BackgroundMany members of the genus Satureja have aromatic and medicinal characteristics. ObjectivesObjectivesThe purpose of the present work was to determine cytotoxic activity of the essential oil of S. intermedia CA Mey (Lamiaceae) on two human cancerous cell lines and its in vitro inhibitory effects against 11 pathogenic bacteria and fungi as well.Materials and MethodsThe essential oil was isolated by hydrodistillation and analyzed by combination of capillary GC-FID and GC-MS. The in vitro toxicological study was based on the MTT cytotoxicity assay and antimicrobial activity of the essential oil was studied according to the disc diffusion method and MIC value.ResultsThymol (34.5%), γ-terpinene (18.2%) and ρ-cymene (10.5%) were the main components of the essential oil. The toxicological study on 5637 and KYSE cell lines showed IC50 values of 156 μg/ml. The essential oil exhibited considerable antimicrobial activity on tested bacteria and fungi.ConclusionsFrom the results of the present study, it may be concluded that the essential oil of S. intermedia and its major constitutes are interesting in antibacterial and anticancer applications.
Froriepia is a ditypic genus in the subfamily Apioideae. Froriepia subpinnata occurs in Iran and the Caucasus, while F. gracillima is a species endemic to Turkey that is known only from the type specimen collected near the country's eastern border. Although many comprehensive phylogenetic studies of members of the family Apiaceae have been conducted, the phylogenetic position of Froriepia has remained unknown. When we examined this genus in detail, we suspected that the two species assigned to it may in fact belong to separate genera because of morphological differences between them. To understand the tribal classification of this genus and to reveal its infrageneric phylogenetic relationships, we examined its members morphologically and phylogenetically. We obtained phylogenetic relationships by Bayesian inference and maximum likelihood analyses of internal transcribed spacer (ITS) and rps16 intron gene sequences. We also examined pollen ornamentation and seed surface sculpturing with scanning electron microscopy. We found that, while F. subpinnata is a member of the tribe Pyramidoptereae, F. gracillima is a member of the tribe Selineae, and this conclusion was supported by our analyses of both the ITS and rps16 intron sequences. When we evaluated all of our results together, we deduced that F. gracillima should be removed from Froriepia. Ultimately, in light of both differences in morphological characteristics and phylogenetic evidence, we describe a new genus, Yildirimlia. The taxonomical diagnosis, detailed description, and illustrations of the new genus are provided herein.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
