Screening of total phenolic content and radical scavenging capacity of Bulgarian plant species
2015
Georgieva, L | Mihaylova, D.
The antioxidant activities of nine Bulgarian plants have been investigated, in the light of recent scientific developments, throughout the world due to their potent pharmacological activities and food viability. In the present study, the possible radical scavenging activity of Clinopodium vulgare L., Cotinus coggygria Scop., Matricaria chamomilla L., Melissa officinalis L., Mentha peperita L., Origanum vulgare L., Salvia officinalis L., Sideritis scardica Griseb. and Thymus vulgaris L. was investigated using different antioxidant methodologies: radical scavenging activity by DPPH and ABTS radicals and reducing power. The extracts have been performed of the dried powered samples using heat-reflux extraction with 96 % ethanol and methanol, respectively. The total polyphenol content of the extracts was investigated as well. The experiments conducted revealed that the investigated plant species are potential sources of polyphenolic compounds and antioxidant activity.
