“…Likewise, the antioxidant capacity in the hydrophilic phase was superior to that obtained in the lipophilic phase (Table ). These results are similar to those previously reported by Usenik and others (), Ahmed and others (), and Solorzano‐Morán and others () where they demonstrated that the total antioxidant capacity of the epicarp was greater in comparison with the pulp for P. domestica L., L. siceraria , and S. purpurea fruits, respectively. In these studies, the antioxidant capacity of the hydrophilic and lipophilic phases was not determined separately.…”

Spondias purpurea L. is a fruit native to Mexico, however, it is found as far away as Brazil. It possesses a high commercial potential owing to its sensorial and nutritional qualities and its low cost of production. There exists a variety of ecotypes that have not been characterized and their adequate selection process, according to their strongest functional characteristics, will allow the establishment of improvement programs for this genetic resource. The object of this study was the chemical characterization and the determination of the in vitro and in vivo antioxidant capacity of 7 Spondias purpurea L. ecotypes. Differences were observed in the antioxidant capacity and the content of functional compounds among all the ecotypes analyzed. A high total phenolic content and a low flavonoid and carotenoid content were found, both in the epicarp and in the pulp. In each ecotype, the hydrophilic phase presented up to 40 times greater antioxidant capacity compared to the lipophilic phase. The hydrophilic phase of the epicarp of "Costeña Tierra Colorada" had the greatest antioxidant capacity and highest total phenolic content, whereas "Jocote" presented the lowest antioxidant capacity and total phenolic content. A positive correlation was observed between phenol levels and the antioxidant capacity in the epicarp. Regarding antioxidant activity in vivo, it was observed that in all analyzed concentrations of hydrophilic extracts of the epicarp of "Costeña Tierra Colorada" and in the highest "Jocote" concentrations, they provided thermo-protection against heat stress as well as a general well-being to the worm as evidenced by their high mobility.

“…The antioxidant activity in Mexican plum fruit was always higher in the epicarp than in the pulp. Similarly, Ahmed et al [42] reported a higher antioxidant activity in the epicarp than in the pulp of Lagenaria siceria fruits and they explained that the abundance of phenols in the epicarp was the reason of this difference. The ecotype with the highest content of antioxidant activity present on either epicarp or pulp was 'Conservera de Tlaxmalac' with 5.1 mM antioxidant capacity equivalent to concentration of ascorbic acid (ACECA) g −1 FW in the rind and 1.6 mM ACECA g −1 FW in the pulp.…”

Introduction. Mexico harbors a great diversity of Spondias purpurea ecotypes, whose fruit is called Mexican plum and has a good consumer acceptance because of its organoleptic and nutritional characteristics. Materials and methods. The concentrations of metabolites in 11 ecotypes of Mexican plum were determined from samples of rind (epicarp) and pulp originating from fresh seasonal fruit. Results and discussion. The mass of these fruits varied from 11.1 to 35.0 g, and the epicarp color ranged from purple and red, to orange and yellow. The content of total soluble solids, total sugars, and vitamin C was of 9.4−18.2 • Brix, 101.0−185.9 mg g −1 fresh weight (FW), and 0.6−2.1 mg g −1 FW, respectively. The total phenolic content was always higher in the epicarp (3.7 mg g −1 FW) than in the pulp (1.3 mg −1 FW), as was the total content of carotenoids and the levels of antioxidant activity. Additionally, positive correlations could be established between antioxidant activity and total phenolics, total phenolics and total carotenoids, and between the antioxidant activity in the epicarp and the total content of vitamin C. In addition, negative correlations were found between hue and the carotenoid content of the pulp, and between hue and the antioxidant activity in the epicarp and pulp. Conclusion. The results suggest that a higher content of phenols, carotenoids, and vitamin C, together with a purple or red coloration of the epicarp, can all be associated with an increase in the antioxidant activities of the epicarp and pulp of the Mexican plum.Keywords: Mexico / Latin America / Mexican plum / Spondias purpurea / antioxidant activity / carotenoids / phenolics / vitamin C / nutritional value Résumé -Attributs de qualité et composés fonctionnels des fruits de divers écotypes de prune mexicaine (Spondias purpurea L.). Introduction. Le Mexique abrite une grande diversité d'écotypes de Spondias purpurea dont le fruit est appelé prune mexicaine et possède une bonne image auprès des consommateurs en raison de ses caractéristiques organoleptiques et nutritionnelles. Matériel et méthodes. Les concentrations en métabolites de 11 écotypes de prune mexicaine ont été déterminées à partir d'échantillons de la peau (épicarpe) et de la pulpe de fruits frais de saison. Résultats et discussion. La masse de ces fruits s'est inscrite entre 11,1 et 35,0 g, et la couleur de l'épicarpe pouvait varier du rouge violacé à l'orange et au jaune. Le contenu en solides solubles totaux, en sucres totaux, et en vitamine C variait de 9,4 à 18,2 • Brix, de 101,0 à 185,9 mg g −1 poids frais (FW), et de 0,6 à 2,1 mg g −1 FW, respectivement. Le contenu phénolique était toujours plus élevé dans l'épicarpe (3,7 mg g −1 FW) que dans la pulpe (1,3 mg g −1 FW), tout comme la teneur en caroténoïdes totaux et les niveaux d'activité anti-oxydante. En outre, des corrélations positives ont pu être établies entre l'activité anti-oxydante et les composés phénoliques totaux, entre les composés phénoliques totaux et les caroténoïdes totaux, et entre l'activité anti-oxyda...

