Part1: Extraction method of amygdalin almonds
For the extraction of amygdalin, almonds or almonds can be heated in ethanol, then the solvent is evaporated and ether is added to obtain fine white amygdalin crystals. Liebig and Waller found that amygdalin decomposes to produce three products: sugars, benzaldehyde, and hydrocyanic acid. Subsequent studies have shown that amygdalin is decomposed into glucose, benzaldehyde and hydrocyanic acid catalyzed by sulfuric acid, while hydrochloric acid decomposes it into mandelic acid, D-glucose and ammonia. Under the catalysis of enzymes, amygdalin is decomposed in two ways: maltase decomposes it partially to generate D-glucose and mandelonitrile glucoside (C6H5CH(CN)O·C6H11O5), an isomer of phenylacetonitrile glucoside. body. Almondase can decompose it into benzaldehyde, cyanide and two molecules of glucose. This reaction occurs in bitter almonds, which usually contain free benzaldehyde and cyanide.
Part2: Efficacy and role
Almonds contain 3% amygdalin, which is decomposed by enzymes to form hydrocyanic acid. Hydrocyanic acid is toxic but a small amount has a sedative effect on the respiratory center. Therefore, it is recorded in the literature that it has antitussive and antiasthmatic effects, and has the effect of
killing typhoid bacillus and other fungi. In recent years, domestic and foreign scientific research has proved that hydrocyanic acid also has anti-cancer effects, which is really a good product for human health.
Biochemical analysis confirmed that apricot kernels and bitter almonds contain an active chemical substance called amygdalin. Amygdalin is composed of three components: glucose, benzaldehyde, and hydrocyanic acid. After eating amygdalin, it can produce phenylhydroxyacetonitrile and glucose after being digested and decomposed. Phenylhydroxyacetonitrile is then decomposed into benzaldehyde and hydrocyanic acid. Among them, hydrocyanic acid is a natural anti-cancer active substance, which only has a toxic effect on cancer cells, can kill cancer cells or inhibit their proliferation, and is not harmful to normal cells and healthy cells at therapeutic doses; benzene Formaldehyde has strong anticancer activity and can relieve the pain of cancer patients. Therefore, amygdalin can kill cancer cells in the human body and is an effective nemesis of cancer. According to the investigation of medical scientists, the residents of these areas, the intake of amygdalin in a day, greatly exceeds the intake of other countries in a year, this is the secret of their longevity without cancer.
The United States has used amygdalin for clinical use. They ate 250 cancer patients. Under normal therapeutic doses, 248 were cured, with a cure rate of 99%. 2 cases improved significantly, and more than 4,000 cancer patients have been cured. my country also uses amygdalin, or almond glutinous rice porridge, and almond tea to treat colorectal cancer, lung cancer, and esophageal cancer, and has achieved good results.
