Abstract
In recent years, more and more patients with rheumatoid arthritis and neuralgia have been increasing year by year. Rheumatoid arthritis is a common acute or chronic connective tissue inflammation that often causes joint pain and muscle pain. Before the onset of rheumatism, there will be irregular moderate fever and even heart fatigue. The onset of neuralgia can be painful and difficult to bear, and the patient often has a sharp pain of needling, cutting, or burning. Rattan is a stem vine. It has the function of complex vein, pain, rheumatism. Main treatment rheumatism, rheumatoid arthritis, joint swelling pain, limb pain, numbness. In song and Ming dynasty, according to the records of "the grass in the picture" and "compendium of materia medica", "ivy has the symptoms of wind disease. Treatment of rheumatic fluid infusion, paralysis and other symptoms... ". In TCM, the pathologic mechanism of "arthralgia syndrome" and the function effect of Chinese herbal medicine on qingfengteng are clearly described, and the treatment of rheumatoid arthritis is the most significant.
This project is to explore the optimal extraction process optimization of the cyanine in the vine, and to be more scientific and effective to use the cyvine alkaloids in the vine, and to provide the experimental basis. The effect of different factors on the cyanine alkaloids in the vine was investigated by single factor test. In this paper, the optimum extraction process for the components of sinensis was selected by orthogonal test method for the factors that were more influential to the selection of ethanol concentration, ethanol consumption, ultrasonic time and ultrasonic frequency. The optimal extraction process of sinorine was A2B3C2D3, which was 70% ethanol concentration, 25ml ethanol, 25min ultrasonic processing time and 30Hz ultrasonic treatment.
Key words: Ivy; Sinomenine; High performance liquid chromatography; Orthogonal design
