Research Advance on Chemical Constituents and Anti-tumor Effects of Periplaneta americana L．

Abstract As a kind of traditional Chinese medicine with a long history，Periplaneta americana L ． has a variety of pharmacological activities such as anti-virus，anti-tumor，improving immunity，promoting tissue repair，anti-inflammation，analgesia and protecting liver ． In recent years，more and more people pay attention to the insect's development and utilization ． There are a number of quasi-famous drug which main composition based on P ． americana extracts have invested to the market (such as " Kangfuxin"， " Ganlong"， " Xinmailong") ． All these show that P ． americana have a huge medicinal potential ． Moreover，highly reactive chemical substances have huge application prospects in anti-tumor ． Based on the above，we review P ． americana researches from the chemical composition and anti-tumor effect in recent years，which is aiming at providing theoretical support and help for the drug's further development and utilization． Key words Periplaneta americana L．;Chemical composition;Anti-tumor effects;Research and developmen
