oxidation of low-density lipoprotein (ldl) has been strongly suggested as a key factor in the pathogenesis of atherosclerosis. thus, the inclusion of some anti-oxidant compounds in daily dietary food stuff may inhibit the production of oxidized ldl and may decrease both the development and the progression of atherosclerosis. the present work investigated the inhibitory effects of extract of all...

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...

Species from the genus Campomanesia have been studied due to their biological activity and low toxicity. However, studies on fruit peel of these species are scarce. In this context, effects ethanol extract sessiliflora (O. Berg) Mattos (CS) guazumifolia (Cambess) O. Berg (CG) were evaluated concerning effect germination meristem cells roots Allium cepa. The CG ethanolic showed flavonoid compoun...

Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze...

Oxidation of low-density lipoprotein (LDL) has been strongly suggested as a key factor in the pathogenesis of atherosclerosis. Thus, the inclusion of some anti-oxidant compounds in daily dietary food stuff may inhibit the production of oxidized LDL and may decrease both the development and the progression of atherosclerosis. The present work investigated the inhibitory effects of extract of Al...

Dietary onion and garlic caused an increase in the level of plasma triglyceride which could be due to insulin like activity of dietary alliums and other factors that promote lipogenesisi in growing stages. Changes in the plasma triglyceride level in the control group due to change in age and sex were also noted. The triglyceride level was more in female birds when compared to males of similar a...

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...

Allium cepa, Guard Cell Protoplasts, Malate, Vicia faba Isolated and purified guard cell protoplasts of starch-containing ( Vicia faba) and starch-lacking (Allium cepa) stomata were used to study the metabolism of malate and Clanions as correlated with the K +-induced swelling of protoplasts. The correlation between swelling and malate synthesis in starch-containing and the inhibition of this c...

A comparative study of the lectins from the families Amaryllidaceae and Alliaceae reveals many common features: all bind D-mannose exclusively and have similar molecular structures and amino acid compositions. All these lectins contain subunits of M, 11500-14000 which are not linked by disulphide bonds and occur as dimers (in Allium sativum, A. vineale, A. ursinum, A. moly, Narcissus pseudonarc...
