Antioxidant Activity and Estimation of Total Phenolic Content by Colorimetry
The antioxidant potential of the 99% methanolic extract of leaves of Muntingia calabura was assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and total phenolic content was measured by Folin-Ciocalteau (FC) by Singleton and Rossi using Gallic acid and Tannic acid as the calibration standard. Moreover Muntingia calabura leaf extract showed strong reducing power and significant antioxidant a...
متن کاملOptimization of Reflux Conditions for Total Flavonoid and Total Phenolic Extraction and Enhanced Antioxidant Capacity in Pandan (Pandanus amaryllifolius Roxb.) Using Response Surface Methodology
Response surface methodology was applied to optimization of the conditions for reflux extraction of Pandan (Pandanus amaryllifolius Roxb.) in order to achieve a high content of total flavonoids (TF), total phenolics (TP), and high antioxidant capacity (AC) in the extracts. Central composite experimental design with three factors and three levels was employed to consider the effects of the opera...

Antioxidant Activity and Total Phenolic Content of Gagea fibrosa and Romulea ramiflora
Free radicals involved in a number of diseases due to the oxidative damage to DNA, lipids, and proteins and which can result in failure of cellular functions. Dried plant bulbs and leaves methanolic and ethanolic extracts were prepared. Total antioxidant activities of the methanolic extracts of Romulea ramiflora and Gagea fibrosa were determined using β-caroten-linoleic acid assay. Romulea-...
متن کاملAntioxidant Activity and Total Phenolic Content of Nerium oleander L. Grown in North of Iran
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...
