Chromatographic Profiles of the main Secondary Metabolites in the Monarda fistulosa L. Aerial Part
2021
Two different methods of chromatographic analysis have been used in this study for the phytochemical evaluation of main secondary metabolites in the aerial part of bee balm (Monarda fistulosa L.) as the non-officinal medicinal plant of the Lamiaceae Martinov family. The high performance thin layer chromatography (HPTLC) fingerprinting method was developed for the qualitative analyses of phenolic and non-polar compounds in the bee balm herb after its maceration in the solvents of different polarity. Such polyphenols as rosmarinic, caffeic and chlorogenic acids were authentically identified in the methanol extract of herb using HPTLC. Aromatic monoterpenoid thymol was identified by the HPTLC …
Antioxidant activity of essential oils obtained from aerial part of some Lamiaceae species
2018
Introduction: Essential oils are the perspective source of natural antioxidants because some synthetic antioxidants are now suspected to be potentially harmful to human health. As free radicals can cause inflammatory diseases, cancer, atherosclerosis, and aging, antioxidants can inhibit oxidative chain reactions. Essential oils have a wide range of pharmacological effects as they are multicomponent mixtures of chemical compounds, mainly terpenoids and aromatic components. Materials and Methods: The antioxidant activity of essential oils obtained from aerial parts of Ocimum americanum, Lophanthus anisatus, Monarda fistulosa, and Satureja hortensis (Lamiaceae) has been evaluated spectrophotom…
Polyphenols and Pharmacological Screening of a Monarda fistulosa L. dry Extract Based on a Hydrodistilled Residue By-Product
2021
This study aimed to determine the composition and content of polyphenols in the dry extract obtained from the hydrodistilled residue by-product of the wild bergamot (Monarda fistulosa L., Lamiaceae Martinov family) herb (MFDE) and to evaluate its safety and pharmacological properties. The total phenolic content (TPC) in the MFDE was 120.64 mg GAE/g. The high-performance liquid chromatography (HPLC) analysis showed the presence of a plethora of phenolic compounds, including hydroxycinnamic acids and flavone derivatives in the MFDE, with rosmarinic acid and luteolin-7-O-glucoside being the main components. With an IC50 value of 0.285 mg/mL, it was found to be a strong DPPH radical scavenger. …
