Three new glucosylated caffeoylquinic acid isomers (1-3), along with six known compounds, have been isolated from an aqueous extract of the flower buds of Lonicera japonica. Structures of the new compounds were determined by spectroscopic and chemical methods as (-)-4-O-(4-O-β-d-glucopyranosylcaffeoyl)quinic acid (1), (-)-3-O-(4-O-β-d-glucopyranosylcaffeoyl)quinic acid (2), and (-)-5-O-(4-O-β-d-glucopyranosylcaffeoyl)quinic acid (3), respectively. In the preliminary in vitro assays, two known co ...[more]
