ABSTRACT
Nepetoideae is the most diverse subfamily of Lamiaceae, and some species are well known for their culinary and medicinal uses. In recent years, there has been growing interest in the therapeutic properties of the species of this group regarding inflammatory illnesses. This study aims to collect information on traditional uses through ethnobotanical, pharmacological, and phytochemical information of the subfamily Nepetoideae related to inflammatory diseases. UNAM electronic resources were used to obtain the information. The analysis of the most relevant literature was compiled and organised in tables. From this, about 106 species of the subfamily are traditionally recognised to alleviate chronic pain associated with inflammation. Pharmacological studies have been carried out in vitro and in vivo on approximately 308 species belonging to the genera Salvia, Ocimum, Thymus, Mentha, Origanum, Lavandula, and Melissa. Phytochemical and pharmacological evaluations have been performed and mostly prepared as essential oil or high polarity extracts, whose secondary metabolites are mainly of a phenolic nature. Other interesting and explored metabolites are diterpenes from the abietane, clerodane, and kaurane type; however, they have only been described in some species of the genera Salvia and Isodon. This review reveals that the Nepetoideae subfamily is an important source for therapeutics of the inflammatory process.
ABSTRACT
Menthinae, one of the five subtribes of Mentheae (Lamiaceae), with ca. 735 species, is represented in Brazil by a wide range of herbs and shrubs. During an investigation of the taxonomic history of the group for the Flora e Funga do Brasil project, several nomenclatural issues with typifications in the group have been identified. This study attempts to resolve them, making suggestions of new types and re-evaluation of synonyms. Thirteen lectotypifications and one neotypification are being proposed, along with the recognition of Thymus selloi Spreng. ex J.A.Schmidt as a nomen nudum. Most of the suggested changes are due to the loss of many of Sellow's types at B during WWII, lack of specific herbaria references and collector numbers in the protologues, or to existence of designated syntypes in the referred collections. Our study is a contribution to the nomenclatural and taxonomic knowledge of Menthinae, providing a stable foundation for future study of its taxonomy, biogeography, and evolution.
