Currently, because of the many applications of ionizing radiation in human life, especially in cancer therapy, food preservation, agriculture, industry and energy, there is an urgent need to develop effective protection of non-toxic radiation agents. The existing radiation agents are dear and have side effects. Pharmaceutical raw materials suppliers are actively looking for new radiological substances. These include enzymes, anti-oxidants, nitrogen, melatonin, growth factors, gene therapy and heat. In addition, plants extracts as a new species of ants protect radiation, it has clear efficacy and fewer side effects. So it gets increasing attentions from radiation protective industry.

Citrus fruits and leaves are rich in materials radiation. Cluster glycosides main active ingredient, such as citric factors and naringenin. Compounds such as fruit and leaf dry weight by 5%. A class can improve citrus flavonoid glycoside capillary reduce and increase blood flow materials such as vitamin P. People are also the materials used in the fight against cancer and the known anti-ulcer. Naringenin showed strong antioxidant activity of factors I take lemon and red blood cells, red blood cells, micro-nuclear frequency and bone marrow of mice to protect.

Peppermint is an aromatic herb with a role in the treatment of nausea and vomiting. Research has shown that γ-radiation increased peppermint orally, in fact, radiation-induced formation of spleen colonies drops peppermint endogenous mouse spleen weight was significantly the survival of chromosomal damage to bone marrow improves blood values ​​increased.

The Orchid herbal medicines are widely used in Indian systems of medicine. For treatment of infections, skin diseases, coughs and colds, etc., and the treatment of liver diseases and malaria, as well as antibacterial and antiviral chemotherapeutic agents and antioxidants, and immune system. Water and alcohol extract of leaves, the symptoms of radiation, the aqueous extract effective in improving survival. In order to protect than traditional radio protector WR-2721 A and their descendants to the ants standard radiation. Cited the main ingredient Polygonum Flavin Oriental scent of orchids, culture and race off. Experiments have confirmed that these two drugs, drugs with little or no toxicity.

Podophyllum may reduce the radiation damage, in particular the role of radiation-induced hemopoietic syndrome, to reduce the adult mice. Increased activity of superoxide dismutase in the intestine, liver, and SOD-GST. Prevention of neonatal rat uterus radiation-induced neuronal damage. Podophyllotoxin is the main component of podophyllum plant extracts.

In the study of experimental medicine radiation injuries, natural plant extracts have low toxicity, fewer side effects and other advantages. So it gets great opportunities in markets. In order to support natural plant extracts, the study and development of new anti-radiation effects are very important. Source:http://www.cospcn.com
