In the synthesis of natural products and active polysaccharides, 3,4-di-O-acetyl-L-rhamnose is an important raw material. Current synthesis methods have the disadvantages of expensive raw materials, cumbersome operations, and the need for separation and purification of intermediate products. On March 8th, I learned from the Science and Technology Department of Chengdu Institute of Biology Licensing. The invention first reacts L-rhamnose with acetic acid and acetic anhydride under the catalytic...

Abstract: The content of synephrine and naringenin in Fructus Aurantii was determined by capillary electrophoresis. Under the condition of 30 mmol·L-1 borax buffer solution (p H 10. 0), effective separation of the tested components was achieved. The content of synephrine in Fructus Aurantii was measured as 0.724 2 mg · g-1 with a relative standard deviation of 5.9% (n = 5); the content of naringenin was 0.904 7 mg · g-1, The relative standard deviation is 3.8% (n = 5). The average recovery of...
Orange juice production is the main driving force and direction of the development of China's citrus industry. A large number of epidemiological and animal studies have shown that citrus fruits have antioxidant, anti-cancer, prevent circulatory diseases, anti-allergy and antibacterial effects. This is mainly because citrus contains flavonoids based on flavanones (80%), of which hesperidin and naringin are the most important flavonoids in citrus. Hesperidin has anti-oxidant, anti-inflammatory...
