Palha, espiga e estigma de milho foram extraídos com água, etanol aquoso, metanol aquoso e acetato de etila, respectivamente. O conteúdo fenólico total (TPC), conteúdo flavonóide total (TFC), conteúdo cetoesteróide total (TKC) e atividades antioxidantes [atividade de sequestro de radicais, poder redutor, e poder antioxidante-redutor férrico (FRAP) de 2,2’-difenil-1-picrilhidrazil (DPPH), 2,4,6-...

This study presents a comparison of the quality characteristics spearmint (Mentha spicata L.) dried by photovoltaic thermal dryer (PDS), shade (SDS), and an oven (ODS). The samples obtained were evaluated with respect to volatile compounds (VC), total phenolic (TPC) flavonoid content (TFC), antioxidant capacity (AC) chlorophyll contents. PDS had highest amount TPC, TFC AC, while SDS ODS did not...

The object of this study is to determine the best solvent and optimum extraction conditions for maximum phenolic compounds from Alchemilla vulgaris leaves. Extractions were carried out using solvents with different polarities. Box-Behnken Design was used optimize including time, temperature, liquid/solid ratio. In study, extract obtained acetone-water indicated highest total content (TPC), flav...

This study aimed to investigate the physiochemical properties of Sarawak's adapted Liberica coffee silverskin (CS) using multiple solvents (distilled water, methanol, and ethanol) its impact on total phenolic content (TPC), flavonoid (TFC), antioxidant activities CS. The results showed that highest TPC was observed in methanol extract (15.24 ± 0.65 mg GAE/g), while TFC recorded when extracted w...

Buckwheat is a precious source of various bioactive compounds like phenolics, flavonoids, rutin, and quercetin, etc. This research work was performed to harvest the nutraceutical potential indigenous buckwheat varieties their milling fractions (fine flour, coarse bran husk). Common (CBW) Tartary (TBW) were analyzed in terms total phenolic content (TPC), flavonoid (TFC), DPPH scavenging activity...

Kandelia candel, a mangrove belonging to the family Rhizophoraceae, whole plant is reported have anti-diabetic properties and was studied for evaluation of in vitro antioxidant antidiabetic study. Total Phenolic Content (TPC), Flavonoid (TFC) Alkaloid were quantitatively estimated by using standard protocols. The study evaluated activity extract method employed are DPPH radical scavenging assay...

The purpose of the present study was to investigate the effect of plant growth-promoting rhizobacteria(PGPR) on physiological and biochemical properties of maize (Zea mays L.) in different cultivation methods under water stress. The experiment was carried out as split-plot design including water stress (well-watered, mild stress, and severe stress) as main plot and also cultiv...

In this study, it was aimed to compare the antioxidant properties of extracts obtained from extraction olive leaves in Hatay province prepared with different solvents. For purpose, were extracted using pure methyl alcohol soxhlet and also by maceration 60% ethanol, 70% methanol, 90% acetone (v/v) distilled water. Total Flavonoid Content (TFC), Phenolic (TPC), Ferric Antioxidant Reducing Power (...

Purpose: Coconut testa is a byproduct of coconut industry and currently used for oil extraction. The partially defatted residue underutilized despite being able to convert into flour (CTF). objective the present study was compare bioactivity different solvent extracts CTF obtained from selected Sri Lankan cultivars namely, Gon Thambili (GT), Ran (RT), San Raman (SR), Tall×Tall (TT) commercial h...

Marine algae are becoming an interesting source of biologically active compounds with a promising application as nutraceuticals, functional food ingredients, and therapeutic agents. The effect drying (freeze-drying, oven-drying, shade-drying) extraction methods (shaking at room temperature, shaking in incubator 60 °C, ultrasound-assisted (UAE), microwave-assisted (MAE)) on the total phenolics c...
