“…They can increase the protection of the body against diseases such as cancer and they are in the class of antitumor compounds in medical science. The mechanism for enhancing the body protection by anthocyanins lies in the fact that they scavenge free radicals in the body and contribute to reduce the oxidative stress (Silva et al 2007). …”

Abstract. Kuspradini H, Rosiarto AM, Putri AS, Kusuma IW. 2016. Antioxidant and toxicity properties of anthocyanin extracted from red flower of four tropical shrubs. Nusantara . Some of flowers are colored by anthocyanins and make their own shade profile. Anthocyanins are natural colorants which have gained a growing interest due to their extensive range of colors and beneficial health effects. Anthocyanin content, antioxidant and toxicity activity of four red flowers (Bougainvillea glabra, Jatropha integerrima, Melastoma malabathricum and Mussaenda philippica) has been evaluated in this study by pH-differential, DPPH and Brine Shrimp Lethality method, respectively. In this present work, 1% HCl-ethanol and ethanol solvent were used for the extraction. The extractive yield was varied in different extraction system, 5.80 to 13.30% in 1% HCl-ethanol and 6.29 to 8.81% in ethanol solvent. The IC 50 of antioxidant from different extraction systems were also varied, whereas the acidified ethanol extracts showed a highest scavenging activity than the ethanol extracts, 11.67 to 46.38 ppm and 79.08 to 133.35 ppm, respectively. The free radical scavenging action of 1% HCl-ethanol extracts of flower are in the order as J. integerrima > M. malabathricum > M. philippica > B. glabra while in the ethanol extracts are in the order as M. malabathricum > J. integerrima > B. glabra >M. philippica. In the group of 1% HCl-ethanol extracts, Jatropha integerrima Jacq was the richest in anthocyanin content (15.83 mg CGE/100 g DW) and showed the strongest antioxidant activity (11.67 ppm) and not toxic. Therefore, these can be regarded as a potential pigment source for food and natural product applications.

“…Numerosos estudios se han realizado para la identificación y caracterización de diferentes compuestos antioxidantes debido a la importancia de estos en la prevención de enfermedades cardiovasculares, inflamatorias y neurológicas; así como también enfermedades cancerígenas y el retardo del envejecimiento (Bravo, 1998;Lichtenthäler & Marx, 2005;Silva, Pompeu, Larondelle, & Rogez, 2007).…”

“…En este tipo de alimentos, los compuestos antioxidantes más abundantes son por lo general los polifenoles (Bravo, 1998). Para la purificación de estos compuestos a nivel de laboratorio, se han probado principalmente: cromatografía de fase reversa con Sephadex (Mazza & Velioglu, 1992) o cromatografía iónica (Gil, Tomás-Berberán, Hess-Pierce, Holcroft, & Kader, 2000) y resinas absorbentes, que han sido ampliamente utilizadas para aislamiento, purificación, recuperación y concentración de antocianinas (Chandra, Nair, & Iezzoni, 1993;Liu, Xiao, Chen, Xu, & Wu, 2004;Liu et al, 2007;Scordino, Di Mauro, Passerini, & Maccarone, 2004;Silva, Pompeu, Larondelle, & Rogez, 2007). Sin embargo, no se encontró ningún estudio para la separación de polifenoles utilizando tecnología de membranas.…”

El fraccionamiento de los polifenoles de los jugos del mesocarpio, placenta y cáscara de tomate de árbol morado utilizando el tamaño de poro de la membrana como medio de selección, se realizó utilizando micro y ultrafiltración tangencial; pruebas realizadas con HPLC demostraron que no se realizó el fraccionamiento de los compuestos fenólicos. Los procesos de concentración de los jugos clarificados de placenta y cáscara de tomate de árbol por Osmosis Inversa obtuvieron un factor de concentración volumétrica de 2 y 2,2 respectivamente. La concentración de polifenoles se incrementó en 1,5 veces para placenta y 2,4 veces para la cáscara y la capacidad antioxidante para los dos jugos aumento en 2,4 veces. Las antocianinas de la placenta se incrementaron en 2,6 veces. La utilización de la resina XA 5071 FG concentró los compuestos fenólicos con el aumento de la capacidad antioxidante en un rango entre 4 y 5,5 y la concentración de antocianinas aumentó en 1,8 veces en el jugo de placenta. En conclusión el proceso de concentración de polifenoles del tomate de árbol fue más eficiente utilizando la resina XA 5071 FG que en el proceso de osmosis inversa utilizado en este estudio.

“…5 Em trabalhos anteriores foram realizadas otimizações da extração sólido-líquido de compostos fenólicos a partir de suas folhas 6 e da adsorção desses compostos sobre diferentes resinas macroporosas a partir de extratos brutos. 7 Adicionalmente, a extração em fase sólida utilizando-se cartuchos com adsorventes em fase reversa (SPE-C18) é um método muito utilizado para a purificação de extratos fenólicos. 8,9 Por exemplo, flavonoides de folhas de I. edulis foram purificados por esse método a partir de soluções metanólicas; 4 e procianidinas de licor de cacau foram purificadas a partir de solução acetônica.…”

Recebido em 31/10/08; aceito em 2/7/09; publicado na web em 8/12/09 PURIFICATION OF PHENOLIC COMPOUNDS FROM Inga edulis LEAVES USING SOLID-PHASE EXTRACTION: MAJOR COMPOUNDS QUANTIFICATION AND ANTIOXIDANT CAPACITY EVALUATION. A phenolic fraction was obtained from of the acetone-water-acetic acid extract of Inga edulis leaves, by liquid-liquid partition and SPE-C 18 cartridges. This method provided an increase of 108, 66, 51, 50 and 36% of flavonols, proanthocyanidins, total polyphenols, gallotannins and flavanols, respectively. The major phenolics in purified fraction were procyanidin B2, catechin and myricetin-3-O-a-L-rhamnopyranoside, which achieved increases of 111, 47 and 45%, respectively, after SPE. Acid hydrolysis confirmed the presence of procyanidins, prodelphinidins and glycosylated flavonoids.
