Isolation of two cytotoxic diterpenes from the fern Pteris multifida.

چکیده
From aerial parts of the fern Pteris multifida Poir. (Polypodiaceae) two diterpenes, entkaurane-2 beta, 16 alpha-diol and ent-kaur-16-ene-2 beta, 15 alpha-diol, were isolated by repeated column chromatography using silica gel and silica gel impregnated with silver nitrate. The structures were confirmed by spectroscopic methods. Both compounds showed a moderate cytotoxicity to Ehrlich ascites tumour cells.

Anti-Neuroinflammatory ent-Kaurane Diterpenoids from Pteris multifida Roots.
Activated microglia are known to be a major source of cellular neuroinflammation which causes various neurodegenerative diseases, including Alzheimer's disease. In our continuing efforts to search for new bioactive phytochemicals against neuroinflammatory diseases, the 80% methanolic extract of Pteris multifida (Pteridaceae) roots was found to exhibit significant NO inhibitory activity in lipop...
متن کاملSpectroscopic Analysis of Arsenic Uptake in Pteris Ferns
Two arsenic-accumulating Pteris ferns (Pteris cretica mayii and Pteris multifida), along with a non-accumulating control fern (Nephrolepis exaltata) were grown in greenhouse conditions in clean sand spiked with 0, 20, 50, 100 and 200 ppm sodium arsenate. Spectral data were collected for each of five replicates prior to harvest at 4-week intervals. Fern samples were analyzed for total metals con...

Bracken fern (Pteris aquilina) mixed with a grain mixture (1:3 by weight) was fed to a group of 40 female 6-week-old Swiss mice intermittently every other week for a total experimental period of 60 weeks. Thirty-three mice survived 30 or more weeks and all developed lymphatic leukemia with multiple organ involvement. Additionally, 5 mice developed multiple pulmonary tumors. No urinary bladder o...

Cattle were fed a diet containing bracken fern in the continuation of a study of the urinary bladder neoplasms produced under these conditions. One of the cattle died of a traumatic pericarditis and had no bladder lesion at 485 days. The other six animals fed bracken fern for from 510 to 1920 days all had gross bladder neoplasms. Four of the six animals with gross bladder neoplasms had transiti...
