Comprehensive Qualitative and Quantitative Analysis of Flavonoids in Dandelion (

This study focuses on comprehensive qualitative and quantitative analysis of flavonoids in dandelion (. The research employs high-performance liquid chromatography (HPLC) techniques to address analytical challenges in the food safety field. Research Background and Significance Flavonoids are a diverse group of polyphenolic compounds widely distributed in the plant kingdom and recognized for their significant biological activities, including antioxidant, anti-inflammatory, and antimicrobial properties. Dandelion (Taraxacum officinale) is a common medicinal and edible plant known to contain a rich profile of flavonoids, which contribute to its therapeutic potential and nutritional value. Accurate qualitative and quantitative analysis of these flavonoids is essential for ensuring food safety, quality control, and efficacy of dandelion-based products. Despite the importance, challenges persist due to the complexity of plant matrices and structural similarity among flavonoid compounds. This study addresses these issues by developing and validating a robust high-performance liquid chromatography (HPLC) method, enabling comprehensive profiling of flavonoids in dandelion. This work is particularly significant in the food safety domain, where precise detection and quantification of bioactive compounds are critical for regulatory compliance and consumer protection. Experimental Design and Methodology The study employed advanced HPLC techniques tailored for the separation and quantification of dandelion flavonoids. Though the exact HPLC system details are not specified, the methodology likely involved reversed-phase chromatography using C18 stationary phases, which are well-suited for flavonoid analysis due to their hydrophobic interactions.
