Notwithstanding the wide range of biological and pharmacological activities reported for sweet basil (Ocimum basilicum L.), many discrepancies are still present in the evaluation of its health-promoting properties. These discordances could be at least in part to not sufficient details of qualitative and quantitative composition, connected to the ample variability of this species. Furthermore, many investigations have been carried out in vitro, with few data available on the effectiveness in biological systems. In this study, the protective effect of essential oils and water soluble extracts derived from three different cultivars of sweet basil has been evaluated in cultured cardiomyocytes. To verify the effectiveness of supplemented oils/extracts in counteract oxidative damage, cardiomyocytes were stressed by the addition of hydrogen peroxide. The results obtained clearly indicate that essential oils have powerful protective activity against oxidative stress, whereas aqueous extracts are ineffective.

Abstract

Notwithstanding the wide range of biological and pharmacological activities reported for sweet basil (Ocimum basilicum L.), many discrepancies are still present in the evaluation of its health-promoting properties. These discordances could be at least in part to not sufficient details of qualitative and quantitative composition, connected to the ample variability of this species. Furthermore, many investigations have been carried out in vitro, with few data available on the effectiveness in biological systems. In this study, the protective effect of essential oils and water soluble extracts derived from three different cultivars of sweet basil has been evaluated in cultured cardiomyocytes. To verify the effectiveness of supplemented oils/extracts in counteract oxidative damage, cardiomyocytes were stressed by the addition of hydrogen peroxide. The results obtained clearly indicate that essential oils have powerful protective activity against oxidative stress, whereas aqueous extracts are ineffective. Variation among different cultivars have also been detected, and related to composition.