Moonmun, et al.: Antioxidant and Antibacterial Activity of Heliconia rostrataRhizomes of Heliconia rostrate, (family: Heliconiaceae) have been well known for antiophidic property. Ethnobotanically, rhizome of this plant has also been used to cure jaundice, intestinal pain and hypertension. This study aimed at evaluating the antioxidant and antimicrobial potency of two extracts of rhizomes of H. rostrata to find out the one, which exhibited better activity. Methanol and ethanol extract of the dried and defatted rhizomes were prepared and were subjected to qualitative and quantitative estimation of phytoconstituents, antioxidant assay and antibacterial evaluation. The methanol extract was found to give better yield than the ethanol extract. All phytoconstituents detected in the methanol extract were found in the ethanol extract also except for the glycoside content, which was found only in the methanol extract. Total phenolic and flavonoid content was higher in the ethanol extract compared to the methanol extract, whereas total tannin content was higher in the methanol extract. Both ethanol and methanol extracts exhibited antioxidant and antibacterial potency. The antioxidant activities of both extracts were found to be equal, while the ethanol extract exerted significantly higher antibacterial activity compared to the methanol extract. Key words: Heliconiaceae, rhizome, phytoconstituents, antioxidant, antimicrobialMedicinal plants offer alternative therapies with spectacular opportunities [1] . Heliconia rostrata, popularly known as false bird of paradise and hanging lobster claw (family: Heliconiaceae) is a shrub that is reported to contain calcium, nitrogen, potassium, magnesium, iron, phosphorous, chlorine, sulphur, sugar, carbohydrate, starch and protein [2] . This plant is reported to be well known for antiophidic property [3] . Ethnobotanically, the traditional people of Malaysia used these rhizomes to cure jaundice, intestinal pain and hypertension [4] . However, not much of experimental evidence was documented.Oxygen, the most important component for the survival of living being is highly reactive and can do serious damage to healthy cells of the body as a free radical. Oxidation produces free radicals, which can start chain reactions in the cell leading to cell damage and even cell death [5] . An antioxidant terminates these radical reactions by removing free radical intermediates, which causes ageing and disease like atherosclerosis, cancer, cardiovascular diseases and CNS disorders [6] thus, play a vital role in inhibiting or delaying the oxidation at the cellular level [7] . Synthetic antioxidants, butylatedhydoxytoluene (BHT), butylatedhydroxyanisole (BHA) and tert-butyl hydroquinone (TBHQ) are being evaluated in many countries for their potential health hazard and have been found to promote liver damage and causing cancer to laboratory animals [8] . In comparison, the plant sources prove to have less or no side effect [6] , thus channelizing the interest towards the nature for antioxidant potency.Re...
