Antiradical Activities and Cytotoxic Effects of Phlomis Brevibracteata Turrill on SK-HEP-1 Adenocarcinoma Cell Line

Abstract

The present study investigates the total phenol amount, radical scavenging and anticancer activity of methanolic extract of Phlomis brevibracteata Turrill (PBT) leaves; an endemic plant of North Cyprus. The antiradical activity and cytotoxicity of 70% methanolic extract of PBT leaves were analyzed by the implementation of DPPH, ABTS radical scavenging activity tests and MTT assay, respectively. Our results showed significant antiradical scavenging activity in the total phenolic content of the PBT leaves. MTT assay proved potent cytotoxic activity against SK-HEP-1 cell line not only for 70% methanolic extract of PBT, but also for gallic acid and caffeic acid constituents of the total phenolic extract.
