1. The pterivegetables are uncultivated, edible pteridophyta with high nutrition.

2. The flavonoids of Pteridophyta and their systematic significance.

3. Objective To survey medicinal pteridophyta resources in Damu Mountain Nature Reserve Area.

4. Pteridophyta, with specific physiological enginery,[] is quite difficult to control.

5. The author simply analyzed the Pteridophyta resource, present situation, development and utilization in Sichuan Province.

6. In this paper37species wild medical spore medical plants from Jinyun Mountain was introuduced, including11species bryophyta plants and26species pteridophyta plants.

7. Results There are about 36 families, 58 genera and 107 species of medicinal pteridophyta.

8. There are 239 species under 88 families, in which 4 species are pteridophyta, 6 species are gymnosperms and 229 species are angiosperms. They can kill insects.

9. Conclusion Damu Mountain Nature Reserve Area is abundant in medicinal pteridophyta resources.

10. The flavonoids in 50 plants of 32 families of Pteridophyta?Gymnospermee and Angiosperm were listed. This work could provide the evidences of developing clinic function and plant division.
