[Advances in study on chemical constituents and pharmacological activities of plants of genus Pteris].

The main chemical constituents in plants of genus pteris include diterpenoids, diterpenoid glycosides, flavonoids, flavonoid glycosides, sesquiterpenoids and volatile oils, etc. Some of extracts show the following activities, such as antitumor, antifungi and antibacteria. Some of compounds have inhibitory effect on platelet aggregation and antiinflamatory action. The latest progress on chemical constituents and pharmacological activity were reviewed in the paper. Main problems and study directions in future of pteris were indicated.
