10-Hydroxy-2-decenoic acid(CAS#765-01-5)
| introduction | royal jelly is a kind of milky white or light yellow, slightly sweet and slightly sour viscous liquid secreted by nutrient glands of worker bees head. it has physiological effects such as enhancing body resistance, antibacterial and anti-inflammatory, and has high nutritional value. Therefore, royal jelly has been widely valued by people. As early as 1888, the general components of royal jelly were discussed, and it was recognized that most of the royal jelly ether extract was an organic acid with no optical activity, and the chemical formula was C10H18O3. This organic acid was identified as 10-Hydroxy-2-decenoic acid, confirmed to have a trans structure. 10-Hydroxy-2-decenoic acid is unique to royal jelly, so it is often called royal acid (roaljelly). |
| physical and chemical properties | a white crystal with a melting point of 58~59 ℃, stable properties, easily soluble in methanol, ethanol, chloroform and ether, slightly soluble in acetone, hardly soluble in water, acidic to litmus paper, rapid fading of bromine water and fading of potassium permanganate solution, but it does not show purple red for ferric chloride. |
| use | royal acid, as a substance with various physiological activities, is often used to measure the quality of royal jelly, and is also widely used in health food and beverages. it has special effects in treating certain diseases, it also has the ability to regulate and improve the body’s immune function and resist radiation injury. A large number of antibacterial tests show that pure bee king acid has strong antibacterial effect on Escherichia coli and pyogenic cocci. Domestic studies have also shown that the combination of bee king acid, chemotherapy and radiotherapy for patients with malignant tumors has a significant effect on immunity, increasing white blood cells and improving clinical symptoms. Studies at home and abroad have also shown that bee king acid has obvious preventive and medical effects on acute radiation. In view of the medical effect of royal jelly, the content of royal jelly has always been the main index to measure the internal quality of royal jelly. Japan has also adopted this index since 1980 and stipulated that the content of royal jelly in imported royal jelly should not be less than 1.9%. The nutritional value and medical value of queen bee acid have been continuously confirmed, and people’s understanding of it has been deepened. The demand for food and medicine has increased sharply. Therefore, the production of queen bee acid has a very broad prospect. |
