- Advances in analysis of phenolic compounds of salvia, thymus and lavandula plantsPublication . Pereira, Olívia R.; Afonso, Andrea Luísa Fernandes; Cardoso, Susana M.Salvia, Thymus and Lavandula are important genera belonging to the Lamiaceae family. Several species of these genera are widely used in culinary or in traditional medicine due to their claimed health-benefit properties. Notably, phenolic compounds are believed to be central constituents contributing for plant health properties and hence, they have been the focus of many investigations for the last decades. This chapter reviews the major and minor phenolic constituents found in Salvia, Thymus and Lavandula genera. Typically, plants of these genera are particular enriched in hydroxycinnamic acids, namely in distinct derivatives of caffeic. Moreover, they contain considerable amounts of flavones, which are mainly glycosidic forms of the flavonoids luteolin and apigenin. In turn, flavonols and flavanones are less abundant and/or widespread amongst Salvia, Thymus and Lavandula plants, although eriodictyol O-glycosidic derivatives can be frequently found in Thymus.
- Beneficial effects of Salvia plants: correlation with bioactive componentsPublication . Afonso, Andrea Luísa Fernandes; Alves-Silva, Jorge M.; Pereira, Olívia R.; Cardoso, Susana M.Plants of the genus Salvia, also known as sage, are distributed worldwide and are commonly used for distinct purposes in culinary, cosmetic and fragrance industry, as well as in traditional medicine. Scientific data supporting the health-beneficial properties of sage have been obtained in chemical and biological (in vitro and in vivo) models, mostly using phenolicenriched extracts and essential oils and/or their purified constituents. Phenolic compounds in sage mainly comprise caffeic acid derivatives depsides together with glycosidic derivatives of the flavones luteolin and apigenin. In turn, essential oils are enriched in monoterpenes and their oxygenated derivatives (e.g a-/B-pinene, 1,8-cineole, a-/B-thujone and linalool). This chapter reviews the antioxidant, anti-inflammatory, antitumor, neuroprotective and cardioprotective potential benefits of Salvia plants, as well as the correlation to its bioactive components.
