In this study, antioxidative activities of aqueous extract of Biarum bovei (BBE) in stabilizing of canola oil during storage at 20°C was evaluated. For this purpose, the total phenolic (TP), flavonoids (TFC), and tocopherol content (TTC) of the extract were determined and β-carotene bleaching system was used to assess the antioxidant efficacy of BBE. The amount of TP, TFC, and TTC in BBE indica...

Objective: The aim of the present work was to assess the total phenolic content (TPC), total flavonoid content (TFC), and total alkaloid content (TAC) of crude hydro-methanolic seed extract of Abrus precatorius L. which is one of the beautiful seed bearing plant belonging to family Fabaceae and used extensively in many Ayurvedic preparations with significant therapeutic significance. Methods: T...

Turbulent-flow chromatography (TFC) on-line coupled to liquid chromatography mass spectrometry (LC-MS) is used to determine flavonoids and resveratrol in different types of wines. A fully automated system was developed in which 10 mL of sample (diluted wine) was passed over a TFC column, after which the retained analytes were separated by reversed-phase LC and detected by negative ion mode atmo...

A method for solving zero-finding problems is developed by tracking homotopy paths, which define connecting channels between an auxiliary problem and the objective problem. Current algorithms' success highly relies on empirical knowledge, due to manually, inherently selected paths. This work introduces a based Theory of Functional Connections (TFC). The TFC-based implicitly defines infinite fro...

This study aimed to investigate the antioxidant activity, total phenolic content (TPC), and flavonoid (TFC), as well profile of two species O. sanctum (OS) basilicum (OB). The TPC, TFC, cultivated sanctum's profiles were similar. TPC OS OB produced 386 383 mg gallic acid equivalent (GAE) per 100 g, whereas 201 203 quercetin (QE) g extract was obtained during TFC assay. activity extracts determi...

The ability of Leea philippinensis, an endemic tree in the Philippines, as in vitro free radical scavenger was investigated. Soxhlet extraction using solvents in increasing order of polarity (hexane<chloroform<ethyl acetate<acetone<methanol) yielded acetone and methanol extracts with the highest Total Phenolic Content (TPC) and Total Flavonoid Content (TFC). These crude extracts were further se...

This study was conducted to investigate the chemical and nutritional composition of Artemisia annua leaves in addition to determination of antioxidant potential of their extracts prepared in different solvents. Chemical composition was determined by quantifying fat, protein, carbohydrate, fiber, tocopherol, phytate, and tannin contents. Extraction of A. annua leaves, for antioxidant potential e...

Cinco complexos de ródio(II) de fórmula geral [Rh2(ponte)4] (ponte = acetato, propionato, butirato, trifluoroacetato e trifluoroacetamidato) tiveram suas afinidades em relação à albumina humana (HSA) determinadas por espectrofotometria, observando-se no caso dos alquilcarboxilatos uma correlação inversa com suas lipossolubilidades. A difusão dos complexos livres ou ligados à proteína para célul...
