Mineral Analysis of Purple Flowering Stalks

doi:10.7506/spkx1002-6630-201210035

Abstract

Abstract: The contents of Ca, Mg, Fe and Zn in different parts of 21 species of purple flowering stalks were determined by inductive coupled plasma emission spectrometer (ICP), and compared with seven cruciferous vegetables. The results showed that there were significant differences on Ca, Mg, Fe and Zn in different varieties of purple flowering stalks; their concentrations were also higher in leaf and bud than that in stem, which shows that the leaf and bud are of high nutritional values. Comparing with other cruciferous vegetables, purple flowering stalks had higher concentrations on Ca, Mg, Fe and Zn, which shows that purple flowering stalks are of high edible value.

Key words: purple flowering stalks, mineral elements, different parts, nutritional assessment
