Summary
Finally, quercetin and abscisic acid were quantified to complete the data by HPLC-DAD.
Usefulness & Problems
Why this is useful
HPLC-DAD was used to quantify quercetin and abscisic acid in the dried Juglans regia extract. In this paper it serves as a chemical validation method rather than a biological assay.; quantifying selected compounds in the extract

Published Workflows
Objective: Evaluate the anti-inflammatory potential of Juglans regia fresh fruit extract in acute and chronic inflammatory states in vivo and complement the in vivo findings with in silico target-binding analysis and targeted chemical quantification.
Why it works: The workflow combines organism-level anti-inflammatory readouts with in silico binding hypotheses and targeted quantification of named constituents to connect observed activity with candidate compounds and targets.

Stages
- 1.In vivo anti-inflammatory assay evaluation(functional_characterization)
This stage tests whether the extract shows anti-inflammatory activity in acute and chronic inflammatory states in vivo.
Selection: Measure anti-inflammatory and pain-related responses of the extract in zymosan-induced edema, zymosan-induced thermal hyperalgesia, and formalin assays.
- 2.In silico docking analysis(secondary_characterization)
This stage provides candidate mechanistic support for the observed anti-inflammatory activity by identifying compounds with favorable docking to selected targets.
Selection: Assess binding of named compounds to AChE, BChE, and glucocorticoid receptor by docking.
- 3.Targeted compound quantification by HPLC-DAD(confirmatory_validation)
This stage completes the dataset by confirming the presence and abundance of selected compounds highlighted in the study.
Selection: Quantify quercetin and abscisic acid in the dried extract by HPLC-DAD.
