Antioxidant Activity and Phenolic Content of Acanthopanax trifoliatus and Toddalia asiatica
نویسنده
چکیده
Decoction and 75% ethanolic extracts from the leaves of Acanthopanax trifoliatus (AT) and Toddalia asiatica (TA) were spectrophotometrically examined for antioxidant activity and phenolics content. Phytochemical characteristics of the decoction extracts were also investigated by thin layer chromatography (TLC). The leaf decoction extract of AT significantly exhibited the highest in vitro antioxidant activity determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay and the thiobarbituric acid reactive substances (TBARS) method. TA decoction and 75% ethanolic extracts significantly contained the highest amount of total phenolics and total flavonoids content, respectively. Analysis of the decoction extracts of AT and TA by TLC showed specific fingerprints composed of chlorogenic acid and rutin.
