Comparative evaluation of antioxidant activity in several perennial onion

Evaluation of biochemical characteristics of 8 perennial Allium species is achieved (A. ramosum, A. caeruleum, A. erubescens, A. obliquum, A. moly, A. aflatunense, A. oreophilum and A.ursinum). High nutritional significance of separate decorative species is demonstrated. A. caeruleum is shown to be a leader in the accumulation of ascorbic acid (more than 9000 mg/100 g d.w.) and polyphenols (more than 8000 mg GAE/kg d.v.). Detected ascorbic acid concentration range for 8 studies Allium species was 568 (A. ramosum) - 9980 (A. caerulum) mg/100 g d.w.; polyphenols 1392 (A. obliquum) - 8582 (A. caerulum) mg GAE/kg d.w.; water-soluble compounds 28 (A. aflatunense, A. obliguum) -69 (A. ramosum) mg/kg d.w.; chlorophyll 0.54 (A.oreophilum) - 1.69 (A. ursinum) mg/100 g d.w.; carotene 0.07 (A. oreophilum) - 0.25 (A.ursinum) mg/100 g d.w.; selenium 72 (A. ursinum) - 245 μg/kg d.w., (A. ramosum). Adequate consumption level of vitamin C may be provides by 6.2 g of A.caerulum leaves...
