Item Developed validation for simultaneous determination of three Di-caffeoylquinic acid derivatives from the Leaf of Eribotrya japonica Lindl. by HPLC-DAD(Sociedade Brasileira de Ciência e Tecnologia de Alimentos, 2021-08-13) Seon, Ho-Young; Kim, Hyun-Hee; Yim, Soon-HoThe aim of this study was to developed HPLC simultaneous analysis method for the determination of Caffeoylquinic acid isolated from the leaf of Eribotrya japonica Lindl. extract. The phenolic compounds in E. japonica leaves were isolated and identified by HPLC, NMR, Mass etc. The quantitative analysis was carried out HPLC-DAD using C18 column with gradient elution of water and acetonitrile at 280 nM for 60 min. The method was successfully validated by specificity, LOD (linearity, limit of detection), LOQ (limit of quantification), precision and recovery. The three phenolic compounds were isolated from E. japonica leaves including 5-Caffeoylquinic acid (5-CQA), 4-Caffeoylquinic acid (4-CQA) and 3-Caffeoylquinic acid (3-CQA). In a quantitative analysis of three phenolic compounds were 3-CQA 7.82-14.48 µg/mL, 4-CQA 3.75-12.58 µg/mL and 5-CQA 3.60-7.82 µg/mL using the standard chemicals, respectively. The developed HPLC validation method would be applicable for simultaneous quantitative analysis of phenolic compounds in E. japonica leaves extracts.
