The present study aimed to estimate the individual and total phenols and antioxidant activity of the aqueous and alcoholic extracts of three premium quality date varieties (Khalas Sukkari and Ajwa) from Saudi Arabia In general water extract has shown significantly higher contents of total phenols than alcoholic especially in Ajwa (455 88 and 245 66 mg/100 g respectively)

Oct 28 2011The phenolic contents of methanolic extracts from five varieties of date palm (Phoenix dactylifera) fruits from Algeria Deglet Nour (DN) Degla Baidha (DB) Ghars (Gh) Tamjhourt (Tam) and Tafezauine (Taf) were measured in this work The antioxidant activities of these extracts were also evaluated Total phenolic content ranged from 41 80 to 84 73 mg

The total phenolic and total flavonoid contents were significantly higher in the leaves than the roots Additionally antioxidant activity was evaluated using ferric-reducing antioxidant power 2 2-diphenyl-1-picrylhydrazyl radical (DPPH) and trolox equivalent antioxidant capacity assays and was strongly correlated with phenolic compounds

Phenolic Contents and Antioxidant Activity of Various Date Palm (Phoenix dactylifera L ) Fruits from Saudi Arabia 1135 USA [22] An antioxidant which can quench reactive free radi-cals can prevent the oxidation of other molecules and may therefore have health-promoting effects in the pre-vention of degenerative diseases [23] The interest in

However the white Brazilian variety showed a significantly higher antioxidant capacity measured by the ABTS assay With regard to the phenolic content a difference was found between the samples which ranged from 55 5 to 95 5 g GAE 100 g −1 The colour of the grain was found as not related to a higher content of phenolic compounds

The aqueous extract of scraped coconut kernel is known as coconut milk Coconut milk preparations are also commercially available in the form of desiccated powders or liquids While these various coconut milk preparations are heavily used in cooking in the Asian countries as a major source of dietary fat limited studies have been conducted on their chemical and

Sterculia urens Roxb is highly exploited for karaya gum due to commercial demand but remained unexplored for its pharmacological values This work shows various secondary metabolites phenolic content antioxidant and antimicrobial potential of S urens root This primary information introduces a new arena for the discovery of bioactive ingredients useful for the
