Phenolic constituent, antioxidative and tyrosinase inhibitory activity of Ornithogalum narbonense L. from Turkey: A phytochemical study
Scopus
Toplam 116 atıf DOI
This study examined the antioxidant and anti-tyrosinase activity and phenolic profiles of three extracts (ethyl acetate, methanol and water) obtained from different anatomical parts (bulb, stem and seed) of Ornithogalum narbonense. Antioxidant activity of the extracts was evaluated using DPPH*, ABTS+*, FRAP, CUPRAC, metal chelating and phosphomolybdenum assays. Tyrosinase inhibitory activity was measured using the modified dopachrome method with l-DOPA as the substrate. Phenolic content of the extracts varied according to plant part and extraction solvent and included HPLC-DAD, epicatechin, rutin, ferulic, protocateuchic p-hydroxybenzoic, chlorogenic, caffeic, benzoic and rosmarinic acids. The ethyl acetate extract of O. narbonense bulb samples demonstrated the most antioxidant and anti-tyrosinase activity and had the highest phenolic content. All other extracts showed moderate antioxidant and anti-tyrosinase activity. O. narbonense extracts, especially ethanol extract of O. narbonense bulbs, may have dietary and medicinal applications.

Swertia species are common ingredients in numerous herbal remedies. It is also used to treat a wide range of illnesses and possess diverse therapeutic activities. The aim of the study is to elucidate the comprehensive metabolomics profile of Swertia chirayita and the role of various extraction methods in the phytochemical compositions of the extracts of S. chirayita, and their antioxidant and enzyme inhibitory activities. Extraction of the stems, leaves, and flowering tops of S. chirayita was performed by maceration, infusion, and soxhlation using methanol and water as solvent. Extracts were subjected to phytochemical profiling by a liquid-chromatographic system. Antioxidant and enzyme inhibitory activity was carried out. The metabolomics profiling showed that a diverse range of specialized metabolites were present in the stems and leaves & flowering tops of the plant. All the extracts showed substantial antioxidant and enzyme inhibitory activities further confirmed by molecular docking studies. This study appraised the use of S. chirayita aerial parts as a potential antioxidant and its therapeutic application in various chronic illnesses including Alzheimer's disease, diabetes, and other skin-related disorders.
