1) A preliminary study on cytology of Chinese Pteris.

2) The spore morphology of Histiopteris and Pteris is very differential , put genus Histiopteris in family Pteridaceae is not suitable, according to the feature of spore morphology .

3) Objective To study the effect of herbal medicine Pteris semipinnata5F on the fibroblasts from systemic scleroderma(SSc)skin and explore new drug for SSc treatment.

4) The main genera are Pteris L. , Colysis Presl, Woodwardia Sm. , Selaginella Spring and Asplenium L. ,(http:///pteris.html) among which Pteris L. and Woodwardia Sm. have relatively intensive distribution.

5) By imaging - PAM , Photosynthetic performance of Pteris vittata was studied under Arsenic As stress.

6) Pteris multifida Poir is a tradition of medicinal plant, which has primely medicinal value and a widely using in the future.

7) The population genetic diversity of Pteris vittata from Guilin area, including GuilinCity, Yanshan Town, Yongfu County, was studied by allozyme electrophoresis method.

8) OBJECTIVE: To study the phytochemistry of Pteris semipinnata L. (PSL), and antitumor action of its active constituents and active fraction.

9) The spore morphology of Pteris is stable, and the difference between species is distinct , but the features of spore and sporophyte are not related.

10) The palynological assemblage characters reflect that ferns like Pteris trifur cata Ching can adapt the desert environment and has representativeness in these regions.

11) ConclusionThe extracts of the plants from Pteris are proved to be the antitumor active fractions in vitro.

12) The development process and spore sterile culture of Pteris wallichiana Agardh.

13) AIM:To study the active chemical constituents of Pteris multifida against growth of rat prostatic epithelial cells(PECs).

14) The latest progress on chemical constituents and pharmacological activity were reviewed in the paper. Main problems and study directions in future of pteris ...

15) The effects of different concentrations of arsenic on spore germination and rhizoid and prothallium growth of Pteris vittata under aseptic condition were studied.

16) Besides, pollen of Abies, Picea, Pinus, Tsuga, Betula, Ericaceae, Labiatae and Cyperaceae and spores of Pteris, Polypodium and Selaginella were also observed.

17) OBJECTIVE To develop a HPLC method for extracting and separating the diterpenoids from Pteris semipinnata L.

18) This method is highly effective and fast, which can be applied to research and develop for diterpenoids in Pteris semipinnata L as new antitumor drug resource.

19) The invention discloses a method for culturing the green spheroids of a pteris vittata and a special medium thereof.

20) Objective:To observe the effect of compound 6F isolated from Pteris semipinnata L. (PsL) on biosynthesis of DNA, RNA and protein in HL 60 cells and investigate its antitumor mechanism.
