The positive health effects have been mainly due to the contributions of their natural antioxidant capacity. Chokecherry (Prunus virginiana), a unique fruit, is a member of the Rose family and native to North America. Here we demonstrate that chokecherry fruit with strong antioxidant capacity is available in Manitoba, and that its potent antioxidant potential can be developed for health benefits in value-added applications.These findings are useful for developing novel value-added antioxidant products from chokecherry because of its phytochemical profile associated with health protection and prevention of disease. The results provide evidence essential for breeding novel cultivars of fruit plants with strong natural antioxidants. http://precedings.nature.com/documents/1529/version/1 Tue, 22 Jan 2008 18:48:50 UTC The potential of Manitoba chokecherry as a source of high natural antioxidants hdl:10101/npre.2008.1529.1 2008-12-04 Trust Beta Nature Precedings 2008-01-22T18:48:50Z Manuscript Cancer Chemistry Plant Biology http://creativecommons.org/licenses/by/3.0/ http://precedings.nature.com/documents/1523/version/1 Colour has attracted the interest and attention of many of the most gifted intellects of all time. Ideas of early thinkers were not -and could not have been- grasped on a scientific level without knowledge of a kind that lay far in the future. One character that is being considered is the colourful surfaces of living tissues, which could hardly have been visualized without a corresponding reference to the microscale parallel. Millions of years before man made manipulated synthetic structures, biological systems were using nanoscale architecture to produce striking optical effects. Here we show the microsculpture of the adaxial surface of flower petals from the asphodel, the Stork’s-bill and the common poppy by using optical, scanning electron and atomic force microscopy. Microsculpture has been studied in leaves and pollen grains of higher plants. To the best of our knowledge imaging and nanoscale morphometry of petals has not been reported hitherto. Our findings on flower petals’ microsculpture may be linked with aspects on colour revealed from ancient literature. http://precedings.nature.com/documents/1523/version/1 Wed, 16 Jan 2008 19:51:03 UTC Visual perception of colourful petals reminds us of classical fragments hdl:10101/npre.2008.1523.1 2008-01-16 Sophia Rhizopoulou Nature Precedings 2008-01-16T19:51:03Z Manuscript Ecology http://creativecommons.org/licenses/by/3.0/
