<abstract xmlns="http://www.w3.org/1999/xhtml"> Salvia officinalis, L. (Lamiaceae) is one of the most widespread herbal species used in the area of human health and in the foodprocessing industry. Salvia and its extracts are known to be a rich source of antioxidants. As shown previously, the crude ethanolic extract of salvia (SE) exerts lower anti-oxidative properties in lard compared to the new salvia food formulations No. 1 (SF1; 32% of SE + 68% of the emulsifier Dimodan S-T) and No. 2 (SF2; 32% of SE + 68% of the emulsifier Topcithin 50).The aim of the present study was to investigate and compare the effects of the SE and its food formulations SF1 and SF2 on the toxicity and/or proliferation of L1210 leukemia cells. We found that SE and both SF1 and SF2 demonstrated different concentration- and time-dependent cytotoxic/antiproliferative cellular effects already within the first 24 h of the treatment. However, SE was nearly 10 times more effective than the new salvia food formulations SF1 and SF2.We investigated partially also the molecular mechanisms lying behind the action of SE, SF1 and SF2 induced apoptosis in our cell model. We found an apparent involvement of the mitochondrial/caspase-dependent pathway in the described processes. Nevertheless, further investigation is needed before salvia extract and its new antioxidant formulations can be included among the potential food antioxidants with protective properties against cancer.</abstract>
