Review of Studies on Phlomis and Eremostachys Species (Lamiaceae) with Emphasis on Iridoids, Phenylethanoid Glycosides, and Essential Oils (#)

As the sixth-largest Angiosperm family, Lamiaceae contains more than 245 genera and 7886 species that are distributed worldwide. It is also the third-largest family based on the number of taxa in Turkey where it is represented by 46 genera and 782 taxa with a high endemism ratio (44%). Besides, Lamiaceae are rich in plants with economic and medicinal value containing volatile and nonvolatile compounds. Many aromatic plants of Lamiaceae such as Salvia, Sideritis, Stachys, Phlomis, and Teucrium species are used in traditional herbal medicine throughout Turkey as well as in other Mediterranean countries. Salvia (Sage tea "Adacay"), Sideritis (Mountain tea "Dacay"), Stachys (Hairy Tea "Tuylu Cay"), and Phlomis (Turkish sage "Calba or Salba") are the largest genera that are used as herbal teas. This review focuses on the volatile and nonvolatile compounds of Lamiaceae from the genera Phlomis and Eremostachys of the subfamily Lamioideae with emphasis on iridoids, phenylethanoid glycosides, and essential oils.
