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 کاملTyrosinase Inhibition, Antioxidant Activity and GC-MS Analysis of the Hexane Extracts of the Aerial Parts of Astragalus vegetus Bungi. and Gundelia turnifortii L.
Background: The enzyme tyrosinase is a copper-containing polyphenol oxidase, which is involved in melanogenesis. It catalyzes the conversion of tyrosine to melanin pigments in mammals. Tyrosinase plays an important role in enzymatic browning, which causes discoloration and loss economic value of many plant food products. This enzyme is widely distributed in fungi, higher plants and animals. Ob...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Antioxidant properties of palm fruit extracts.
Phenolic compounds have been shown to exhibit bioactive properties, and in particular antioxidant effects. A phenolic-rich fraction has been isolated from the aqueous by-product obtained during the milling of oil palm fruits. The objectives of the study were to determine the phenolic content of the crude and ethanolic extracts of oil palm fruits and to evaluate the antioxidant properties of the...
