In order to realize the above-mentioned purpose of the present invention, spy by the following technical solutions:
A kind of reducing the compositions that cadmium accumulates in Fructus Cucumidis sativi, including active component selenite and N-acetylcystein, the weight ratio of described selenite and N-acetylcystein is 1/5��3/7.
Fructus Cucumidis sativi grows under cadmium environmental condition, due to the coercion of cadmium, and ultra-oxygen anion free radical and hydroxyl radical free radical, the accumulation of plasma membrane Peroxidation Product in its meeting inducer blade, and cause the damage of the organelle structure such as cell Chloroplast. Additionally, Cd stress also can affect stability and the integrity of cucumber root meristematic cell nuclear membrane.
Selenium (Se) is the micronutrient element that human and animal's body is required, it is possible to increase cucumber growth speed, suppression Lipid peroxidation metabolism and increase oxidation resistance. Additionally, have antagonism between selenium and cadmium, when external source adds the selenium of low concentration, it is possible to decrease the Fructus Cucumidis sativi absorption to cadmium element, and within the scope of finite concentration, along with the rising of external source selenium concentration, the absorption of cadmium is declined by Fructus Cucumidis sativi. Selenate can reduce Cd accumulation amount, alleviate cadmium poisoning. Selenite is soluble in water, and after dissolving, Fructus Cucumidis sativi is easier to absorb, and the reduction effect of the Cd accumulation in Fructus Cucumidis sativi body is become apparent from. Additionally, based on the consideration of safety, Fructus Cucumidis sativi is as food, and the safety of human body is had considerable influence by selenium source therein, sodium selenite then has higher safety, and sodium selenite is cheap, and use cost is low.
