Problems solved by technology

Currently commercially available SOD is extracted from human and animal blood, Escherichia coli (E.Coli), and plants, and the separation and purification procedures are complicated; the molecular weight is large, and it is not easy to transmembrane; the survival period is short, and it was only used in Japan for blood reperfusion in 1993.
Impossible to apply on crops due to high price

Abstract

A kind of antioxidizing pseudo-enzyme compounds and its preparing process and application are disclosed. Said compound has the activity of natural SOD and catalase (CAT) for removing O2 and H2O2, activating the self-protecting mechanism of plant and increasing yield of crops by 5.1-49.42%. Its advantages are good environment compatibility and acting as both agricultural chemical and trace-elementfertilizer.

Description

technical field [0001] The present invention relates to a class of antioxidative enzymatic compound with superoxide dismutase (superoxide dismutase, SOD) and catalase (Catalase, CAT) activity and its preparation and application as plant growth regulator, fungicide and trace element fertilizer . Background technique [0002] Superoxide dismutase (SOD) and catalase (CAT) are important metalloenzymes for plant antioxidant. When plants are under high temperature, cold, drought, waterlogging, salinity and other adversity stress or the invasion of pathogenic microorganisms, the plant defense system will produce a large amount of active oxygen (such as O 2 - 、H 2 o 2 and OH) to resist the stress of biotic and abiotic environments, but the accumulation of reactive oxygen species can damage lipid membranes and biological macromolecules such as nucleic acids and proteins. Antioxidant enzymes SOD and CAT can scavenge O 2 - 、H 2 o 2 , Protect membrane tissue and biological macr...
