Plants and plant derived products exert chemopreventive effects on various cancer cell lines by the induction of cell death mechanisms. The effects of root acetone extract of Rubus fairholmianus (RFRA) on the proliferation of human colorectal cancer (Caco-2) cells have been investigated in this study. The extract led to a dose dependent decrease in both viability and proliferation and increased...

abstract   extract prepared from aerial part of pycnocycla spinosa is a relaxant of rat ileum contractions. the objective of this research was to study the spasmolytic activity of p. spinosa root extract for comparison with the aerial part extract. hydroalcoholic extracts were prepared by percolation method. a portion of rat ileum was removed and suspended under 1 g tension in tyrode’s solution...

The Patagonian currant Ribes magellanicum is highly valued due to its pleasant flavor and sweet taste. The aim of this study was to characterize its constituents and to assess their antioxidant and cytoprotective properties. For the fruit phenolic-enriched extract (PEE), total phenolics (TP), total flavonoids (TF), and antioxidant activity (DPPH, Ferric reducing antioxidant power (FRAP), and Tr...

Alaska’s domesticated and native Ribes and Rubus genera have virtually gone unchecked for pathogen detections. Cultivated Ribes species are predominantly found in home gardens and landscape areas along highways and in cities. In 2008, while surveying native plants for diseases in North Central Alaska near the town of North Pole, mottled leaves were readily visible on wild raspberries (Rubus str...

statement of problem: it is necessary to use irrigation solutions during cleaning and shaping of root canals to efficiently reduce the number of micro organisms. sodium hypochlorite is used as an effective antibacterial endodontic irrigants. however, the extract of pennyroyal plant has also shown anti-bacterial characteristics comparable with antibacterial drugs. objectives: to compare the anti...

Data from Loasaceae and Ribes (Grossulariaceae) obtained during field studies in Peru allow us to define the southeastern limit of the Amotape-Huancabamba Zone with remarkable precision. The limit runs in slightly southeasterly direction from NE of Otuzco (department La Libertad, province Otuzco, Río Chicama drainage system: S 07° 50,315 ́, W 078° 29,076 ́) to the mountain pass between Parcoy and...

Influenza, a respiratory disease caused by influenza viruses, still represents a major threat to humans and several animal species. Besides vaccination, only two classes of drugs are available for antiviral treatment against this pathogen. Thus, there is a strong need for new effective antivirals against influenza viruses. Here, we tested Ladania067, an extract from the leaves of the wild black...

Oral administration of Embelia ribes berries (50% EtoH) reduced blood sugar level significantly. In intact rats, blood sugar levels were decreased by 13.1% and 20.3% after 3 hrs. and 5 hrs. of treatment respectively. While in alloxan induced diabetic rats blood glucose levels were decreased after 3 hours and 5hours by 28.1% and 34.5% respectively. Hypoglycaemic action of Embelia ribes berries m...
