In vitro antioxidant activity of dewberry (Rubus caesius L. var. aquáticus Weihe. & Nees.) leaf extracts

Abstract: In this study, the antioxidant properties and total phenolic and flavonoid contents of Rubus caesius L. var. aqu?ticus Weihe & Nees leaf extracts were examined. The radical scavenging capacity of four leaf extracts (methanol, ethanol, acetone and aqueous) was estimated against 2,2-diphenyl-1-picrylhydrazil (DPPH) and 2,2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) assays. Total antioxidant capacity was tested by ferric reducing ability of plasma (FRAP) and total reducing ca… Show more

“…Leaves of Rubus species are used traditionally to treat diarrhea, hemorrhoids and skin problems [ 25 ], although polyphenolic profile, antimicrobial activity and hyaluronidase inhibition of extracts from young leaves and stems of Rubus caesius has not been fully analyzed. Our results confirm previous reports that European dewberry leaves can be used as a good source of strong antioxidants with pro-healthy properties [ 7 , 8 , 9 , 10 , 26 ]. However, the properties of antioxidant, antihyaluronidase and antibacterial activity of young stems and leaves of Rubus caesius , presented in this paper, are reported for the first time.…”

“…Samples collected in early spring, exhibited antioxidant and reduction ability that was better than leaf water extracts collected during summer in Poland [ 8 ], although weaker than the potential of ascorbic acid. The results obtained from leaves of R. caesius collected during summer in Serbia, could be explained by the different climatic conditions characteristic of this country (spring leaf extracts were not tested in that research) [ 9 ]. The IC 50 indicated the best results for both the DPPH test and ferric reducing abilities for water extracts from stems and leaves as well as stem ethanol extract (S-H 2 O > L-H 2 O > S-EtOH, Table 1 ).…”
