Phenolic and carotenoid composition of Rhododendron luteum Sweet and Ferula communis L. subsp. communis flowers

The biologically important potential of polyphenols and carotenoids from plants motivates the exploration new natural sources medicinal uses for these chemicals. Plants with colorful flowers are used not only benefits bioactive compounds but also smart textile materials as colorants. In this study, quantification phenolic in Rhododendron luteum Sweet Ferula communis L. subsp. were determined. analysed first time Türkiye. While catechin (297.36±3.42 µg/g), 4-OH benzoic acid (179.28±2.87 µg/g) salicylic (178.98±2.42 found to be relatively higher R. compared other compounds, amounts rutin (335.95±4.32 ferulic (367.10±4.11 F. flowers. On hand, lutein β-carotene detected both species, whereas astaxanthin (4.46±0.21 was luteum. This phytochemical information may proper utilization a variety possible commercial applications.
