correlation of total phenolic and flavonoid content with their inhibitory concentration 50% (IC 50 ) of DPPH, and exhibitory concentration 50% (EC 50 ) of FRAP. Materials and Methods:Each sample was extracted by reflux using different polarity solvents. The extracts were evaporated using rotary evaporator. Antioxidant activities were tested using DPPH and FRAP assays, determination of total phenolic and flavonoid content were carried out by ultravioletvisible spectrophotometry and correlation with their IC 50 of DPPH and EC 50 of FRAP capacities were analyzed by Pearson's method. Results:The lowest IC 50 of DPPH scavenging activity 1.14 µg/ml and the lowest EC 50 of FRAP capacity 49.80 µg/ml was given by ethanolic leaves extract of eggplant. Ethanolic leaves extract of eggplant also presented the highest total phenolic content (TPC) (8.87 g gallic acid equivalent/100 g), while the highest total flavonoid content was shown by ethyl acetate leaves extract (24.50 g quercetin equivalent/100 g). There was a significantly negative correlation between TPC in leaves and fruit extracts of eggplant with their IC 50 of DPPH and EC 50 of FRAP. Conclusions:All different extracts of eggplant organs (except n-hexane stem extract) were categorized as a very strong antioxidant by DPPH method. Phenolic compounds in eggplant leaves and fruit extracts were the major contributor in antioxidant activities by DPPH and FRAP methods. DPPH and FRAP showed linear results in antioxidant activities of eggplant leaves, fruit and stem extracts.

Solanum nigrum was subjected to five fertiliser treatments on the field and glasshouse to determine the wild vegetable's nutritional response to fertilisers with maturity and best fertiliser option for optimum harvesting period of the leaves for nutritional benefits. The application of 50 kg N/ha + 4.07 t manure/ha fertiliser increased protein uptake on the field and glasshouse; vitamin C in the glasshouse and lipid on the field. The addition of 100 kg N/ha + 8.13 t manure/ha increased the uptake of vitamin C on the field and lipid content in the glasshouse. The control increased the accumulation of fibre on both the field and glasshouse while also lowering the phytate content in the glasshouse. Fibre was at peak 11 and 4 weeks after transplanting on the field and glasshouse respectively while lipids were highest 11 and 6 weeks after transplanting.Vitamin C was highest 9 and 6 weeks after transplanting on the field and glasshouse respectively after which it sharply declined towards senescence. Protein was at peak between the 3 rd and 4 th weeks after transplanting. Although various nutrients responded differently to fertiliser treatments, these results indicate the potential of S. nigrum to meet the human nutritional recommended daily adequate intake values. Also, the results of this study indicate that the cultivation of this wild vegetable increases its nutritional composition as compared to the wild Downloaded by [Temple University Libraries] at 21:30 14 June 2016A c c e p t e d M a n u s c r i p t 124 species. The best fertiliser option and best time to harvest the plant is best advised according to specific nutritional challenges. The consumption of S. nigrum could be expected to contribute a large proportion of the nutritional requirements in the human body.

“…También se calcularon los valores de Q10 para la degradación térmica de la actividad antioxidante del extracto de B. orellana L. a las condiciones de almacenamiento. En la tabla 3 se aprecia que el valor de este parámetro al igual que los anteriores parámetros térmicos tiene la misma tendencia y valores similares que para los compuestos fenólicos, lo cual ratifica que las propiedades antioxidantes de los extractos de B. orellana L. se deben a los compuestos fenólicos (Padmashree et al, 2014).…”

“…Se han llevado a cabo estudios orientados a establecer la estabilidad térmica de compuestos fenólicos como es el caso de antocianinas en zanahoria negra (Kırca et al, 2007), en hojas de Solanum nigrum L. (Padmashree et al, 2014); papas, zanahorias y uvas (Reyes y Cisneros-Zevallos, 2007;He et al, 2015). Sin embargo, el efecto que ejerce la temperatura sobre los compuestos fenólicos depende de la matriz de la cual se hayan extraído dichos compuestos (Padmashree et al, 2014) y tampoco se encuentran estudios que evalúen el efecto de la temperatura o el pH, sobre la estabilidad de la actividad antioxidante de dichos compuestos. El objetivo del presente trabajo fue evaluar el efecto que tiene la temperatura (T), los sólidos solubles (SS) y el pH, sobre la velocidad de degradación de los compuestos fenólicos extraídos de semillas de B. orellana L. y sobre velocidad de pérdida de actividad antioxidante, tanto en temperaturas típicas de procesos de alimentos (70, 80 y 90 °C), como en temperaturas de almacenamiento (-20, 8, 23 y 37 °C).…”

El objetivo del presente trabajo fue evaluar el efecto de la temperatura, el pH y el contenido en sólidos solubles, sobre la velocidad de reacción, en la degradación térmica de los fenoles totales del extracto etanólico de semillas de Bixa orellana L. Se determina también la estabilidad de fenoles totales y su actividad antioxidante durante 91 días a condiciones de almacenamiento de-20, 8, 23 y 37 °C. Los resultados mostraron que la degradación de fenoles totales, se ve afectada por la temperatura y los sólidos solubles, siguiendo una cinética de primer orden, tanto en condiciones de procesamiento como de almacenamiento. Por su parte, la actividad antioxidante (ABTS y FRAP), se ve afectada por la temperatura de almacenamiento. Los tiempos de vida media estuvieron entre 27.74-38.25; 27.99-36.51 y 22.18-35.98 días-1 , para compuestos fenólicos, ABTS y FRAP, respectivamente. Mientras que la energía de activación fue 4.08, 3.24 y 5.52 KJ.mol-1 para fenoles totales, ABTS y FRAP, respectivamente. Se concluye que la actividad antioxidante de estos extractos depende de su contenido de compuestos fenólicos los cuales son afectados por la temperatura y por el contenido de sólidos solubles.
