The paper aimed to study the influence of naphthalene acetic acid (NAA) and ethephon on total phenols, flavonoids and tannins as a function of seasonality in Echinodorus grandiflorus plants. The experiment used adventitious plantlets from the flower stem with 4 to 5 leaves, planted in 10-liter pots. The leaf spray treatments applied were: control, NAA 100 mg L -1 , and ethephon 100 mg L -1 . Tr...

Article history: Received on: 25/12/2013 Revised on: 08/02/2014 Accepted on: 23/05/2014 Available online: 28/06/2014 The effect of tissue cultured and tissue culture derived Mentha species viz. Mentha piperita(PPR611), Mentha arvensis (SH) and Mentha spicata (SPR 8) on antioxidant potential using lipid peroxidation model was studied. The extracts prepared were analyzed for total phenols and fla...

The antioxidant activity, total phenols content and phytochemical constituents of edible portions of four underutilised tropical fruits; Irvingia gabonensis (African mango), Artocarpus altilis (breadfruit), Annona muricata (soursop) and Annona squamosa (sweetsop) were determined. Extracts of fruit samples were screened for selected phytochemicals using standard methods whereas the total phenols...

Over the past decade, the chemical behavior of flavonoids as antioxidants has become the subject ofintense experimental research. In this paper, we use a quantum-chemical approach to shed light on thereactivity of four poly phenols, Benzoic acid, vanilic acid, gallic acid and flavone . In order to establishthe most efficient theoretical methodology, different methods, either Hartree—Fock-based ...

Orange peel molasses, a byproduct of juice production, contains high concentrations of phenols, including numerous flavanone and flavone glycosides, polymethoxylated flavones, hydroxycinnamates, and other miscellaneous phenolic glycosides and amines. Extensive fractionation of these phenols was achieved by adsorption, ion exchange, and size exclusion chromatography. Size exclusion chromatograph...

The extractive efficiency of phenolic compounds from plant material is greatly depended on the solvent. In our research, methanol and ethanol were used for taking out the phenols from green walnut fruits. The total phenolics and some individual phenolics, such as gallic, chlorogenic, ellagic, sinapic and protocatechuic acid, (+)-catechin and juglone were detected. Total phenolic contents were d...

Bisphenol A (BPA) and alkylphenols (APs) are well-known endocrine disrupting chemicals (EDCs) which may threat the next generations' health. We performed biomonitoring of these phenols in colostrums to assess risk of the phenols in breast-fed neonates. Study subjects were the lactating mothers who delivered babies within 2 weeks (N = 325; 30.67 ± 3.45 years) and their neonates (N = 326; embryon...
