| exploring allium species as a source of potential medicinal agents. | it has been shown that allium species may help to prevent tumor promotion, cardiovascular diseases and aging; all processes that are associated with free radicals. therefore the allium species of both cultivated species (allium nutans l., allium fistulosum l., allium vineale l., allium psekemense b. fedtsch, allium cepa l., allium sativum l.) and wild species (allium flavum l., allium sphaerocephalum l., allium atroviolaceum boiss, allium schenoprasum l., allium vineale l., allium ursinum l., al ... | 2006 | 16676298 |
| comparative study of antioxidant properties of wild growing and cultivated allium species. | allium species are cultivated for the edible bulb, which is used mainly as flavoring in foods. besides that, they could prevent tumor promotion and some processes that are associated with free radicals, such as cardiovascular diseases and aging. therefore, different allium species, both cultivated (allium nutans l., a. fistulosum l., a. vineale l., a. pskemense b. fedtsch, a. schoenoprasum l., a. cepa l. and a. sativum l.) and wild (a. flavum l., a. sphaerocephalum l., a. atroviolaceum boiss, a. ... | 2008 | 17726730 |
| [deltosides from allium nutans l]. | steroid glicoside which structure was elucidated by using mass-spectroscopic and nmr techniques, has been isolated using column chromatography on reverse-phase silicagel (c-18) from underground parts of allium nutans. this compounds for the first time was isolated from the plants of genus allium. | 2015 | 10609303 |
| structure of steroidal saponins from underground parts of allium nutans l. | four steroidal glycosides including deltoside and nolinofuroside d and two novel saponins were isolated from underground parts of allium nutans l. on the basis of the spectral (lsims and nmr) analysis, the structures of the new compounds were established as 25r delta(5)-spirostan 3beta-ol-3-o-¿alpha-l-rhamnopyranosyl(1-->2)-[beta-d-glucopyranosyl(1 -->4)]-o-beta-d-galactopyranoside¿ and 25r delta(5)-spirostan 1beta, 3beta-diol 1-o-beta-d-galactopyranoside. on the basis of the extraction efficien ... | 1999 | 10552629 |
| an investigation into the antioxidant activity of allium nutans l. | antioxidants are important species which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. there is currently much interest in the antioxidant role of fruit, vegetables, wines and teas. in this study the antioxidant activity of leaf, bulb and root of allium nutants l. was investigated. biochemical parameters were also determined: activities of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, glutathione peroxidase), quantities of ... | 1999 | 10404542 |
