In this study, we have examined the antioxidant activity and total phenolic content of different extracts (including water, methanol, water : methanol and acetone) of Nerium oleander L. grown in the north of Iran by employing various in-vitro assay, i.e. DPPH free radical scavenging, reducing power and total antioxidant capacity through the Mo (VI) reduction. The extracts showed different level...

This study was designed to examine the in vitro antioxidant activities and total phenolic contents of the methanolic extracts from male inflorescence of Salix aegyptiaca L. grown in Iran. The methanolic extract (ME) and its three fractions including water (WF), butanol (BF) and chloroform (CF) were prepared and then their antioxidant activities, as well as total phenolic contents, were evaluate...

4 different plant species belonging to the same family mint (Mentha piperita), sage (Salvia officinalis), rosemary (Rosmarinus lavender (Lavandula angustifolia) were harvested from Afyon region. Total antioxidant and phenolic contents analyzed by DPPH Folin-Ciocalteu method. The effect of extra virgin olive oils oxidation stability was tested means rancimat According analysis results, M. piperi...

Momordica charantia L. (cucurbitaceae), is a plant whose fruits are widely consumed in Chad. Seeds, green and ripe pulps of the this were subject study. The total polyphenols, antioxidants, flavonoids anthocyanins evaluated by Folin - Ciocalteu, DPPH, iron trichloride pH-differential methods respectively. polyphenol obtained 9.368 mg GAE/g for seeds extract, 9.068 pulp extract 8.505 mature extr...

Wine is a very rich source of polyphenols and essential elements which have multiple biological activities. This study evaluates the total phenolic content (TPC), antioxidant activity (AA) sixteen wine samples made from different grape varieties in territory Kosovo Metohija, mostly area Orahovac Velika Hoča. The obtained results, determined by using Folin-Ciocalteu assay, showed that wines Meto...

Waru leaf (Hibiscus tiliaceus) is plant that contains natural flavonoids and phenolic compounds useful as an antioxidant. Flavonoids phenolics can be extracted optimally if using a suitable extraction solvents. This study aims to determine the total flavonoid, phenolic, antioxidant levels of waru extract several The flavonoid content was tested AlCl3 colorimetric method, Folin-Ciocalteu DPPH me...

antibacterial, antifungal and antioxidant activities of methanolic crude extracts from aerial parts of four arnebia species namely arnebia fimbriopetala, arnebia linearifolia, arnebia garandiflora, arnebia tubata were screened. total phenolic contents were determined by folin-ciocalteu procedure and ranged from 2.2 ± 0.13 (a. fimbriopetala) to 1.6 ± 1.0 mg (arnebia tubata) gallic acid µmol equi...

Bu çalışmada, kırmızı turp (Raphanus sativus L.) kabuk ve içlerinden elde edilen polifenolik ekstraktların in vitro sindirim sırasında toplam fenolik madde miktarı (TFMM) antioksidan aktivitesindeki (AOA) değişim araştırılmıştır. Öncelikle, utrases su banyosu destekli ekstraksiyon (USDE) ultrases prob (UPDE), farklı ultrasonikasyon süreleri (20, 60, 180, 540 saniye) ile uygulanarak en yüksek TF...

Abstract Background: Binjai leaves (Mangifera caesia Jack. ex. Wall) or M. contain phenolic and flavonoid compounds important in medicinal plants development. The solvent difference fractionation will give various active substance concentrations. Objective: To evaluate the content qualitatively quantitatively from n-hexane fraction of binjai methanol extract. Methods: soxhletation method with w...
