Concurrent HPLC detection of javamide‐I/‐II, caffeine, 3‐ O‐caffeoylquinic acid, 4‐O‐caffeoylquinic acid and 5‐O‐caffeoylquinic acid; their comparative quantification and disparity in ground and instant coffees

SEPARATION SCIENCE PLUS, 2019
Abstract Recent reports suggest that javamide‐I/‐II found in coffee contain anti‐inflammatory activity greater than 3‐O‐caffeoylquinic acid, 4‐O‐caffeoylquinic acid, 5‐O‐caffeoylquinic acid and caffeine. However, there is little information about javamide‐I/‐II amounts in coffee products, impossible to assess their biological activity.

Glucosylated caffeoylquinic acid derivatives from the flower buds of Lonicera japonica

Acta Pharmaceutica Sinica B, 2015
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 ...
