Abstract: Abstract: Nepenthes belongs to the family of carnivorous pitcher plant， which preys insects by its pitchers and uses pitcher fluid to digest preys as their nutrition source. The bioactive pitcher fluid was proven to be proteolytic enzymes by literatures， such as aspartic proteinase and chitinase. Besides， inorganic chemical components such as naphthoquinoes， free radicals and inorganic ions were also found in the pitcher fluid. The pitcher fluid was found possessing diverse medicinal functions known as antifungal， anticephalalgic， wound healing， anticancer， antihypertensive and anti-malaria， etc. In this article， we reviewed recent research progress on Nepenthes pitcher fluid compositions and biological activities， to the benefit of medical application.
