Abstract: Lycophytes and ferns are unique and charismatic members of many terrestrial ecosystems and occupy the pivotal position in land plant origin and evolution. The Chinese lycophytes and ferns flora, with approximately 2000 species, contributes a substantial component to the global lycophytes and ferns diversity, with estimates of 12 000 species. Among them, about 433 species are medicinally recorded and researches based on their phytochemical properties are important topics in natural medicines. This paper reviewed the research history and current status of chemical constituents and biological activities of lycophytes and ferns, which had highlighted the research progress of our group.
