摘要：

Achyroctine satureioldes is widely used, along Argentina, Brazil and Uruguay, in popular medicine. In this study we compared the total phenolic content, expressed as gallic acid equivalent/g (mg of GAE/g of sample), using methanolic extracts of A. satureioides flowers collected in different zones of Argentina. The extracts were also tested for their antioxidant activity monitoring the bleaching rate of 1,1-diphenyl-2-picrylhydrazyl (DDPH). The polyphenol content, as well as the scavenging activity showed a great variability (23.0-112.6 mg GAE/g and DPPH IC50 4.47-23.98 mu g/ml) depending on the origin of the samples. Interestingly, the phenolic content correlates with scavenging activity, but the results also indicate that cultivations of this medicinal plant should be necessary in order to assure uniformity and quality.
