Acacia nilotica, indigenously known as ‘Babool’ of family Leguminosae has many traditional and ethnobotanical uses. All the parts tree are important seeds most abundantly available which rich in different phytochemicals. Thus, aim this study was qualitative quantitative analysis phytochemicals evaluation antioxidant activity nilotica seed along with their viz. cotyledon endosperm a potential so...

Previously, p-methoxyphenol fed in the diet was found to be the most potent inhibitor of benzo(a)pyrene-induced neoplasia of the mouse forestomach of 18 phenols investigated. In the present study, the effects of p-methoxyphenol on the directacting carcinogen, 0-propiolactone (BPL), were determined, pMethoxyphenol administered at 1 or 4 hr prior to BPL or fed in the diet markedly inhibited BPL-i...

The asymmetric reaction of a lithium enolate generated from a BHA (2, 6-di-tert-buty-4-methoxyphenyl) propanoate was allowed to react with benzaldehyde in the presence of a diether-type chiral ligand affording the corresponding anti-aldol product in a moderate enantioselectivity. A tetradentate ligand induced better enantioselectivity albeit relative loss of anti-selectivity. A variation of lit...

Antioxidant activities of Satureja boissieri extracts were detected by using specific in vitro techniques. Standard antioxidant compounds such as ascorbic acid, BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) were used to compare with the results obtained from ethanol and water extracts of the plant samples. Both extracts presented high antioxidant <span ...

Boids are primitive snakes from a basal lineage that is widely distributed in Neotropical region. Many of these species are both morphologically and biogeographically divergent, and the relationship among some species remains uncertain even with evolutionary and phylogenetic studies being proposed for the group. For a better understanding of the evolutionary relationship between these snakes, w...

BACKGROUND As a by-product of tropical fruit juice industry, passion fruit peel is a valuable functional food. It is rich in antioxidants. To determine its potential antioxidant properties of passion fruit peel, this study aimed to evaluate the effect of extraction conditions on total phenolic content and antioxidant activity. METHODS The extraction conditions were selected from different per...

Electrochemical oxidation of some p-substituted phenols (p-nitrophenol, p-hydroxybenzaldehyde, phenol, p-cresol, and p-methoxyphenol) with electron-donating and -withdrawing substituents was studied to reveal the relationship between the structure and the electrochemical reactivity of p-substituted phenols using a boron-doped diamond electrode by voltammetry and bulk electrolysis. Voltammetric ...

Reaction of BiPh3 or Bi(O(t)Bu)3 with benzohydroxamic acid (H2-BHA) results in formation of novel mono- and di-anionic hydroxamato complexes; [Bi2(BHA)3]∞ 1, [Bi(H-BHA)3] 2, [Bi(BHA)(H-BHA)] 3, all of which display nM activity against Helicobacter pylori. Subsequent dissolution of [Bi2(BHA)3]∞ in DMSO/toluene results in hydrolysis to the first structurally authenticated {Bi34} oxido-cluster [Bi...
