The air dried powdered plant materials were extracted with different organic solvents, screened for phytochemicals and analyzed for their biological activities. The antioxidant potential was evaluated by scavenging of DPPH radical, TPC and TFC, while antimicrobial activity by disc diffusion assay against a set of bacterial and fungal strains. Ethylacetate extracts showed higher free radical sca...

This study aimed to assess the optimal extraction parameters, solvent-to-solid ratio, and time, for ultrasound-assisted of Satureja montana L. (winter savory) harvested from a 6-year-old experimental plantation. The optimization was performed in order acquire extracts that are rich content polyphenols (TPC), flavonoids (TFC), proteins, also exhibit strong antioxidant activity, while maintaining...

The present study was designed to develop and evaluate the nutritional, functional, sensory properties texture profile data of garlic peel powder fortified viz. 2%, 5% 10% value added pukhelein compared with control sample. Garlic showed crude fiber, carbohydrate ash content 60.57%, 21.71% 16.34%, total phenolic (TPC) 108.79 µg/ml GAE, flavonoid (TFC) 33.27 mg Quercetin/ml antioxidant activity ...

Fabaceae are associated with a high antioxidant activity (AA) and total phenolic (TPC), flavonoid (TFC), selenium content (SeC). In this study, the aqueous extracts from ten species that medicinally used by Aucan Tribal Peoples Suriname (South America), were evaluated for AA using DPPH FRAP assay, TPC, TFC, SeC Folin-Ciocalteu’s, an AlCl3 colorimetric, azure B-based method. Associations between...

Purwoceng (Pimpinella pruatjan) is an Indonesian native plant but difficult to cultivate. Hydroponics can be used as a solution for purwoceng cultivation. Hydroponic types and nutrient concentrations affect purwoceng’s productivity. This study aimed determine total phenolic content (TPC) flavonoid (TFC), changes in steroid, antioxidant capacity due two hydroponic (nonrecirculating recirculating...

Extraction parameters in classical solvent extraction of bioactive compounds from Arbutus unedo leaves were studied using a single factor experiment approach. Effects ethanol (EtOH) concentration (20-100 %), solvent:solid ratio (10-90 ml/g), time min) and temperature (15-70 °C) on total phenolic content (TPC), flavonoid (TFC) antioxidant activity (TAA) the extracts investigated. The optimal con...

Propolis samples were collected from four different regions of Lebanon characterized by high biodiversity and honey production. The analyzed for their total phenolic contents (TPC), flavonoid (TFC), chemical profiles, antioxidant activity. TPC was determined using Folin-Ciocalteu method while the TFC AlCl3 method. activity propolis examined two methods, namely free radical scavenging assay redu...

This study was conducted to compare the correlations between free radical antioxidant activity and anti-wrinkling activity. Areca nut extracted using various concentrations of ethanol (0, 40, 80, 100%) methanol at 100 °C for 90 min. The ethanolic methanolic extracts were evaluated total phenolic content (TPC), flavonoid (TFC), activity, including capacity (TAC), FRAP, DPPH, ABTS, superoxide ani...

A set of supercritical extractions (SCE) using carbon dioxide (CO2) has been performed on Solanum nigrum Linn. design experiment (DoE) Box-Behnken was applied to investigate the influential parameters SCE. The relationship between extraction (i.e., temperature, time, and pressure) products phenolics-TPC, alkaloids-TAC, flavonoids-TFC) evaluated. It found that temperature pressure are most influ...

The objective of this research was to evaluate some quality-defining physicochemical parameters (moisture, specific gravity, pH, free acidity, ash, electrical conductivity, total phenols, and flavonoids content, K, Ca, Mg, Na, P) seven Romanian monofloral honeys (linden, acacia, rapeseed, sunflower, mint, raspberry, chestnut) collected in 2017. investigated quality are mainly within the recomme...
