Research On Extraction And Synthesis Of Capsaicin

Capsaicin is the essential pungent substance in the capsicum. It is a kind of vanilla-amide alkaloid. Because it is valuable in agriculture and industry, the research on it is flourishing. The capsaicin has many pharmacological activities, such as analgesia, relieving itching, sterilization anti-inflammation and so on, and the medicinal ointment prepared by capsaicin has been successfully pushed into the market. With the rapid development of the medicine, light and chemical engineering and food industry all over the world, the need for capsaicin in the domestic and international market has been increasing for years, the supply in the market falls short of demand.The extraction methods of capsaicin mainly contain ethanol method, acetone method, alkaline-acid method, supercritical carbon dioxide extraction method and so on. It was reported that Albright had tried on the preparation of capsaicin by cell culture techniques, Kaga made initial success in the synthesis of capsaicin by chemical method.In this paper a kind of white needle-like crystal was obtained via three steps...
