In this paper

the extraction methods and application of ricin were studied according to its toxicity characteristics. Ricin is a highly toxic plant protein with two polypeptide chains

including ricin

ricinine

ricin allergen and hemagglutinin. Ricin is mainly found in castor beans

and the ricin is the most toxic. At the same time

with the exploration of biomedicine in recent years

ricin

a kind of biological insecticide with “no residue” and “no pollution”

has been attached great importance. The use of ricin as a targeting agent has also received considerable attention. Therefore

the prospect of high purity extraction and utilization of ricin in biomedicine is very broad.
