Antioxidant And Antimicrobial Activities

The radish (Raphanus sativus L.) is a vegetable of the Brassicaceae family cultivated worldwide and has several medicinal properties. Its biological activities are related to various secondary metabolites present in the species, especially phenolics. Thus, the objectives of this study were the chemical analysis and evaluation of the antioxidant and antimicrobial activities of the dry extract and fractions of the fodder turnip leaves (R. sativus var. oleiferus Metzg.). Samples were analyzed by mass spectrometry and the antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical method and the reducing power method. Antimicrobial activity was determined by the agar diffusion and microdilution methods. The total phenols were concentrated in the butanol fraction (121.27 mg GAE/g) and the flavonoids were concentrated in the ethyl acetate fraction (98.02 mg EQ/g). The ethyl acetate fraction showed the best antioxidants results, with 83.45% of free radical scavenging and 11.34% of ferric ions reduction. The analysis of antimicrobial activity showed that the dry extract had the highest average zone of inhibition against Bacillus subtilis (18.67 mm). Smaller values of the minimum inhibitory concentration for Micrococcus luteus were, and the ethyl acetate fraction showed a lower minimum inhibitory concentration (0.1 mg/ml) for that microorganism. There was a strong correlation between the antioxidant activity and the content of phenols and flavonoids. The results showed the potential antioxidant and antimicrobial activities of this extract with the ethyl acetate fraction being most promising for further studies.

Background: Allium cepa, Allium sativum, and Monodora myristica are commonly sourced food condiments in every household in Nigeria. In the present study, we investigated the phytochemical compositions, in vitro and in vivo antioxidant activity of these plants. Methods: The aqueous extracts from the A. cepa, A. sativum, and M. myristica were evaluated for phytochemical composition using standard protocols while the antioxidant activities were evaluated using the reducing power assay. Forty-five (45) Male Wistar rats (weighing 185±10 g) were divided into five groups (n=9) and were orally administered with 100 mg/kg BW each of A. sativum, M. myristica, A. cepa, and ascorbic acid while the control group received 0.5 mL/kg BW distilled water alone. Animals (n=3) from each group were sacrificed after the 20th, 25th, and 30th days of oral administration. The blood and tissue samples were collected for the analysis of biochemical parameters. Result: Our results revealed the presence of flavonoids, alkaloids, tannins, saponins, and terpenes in the plant extracts. A. sativum had the highest reducing power capacity followed by M. myristica and then A. cepa. The in vitro antioxidants activities demonstrated by the plant extracts were higher than that of ascorbic acid but less than butylated hydroxytoluene. In vivo antioxidant studies showed a marked increase (p<0.05) in the level of catalase with a concurrent decrease (p<0.05) in the levels of MDA and H2O2 in the liver and kidney of rats administered with aqueous extracts of the condiments compared to the normal control and ascorbic acid in the following order control < ascorbic acid < A. cepa < M. myristica < A. sativum. Conclusion: Based on these findings, we infer that the aqueous extracts of A. cepa, A. sativum, and M. myristica are rich in antioxidants and as a result could serve as promising novel functional foods and nutraceuticals

El objetivo de este trabajo fue estudiar la acción de extractos acuosos de ajo (Allium sativum L, Liliaceae), palta (Persea americana Mill, Lauraceae) y ruda (Ruta graveolens L, Rutaceae) sobre el desarrollo de la hortaliza rabanito (Raphanus sativus L, Brassicaceae). Los extractos se prepararon a partir de bulbos de A. sativum, semilla de P. americana y hojas y flores de R. graveolens a los cuales triturados se le adiciona agua hervida. Los tratamientos fueron extractos puros al (20% p/v). El diseño fue completamente aleatorizado con 4 repeticiones. Se determino peso fresco (g), peso seco (g), longitud de raíz (cm), longitud área (cm) y área foliar(cm2). Los datos se analizaron mediante ANOVA y Test de Tukey para la comparación de medias. Los resultados alcanzados muestran de que no existe efectos significativos en comparación con el control, del potencial alelopático de los extractos acuosos evaluados bajo condiciones controladas. Palabras claves: Extractos acuosos, semillas, hojas, flores, bulbos, Allium sativum, Persea americana, Ruta graveolens. ABSTRACT The use of plants with allelopathic activity nowadays is very important because it allows us to develop a profitable agriculture and non-polluting the environment. The objective of this work was to study the action of aqueous extracts of garlic (Allium sativum L, Liliaceae), avocado (Persea americana Mill, Lauraceae) and rough (Ruta graveolens L, Rutaceae) on the development of vegetable radish (Raphanus sativus L, Brassicaceae). The extracts were prepared from A. sativum bulbs, P. americana seeds and R. graveolens leaves and flowers to which he adds crushed boiled water. Treatments were the pure extracts (20% w / v). The design was completely randomized with 4 repetitions. It was found fresh weight (g), dry weight (g), root length (cm) long area (cm) and leaf area (cm2 ). The data was analyzed with Anova and Tukey test for the comparison of averages. The results show that there is no significant effects compared to the control of allelopathic potential of aqueous extracts tested under controlled conditions. Keywords: Aqueous extracts, seed, leaves, flowers, bulbs, Allium sativum, Persea americana, Ruta graveolens.
