Sedative phytomedications continue to play an important role in the management of a considerable amount of anxiety symptoms because of the various side effects of synthetic sedatives and tranquilizers. However, developing new herbal drugs needs their appropriate quality control according to the relevant requirements. The aim of the study was to determine the sedative properties of the tinctures obtained from the American basil (Ocimum americanum L., Lamiaceae Martinov family) herb and to develop the standardization parameters for the promising herbal medicinal product. The open field test was used to evaluate the sedative effect of the prepared tinctures: (1) with the added of O. americanum essential oil (OATEs) and (2) without adding O. americanum essential oil (OAT). The standardization parameters for the OATEs were developed using validated High-Performance Thin Layer Chromatography (HPTLC) and High-Performance Liquid Chromatography (HPLC) methods. The HPTLC analysis was used for the chromatographic fingerprints of polyphenols and for identifying linalool in the OATEs. The HPLC analysis found the significant content of rosmarinic acid (RA) (0.26%) in the OATEs. In conclusion, the developed OATEs can be considered as the new herbal medicinal product with significant sedative properties.
Objective: The present study was designated to analyse the essential oils and tannins as important secondary metabolites of the aerial part of Satureja hortensis.
Methods:The chemical composition of S. hortensis herb was investigated using high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). The essential oil was obtained by hydrodistillation method.
Results:The essential oil yield in the aerial part of S. hortensis was 1.61%. GC-MS analysis of the essential oils identified the presence of 29 components. Carvacrol (76.16%), as the main component of essential oils, belongs to the group of aromatic compounds. Eight tannin components identified by HPLC and epigallocatechin (130.91х10 Ternopil, 46001, Ukraine Email: shanayda-mi@ukr.net -2 %) are prevalent among them.
Conclusion: S. hortensis was found to possess considerable amountKeywords: Satureja hortensis, Essential Oil, Tannins, HPLC, GC-MS.of phytoconstituents such as essential oils and tannins. The results of this research will help to study pharmacological properties of the investigated plant and to prevent possible adulteration with other plants.
