The essential oil from the aerial parts ofJurinea leptoloba DC., collected from Shiraz (South of Iran), was investigated for total phenolic content (TPC), antioxidant and cytotoxic effects. TPC of J. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg GAE/mg oil) using the Folin-Ciocalteau assay. The ferric reducing power of the oil was determined 0.117 ± 0.0...

Fourteen saxicolous lichens from trans-Himalayan Ladakh region were identified by morpho-anatomical and chemical characteristics. The n-hexane, methanol and water extracts of the lichens were evaluated for their antioxidant capacities. The lichen extracts showing high antioxidant capacities and rich phenolic content were further investigated to determine their cytotoxic activity on human HepG2 ...

Refining of edible and cosmetic oil consists various steps which include bleaching process. Bleaching is an important step as it removes colour pigments resulting in improvement taste appearance. In this work, activated bentonite marula shells were used to refine crude oil. Fresh was using H2SO4 whilst both KOH. Vacuum performed the shells. Fresh, activated, spent bentonites analysed X-ray Diff...

BACKGROUND Palm kernel cake (PKC), a by-product of the palm oil industry is abundantly available in many tropical and subtropical countries. The product is known to contain high levels of phenolic compounds that may impede the deleterious effects of fungal mycotoxins. This study focused on the evaluation of PKC phenolics as a potential cytoprotective agent towards aflatoxin B1 (AFB1)-induced ce...

total phenolic contents (tpc) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of artemisia biennis willd were measured in this work. the antioxidant activity was investigated by three different methods: β-carotene bleaching (bcb) test, 2,2-diphenyl-1-picrylhydrazyl (dpph) radical scavenging method and ferrous ion chelating (fic) assay. amo...

The in vitro antioxidant and antimicrobial activities of the essential oil and methanolic extract of Achillea sieheana Staf. (Asteraceae) were investigated in this study. The chemical composition of the essential oil isolated by hydro-distillation from the aerial parts of A. sieheana was analyzed by GC–MS. Camphor (43.36%), Artemisia ketone (25.95%), 1.8-cineole (6.29%) and camphene (4.77%) wer...
