Total phenolic content and antioxidant activity of Salvia spp. exudates

Nat Prod Commun. 2012 Feb;7(2):201-2.

Abstract

The total phenolic content and antioxidant activity of 6 Salvia spp. exudates were measured to find new potential sources of natural antioxidants. Total phenolic content was assessed by a modified Prussian blue method, and the antioxidant activity by two methods: 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging capacity assay and lipoxygenase inhibitory assay. The total phenolic content ranged between 1.3 microg/mg DW (S. fallax) and 74.0 microg/mg DW (S. cacaliaefolia). In the DPPH test, S. cacaliaefolia was more effective than BHT, while in the inhibition of lipid peroxidation all the extracts presented good antioxidant capacity.
