In an attempt to develop the food composition table for Bangladesh, the nutritional composition of nine varieties of orange-fleshed sweet potato was analyzed together with total carotenoids (TCC) and total polyphenol content (TPC). Each variety showed significant variation in different nutrient contents. The quantification of the TCC and TPC was done by spectrophotometric measurement, and the p...

zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...

The hypothesis that eggshell colouration is a sexually selected trait of female birds is based on the fact that biliverdin, the pigment responsible for blue-green colours of the eggshell, is a potent antioxidant and that only females with high antioxidant capacity can deposit higher concentrations of biliverdin as eggshell pigment. Antioxidants (e.g. carotenoids, vitamins) are also abundant in ...

plants are always exposed to vast aspects of either environmental biotic or abiotic stresses and those stresses affecting the plant growth and therefore crop production. molecular and physiological mechanisms influence plant resistance to environmental stresses, therefore the identification of these mechanisms can be an important step in challenging the damages. in this study, plant physiologic...

Abiotic factors including thermal stress are suggested to exert constrains on sexual ornaments through trade-offs between sexual displays and physiological functions related to self-maintenance. Given the health properties of carotenoid pigments, carotenoid-based ornaments offer a relevant context in which to investigate the effect of environmental stress, such as ambient temperature, on the pr...

A vast amount of epidemiologic evidence suggests that a relatively high fruit and vegetable intake is associated with reduced risk of cancer (1). Although findings for breast cancer are less consistent than those for cancers at several other anatomic sites, including the mouth and pharynx, esophagus , stomach, and lung (1), a recent meta-analysis suggested that women with a relatively high vege...
