detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
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...
Novel Piperidone Derivatives: Synthesis, Spectral and Evaluation of Antioxidant Activity
The present study was designed to synthesize isomeric alcohols from corresponding piperidone 1 by sodium ethoxide reduction and the alcohols were separated by column chromatography. The synthesized compounds were characterized by IR, 1H & 13C spectral studies. In addition to that in vitro potential antioxidant activity of the compounds were analyzed via DPPH assay and compared with standard ant...
متن کاملAntioxidant Activity of Xanthone Derivatives
Certain xanthone derivatives, such as these present in mangosteen fruits, show strong antioxidant activity. On the other hand, evidences accumulated that oxidative stress is involved in epileptogenesis. Therefore, the aim of the present study was to estimate total antioxidant capacity (expressed as a ferric reducing antioxidant power FRAP) and evaluate ability to scavenge free radicals (DPPH me...
