Method development and validation of phloroglucinol and dieckol in Ecklonia cava using HPLC–DAD
The purpose of this study was to simultaneously analyze and validate phlorotannins, a group of functional compounds in Ecklonia cava, using HPLC–DAD. E. cava was profiled using UHPLC-Q-Orbitrap HRMS, and a total of six phlorotannin components were identified. Among these six compounds, phloroglucinol and dieckol were selected as marker components of E. cava, and a simultaneous analysis method using HPLC–DAD for phloroglucinol and dieckol was developed. Specificity, linearity, accuracy, precision, limit of detection (LOD), limit of quantification (LOQ), and matrix effect (ME) were verified using HPLC–DAD. These results complied with validation guidelines. The applicability of this simultaneous analysis method was confirmed by quantifying the contents of phloroglucinol and dieckol in E. cava samples (n = 10) purchased in Korea. This method can be used for quality control, such as standardization or determination of compounds in health functional foods containing E. cava extract.
期刊介绍：
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
