Background: Celery (Apium graveolens L.) contains the polyphenolic secondary metabolite group and exhibits various pharmacological activities. Celery is a rich source of potassium, an essential mineral that contributes to fluid balance regulation and may help reduce the risk of hypertension.
Objective: This study aimed to identify the presence of potassium and compare the total flavonoid content of various preparations of celery: in ethanolic extract, fresh plant infusion, dried plant infusion, and celery juice
Methods: Potassium was identified using color and flame tests. Total flavonoid content was determined by UV–Visible spectrophotometry and expressed as kuersetin equivalents (QE).
Results: Potassium was successfully identified in all tested samples, including ethanolic extract, fresh plant infusion, dried plant infusion, and celery juice, as indicated by the formation of rosette-shaped crystals in the color test and a characteristic violet flame in the flame test. The total flavonoid contents of the ethanolic extract, fresh plant infusion, dried plant infusion, and celery juice were 16.7240 ± 0.1898, 0.2662 ± 0.0015, 3.6000 ± 0.0090, and 0.0019 ± 0.0000 mg QE/g, respectively.
Conclusion: All celery preparations evaluated in this study contained potassium. Ethanol extract is more effective in recovering flavonoid compounds from Apium graveolens L. than infusion or juice preparation methods.
