What Is Cytochalasin?

Phytoalexins are antibiotic-like substances produced by plants in response to environmental stress.

Cytochalasin

Various invading organisms, such as bacteria, viruses, fungi, and nematodes, can cause plants to produce cytochalasin. Plants can also induce cytochalasin when subjected to cold, ultraviolet radiation, physical damage, and pesticide treatment. These plants Induced ingredients are potentially toxic to animals. Many plant secondary metabolites such as

There are more detailed studies on cytochalasin produced by sweet potatoes. Cattle eaten rotten sweet potatoes causing severe respiratory distress, pulmonary edema, congestion and death. Several toxic terpenoids were isolated from rotten sweet potatoes, two of which were sweet potatoes Ipomeamaronoe and Ipomeamaronol. These two poisons can cause liver degenerative degeneration in laboratory animals with an LD50 of about 230 mg / kg body weight. Another isolated from the infected sweet potato sprouts Two kinds of cytochalasin are 4-sweet potato black scar diol (4-ipomeanol, LD50 is 38mg / kg body weight) and 1-sweet potato black scar diol (1-ipmeanol, LD50 is 79 mg / kg body weight) It is a cause of pulmonary edema. It is indistinguishable from the symptoms of acute toxicity caused by feeding mice with this substance and the symptoms of acute poisoning caused by eating rotten sweet potatoes.

Sweet potato, which is only slightly damaged by humans, also contains sweet potato scrofulone. Its content is 0.1 to 7.8 mg / g, which can cause certain toxicity. These toxic terpenes are stable under ordinary cooking conditions, but they are cooked in microwaves. Or in the case of baking, the content of sweet potato melanin in sweet potatoes will be reduced by 80% to 90%.
