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

This study characterizes the allelopathic effect in the germination of Allium cepa seeds, and toxic on the species Artemia salina, of aqueous extracts of leaves of Aspidosperma pyrifolium and Combretum leprosum and the constituent phytochemical compositions. For this, Allium cepa seeds were germinated in systems containing aqueous extracts (200, 400 and 800 mg.L-1) and distilled water, to evaluate aspects of germination, mitotic phases, mitotic index and limit value of cytotoxicity. The toxicity of the aqueous extracts was evaluated in Artemia salina. The extracts were evaluated qualitatively and quantitatively when the substances present to define the phytochemical profile. The aqueous extract of A. pyrifolium negatively affects the germination process in the hypocotyl and seedling growth at 800 mg.L-1. The LC50 found for the aqueous extract of A. pyrifolium was 4986 mg.L-1. The effect of C. leprosum extract on germination resulted in an increase in the dry matter of the root at 400 mg.L-1 and in the density of the dry matter of the root at 800 mg.L-1. In addition, it reduces the seedling matter at 200 mg.L-1, corresponding to the trend observed in the mitotic index, in which this concentration presented a sublethal score for the limit value of cytotoxicity. The maximum concentration evaluated was not sufficient to determine an LC50 in A. salina. The phytochemical profiles of both species demonstrated classes of substances with potential pharmacological application. This information is important because these species are commonly used as food for farm animals and for purposes in folk medicine.

In this study we evaluated the action of crude aqueous extracts obtained from rhytidome of Hymenaea stigonocarpa (jatobá-do-cerrado) on Allium cepa meristematic root cells in three concentrations: 0.082, 0.164, 0.328g/mL, at exposure times of 24 and 48 h. The slides were prepared by the crushing technique, and cells analyzed throughout the cell cycle, totaling 5000 for each control group and concentration. It was found that all three concentrations, including the lowest which is considered ideal for use, in all exposure times, had significant antiproliferative action on the cell cycle of this test system. For cells under division, we observed a high number of cells in prophase. Therefore, under the conditions studied H. stigonocarpa indicated to be cytotoxic.

AbstractPlantago is the most important genus of Plantaginaceae family and is used in traditional medicine around the world for different purposes. Plantago coronopus L., Plantago major L., Plantago media L. and Plantago lanceolata L. are most commonly used species of Plantago in traditional medicine in Turkey. The main goal of this study was to investigate the eventual anti-mitotic and anti-genotoxic effects of P. lanceolata L. leaf aqueous extracts (15 g/L and 30 g/L) on Allium cepa L. root tip meristem cells which were treated with 0.7% hydrogen peroxide. For this purpose, two different experiments were performed under the same conditions. In the first experiment, Allium cepa onion bulbs were treated with 0.7% H2O2 for 1 h. After the H2O2 treatment, the onion bulbs were treated with two different concentrations (15 g/L and 30 g/L) of P. lanceolata extracts for 24 h. In the second experiment, A. cepa onion bulbs were treated with two different extract concentrations (15 g/L and 30 g/L) for 24 h and then with 0.7% H2O2 for 1 h. The test concentrations were determined according to doses which are recommended in alternative medicinal usage by people. As positive and negative control 0.7% H2O2 and tap water was used, respectively. As a result, it was determined that aqueous extracts reduced mitotic index and chromosome aberrations in treatment groups in comparison with controls. These results showed that P. lanceolata aqueous extracts have anti-mitotic and anti-genotoxic effects.
