Abstract: Coumarins,also known as a large class of plant secondary metabolites, are present in remarkable amounts in plants, and their presence has also been found in animal and microorganisms sources.coumarins and their derivatives possess a wide range of biological activities. For instance, they have been claimed to be used as anti-bacteria, anti-HIV, anti-tumor, anti-inflammation, anti-coagulation and insecticidal activity and so on. The biological activities, photochemical and photophysical properties of coumarin derivatives, coumarin derivatives has been applied in various fields and has been the concern of scholars domestic and foreign.
