raspberry waste, obtained from two cultivars, meeker (erm) and willamette (erw) was subjected to evaluation antioxidants and antitumour activities as a potential source of phenolics. some phenolic acids and flavonoids were identified and quantified by hplc. antioxidant activity was tested by measuring ability to scavenge dpph• and •oh by esr spectroscopy. ic50dpph• varied from 0.67 for erm to 0...

Antioxidant compounds inhibit formation of free radicals, chelate catalytic metals, and scavenge free radicals in biological systems. In addition, antioxidants play a decisive role in prevention of numerous physiological dysfunctions, cancers, and metabolic disorders. This study sought to evaluate the antioxidant capacity and cytotoxic effect of grape seed extract (GSE), crocin (CRO), and pheny...

The plants of the genus Salvia synthesize several types of secondary metabolites with antimicrobial, cytotoxic, and radical scavenging activities and are used in the folk medicine of different countries. Eleven Salvia species including S. aegyptiaca, S. aethiopis, S. atropatana, S. eremophila, S. hypoleuca, S. limbata, S. nemorosa, S. santolinifolia, S. sclarea, S. syriaca, and S. xanthocheila ...

Two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of Salvia sharifii. The compounds were purified using several chromatographicmethods. Structural elucidation of the compounds was performed using their 1H and 13C-NMRdata, EI mass and UV spectral data. The co...

the current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of eremostachys azerbaijanica (labiatae) as well as analyzed the potent extracts using gc-ms. extracts of e. azerbaijanica in n-hexane, dichloromethane (dcm) and methanol (meoh) were prepared using a soxhlet apparatus. the antioxidant activity of the extrac...

  Background: Achillea talagonica (Asteraceae) is an endemic herbaceous plant in Iran with small yellow flowers and several times pinnately divided leaves in worm shape. The plant was found to be cytotoxic in our previous studies.   Materials and Methods: A. talagonica was collected in May 2005 from Talegan in north of Iran during the full flowering stage. Dried aerial parts of the plant were r...

Background and objectives: Juniperus excelsa is a flowering plant that has been applied as traditional medicine for treatment of various disorders such as dysmenorrhea, bronchitis and colds, jaundice and tuberculosis. The aims of the present study were analyzing J. excelsa essential oil and investigation of its cytotoxic activity on three breast cancer cell li...
