Antioxidant, Iron Chelating and Tyrosinase Inhibitory Activities of Extracts from Talinum triangulare Leach Stem
The aim of this work is to evaluate the antioxidant activity against the radical species DPPH, the reducing capacity against Fe II ions, and the inhibitory activity on the tyrosinase enzyme of the T. triangulare. Hydromethanolic crude extract provided two fractions after the liquid/liquid partition with chloroform. The Folin-Ciocalteu method determined the total phenolic content of the crude ex...
متن کاملAntioxidant Activities and Tyrosinase Inhibitory Effects of Different Extracts from Pleurotus ostreatus Fruiting Bodies
We evaluated the antioxidant activity and tyrosinase inhibitory effects of Pleurotus ostreatus fruiting bodies extracted with acetone, methanol, and hot water. The antioxidant activities were tested against β-carotene-linoleic acid, reducing power, 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity, and ferrous chelating ability. Furthermore, phenolic acid and flavonoid contents wer...
متن کاملEvaluation of the Antioxidant Activities and Tyrosinase Inhibitory Property from Mycelium Culture Extracts
Since mushrooms have many bioactive components, they have been used as components in folk medicine. Because mycelium has an advantage when it comes to large-scale production, this study aimed to evaluate the antioxidant properties and anti-tyrosinase activity from 55 mycelia in culture media. Relatively high 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity was detected from the ethanol ...
متن کاملAntioxidant activities and tyrosinase inhibition effects of Phaleria macrocarpa extracts.
BACKGROUND The ethyl acetate and chloroform extracts of stems, leaves and fruits of Phaleria macrocarpa were screened for their antioxidant capacity and tyrosinase inhibition properties. MATERIAL AND METHOD The total phenolic content (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric-ion reducing power (FRAP) were used to evaluate their antioxidant capacity. Tyrosi...
متن کاملPhenolic Content, Antioxidant Effects and Tyrosinase Inhibitory Activity of Extract of Some Stachys Species from Iran
Background: Given the importance of Stachys genus in Iran and their significant biological activity, we collected three species of this plant: St. aucheri Benth., Stachys benthamiana Boiss and St. inflata Benth. from different regions of Iran. We examined the free radical scavenging potential, total phenol content and tyrosinase inhibitory activity of their methanol, methanol 80% and dichlorome...
