Abstract Background Rumex abyssinicus (RA) is one of indigenous plants to Ethiopia having traditional values during butter refinement in rural areas. This paper presents a comparative study of the antioxidant and antibacterial activities of RA sample extract to that of Zingiber officinale (ZO) and Curcuma longa (CL). Methods Phytochemical screening tests were, first, done using different confirmatory tests prior to quantitative determinations. Quantitative determinations were then conducted—the total phenolic content by the Prussian blue method, total flavonoid content by the aluminum colorimetric assay, and antioxidant activity by the reducing power assay and the cyclic voltammetry technique. Results All of the samples showed positive tests, with different intensities, for the presence of phenolics, flavonoids, glycosides and tannins, but not for alkaloids. The total phenolic content, the total flavonoid content and the antioxidant activities of RA (in mg/100 g dry weight) were found to be 319.208 ± 15.997, 113.252 ± 1.702 and 45.632 ± 2.026, respectively. On the other hand, both oxidation and reduction peaks were observed in the cyclic voltammetry analysis of the herbs, showing a quasi-reversible redox process of their phenolic compounds. The determination of the inhibition zones (in mm) of ethanol extract of RA was found to be 20.33 ± 0.58, 21.67 ± 0.58, 19.17 ± 0.29, 18.17 ± 0.29, and 21.67 ± 0.58 against Staphylococcus aureus, MRSA, Streptococcus pneumonia, Escherichia coli, and Shigella flexneri bacteria strains, respectively. Conclusion The substantial antioxidant and antibacterial activities of RA compared to ZO and CL indicate that the traditional use of the herb to refine butter and keep it safe longer without rancidity formation and other traditional medicinal practices can be attributed to both its antioxidant and antibacterial activities.

Proximate And Mineral Composition

A study was conducted on the proximate and mineral composition of native and hybrid pangas, namely Pangasius pangasius and Pangasius hypophthalmus at raw and fried stages between January and December 2017. At the raw stage higher amount of average protein (23%) found in native pangas compared to hybrid (19.7%) and hybrid pangas contain higher fat (15.95%) compared to native (12.75%), although the moisture content was the same in both. Protein and fat were higher in both fishes at 26.8% and 20.95% in natives and 24.05% and 24.2% in hybrids at the fried stage. At the raw stage, mineral contents were higher in natives and the highest content was sodium (185.38 mg/100 g) followed by phosphorus (166.90 mg/100 g) and calcium (116.35 mg/100 g) and slightly decreased those minerals at the fried stage of the same fish. In the fried stage, mineral contents were found almost the same, although calcium, magnesium, iron was slightly varied and phosphorus, sodium found high in amount. But energy level was higher (328 Kcal) in hybrids compare to native. Thus, the study of raw and fried stages indicates that native pangas are better in proximate and mineral composition than the hybrids, but the energy was high in hybrids. J. Asiat. Soc.

Field pea seeds from 10 cultivars grown at two locations in Manitoba in 1986 and 1987 were analyzed for proximate and mineral profiles. Cultivars differed significantly in their level of total protein, crude fat, ADF, and all minerals tested. However, differences were not extremely large and were comparable to European reports. Location-year also had a significant effect on the levels of total protein, ADF, and all minerals tested. In most cases, the warmest location-year produced relatively higher levels of minerals, ash, and total protein, and lower seed yield than the coolest location-year.

Los aceites esenciales son compuestos orgánicos importantes en el sector farmacéutico debido a sus propiedades antimicrobianas, volviéndose una alternativa de solución para determinadas fitopatologías. En el presente estudio se evaluó in vitro la actividad inhibitoria de aceites esenciales de Curcuma longa y Zingiber officinale contra Colletotrichum sp. obtenidas a partir de cultivos de Dioscorea rotundata en Toluviejo (Sucre, Colombia). Concentraciones de 3,000; 5,000; 8,000 y 10,000 mg/L de extracciones de aceite (método de hidrodestilación asistida por microondas) fueron aplicados a cultivos in vitro del hongo. Además, se empleó un testigo absoluto y controles positivo y negativo. Los aceites fueron caracterizados por cromatografía de gases acoplado a espectrometría de masa. La actividad inhibitoria se realizó por medio de la prueba de siembra en superficie (porcentaje de índice de inhibición). Los mayores valores de índice antifúngico se observaron a 10,000 mg/L similar al obtenido con el control positivo por benomil. De la caracterización química de los aceites esenciales el metabolito secundario que se presentó con mayor rango fue el monoterpeno 3-Thujeno y el citral. Los aceites esenciales de C. longa y Z. officinale generaron actividad inhibitoria contra el crecimiento de Colletotrichum sp., y por lo tanto pueden ser empleados para reducir la antracnosis.
