We have purified a novel alliinase (EC 4.4.1.4) from roots of onion (Allium cepa L.). Two isoforms with alliinase activity (I and II) were separated by concanavalin A-Sepharose and had molecular masses of 52.7 (I) and 50.5 (II) kD on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and 51 (I) and 57.5 (II) kD by gel filtration fast-protein liquid chromatography. Isoform I had an isoel...

To screen the wound healing activity of different extracts of Allium cepa L. in excision, incision and dead space wound models in albino rats. The tubers of Allium cepa L. (Family Liliaceae) were exhaustively defatted with petroleum ether (40-60C) and the marc was subjected to continuous extraction with solvent ether, chloroform, alcohol and chloroform water I.P. All the extracts were tested fo...

Hospital effluents are serious problems in developing countries like Brazil, and when not treated adequately, can cause mutagenic effects on live organisms. Biomonitors, like Allium cepa L., which is one of the most used plant species when monitoring effluent genotoxicity, have been used to alert the world population about environmental contamination and genotoxic chemical emissions. The Allium...

OBJECTIVE Diabetes mellitus (DM) is associated with significant morbidity and mortality and its prevalence is increasing worldwide. Although conventional antidiabetic agents are known to ameliorate the symptoms of diabetes, they also may cause adverse effects. The purpose of this review was to organize and discuss various studies that have been previously conducted indicating the efficacy of Al...

The term 'shallot' in Croatia denotes three genetically and morphologically different, vegetatively reproduced relatives of the common onion, Allium cepa L., which are mainly traditionally cultivated for consumption and as a spice: A. cepa Aggregatum group, (2n = 2x = 16), A. × proliferum (Moench) Schrad. (2n = 2x = 16) and A. × cornutum Clementi ex Vis. (2n = 3x = 24). This paper reviews the r...

N-nitroso compounds, such as N-nitrosodiethylamine (NDEA), can be formed by the reaction of secondary amines with nitrosating agents, and are suspected to be involved in tumors in humans. NDEA has been considered a weak carcinogen in genotoxic assays probably due to the inefficient nitrosamine activation system that is used and/or to the efficient repair system. In this work, we evaluated the s...

Allium cepa L. is known to possess numerous pharmacological properties. Our aim was to examine the in vitro effects of Allium cepa L. extract (AcE) on Porphyromonas gingivalis LPS and Escherichia coli LPS-stimulated osteoclast precursor cells to determine cell viability to other future cell-based assays. Osteoclast precursor cells (RAW 264.7) were stimulated by Pg LPS (1 μg/mL) and E. coli LPS ...

The antisickling effects of the extracts of three vegetables highly consumed in Nigeria were investigated which included: Allium cepa (Onion), Allium sativum (Garlic) and Telferia occidentalis (Ugu). The extracts were partitioned into, the fat-soluble (FAS), the water-soluble (WAS), the butanol-soluble (BUS) and the crude aqueous extracts (CAEs) respectively. Free amino acid concentrations of t...

N -nitroso compounds, such as N -nitrosodiethylamine (NDEA), can be formed by the reaction of secundary amines with nitrosating agents, and are suspected to be involved in tumors in humans. NDEA has been considered a weak carcinogen in genotoxic assays probably due to the inefficient nitrosamine activation system that is used and/or to the efficient repair system.
