Determination of Forty-Six Elements in Different Organs of Orychophragmus violaceus in Agricultural Farm

Orychophragmus violaceus has been used for food, oil, health care, feed and ornamental horticulture, but its elements components were less studied. The elemental composition in different organs of Orychophragmus violaceus were determined to provide technical support for its agricultural application. The results showed that (1) the contents of most nutrition elements in leaf and flower were higher than those in root, which proved that Orychophragmus violaceus is a good plant for green manure and feed, (2) the metal elements aluminium and lead were the highest in flowers of Orychophragmus violaceus; Ti, Cr, Ni, As, Sn and Tl were the highest in leaf of Orychophragmus violaceus; cadmium was the highest in root of Orychophragmus violaceus, which proved that Orychophragmus violaceus can be used for phytoremediation of soils contaminated by heavy metals except cadmium, and (3) the content of rare earth elements were generally low in Orychophragmus violaceus.
