Quantitative and Optimization of Phenolic Acid Extracted from Pomegranate by High Performance Liquid Chromatography (HPLC).

Objective: Pomegranate is scientifically known as Punica granatum L. which is a nutrient dense fruit rich in phytochemical compounds. Phenolic content is the main compound attribute for the most of the functional properties in pomegranate. The aim of this study is to quantify and optimize the composition of phenolic acids extracted from pomegranate extract by using High-performance Liquid Chromatography (HPLC). Method: The pomegranate extracted with three different methods by using two different solvents which is 50% ethanol and water. The methods were blended (aril+ seed), Soaking (aril+ seed) and soaking + squeezed manually. HPLC-PDA was used as equipment to quantify and optimize the phenolic acids extracted from pomegranate. Result: Validation method of HPLC was analysed according to the percentage of recovery, LOD, LOQ and coefficient correlation. Result showed that GA was detected in all sample from different method of extraction applied while CA compound not detected in any of extraction method applied. FA compound was only detected in blended method by 50% ethanol and water as solvent while EA compound was detected only in water extraction of all three methods applied. Conclusion: As a conclusion, according to the standard calibration data curve showed that this method proved to detect and quantify the targeted compounds. By comparing the data obtained from this study, it showed that water blended extract method is significantly higher content of targeted compound except for the CA compound. To the best of our knowledge, this sample can be a valuable source of antioxidant for better used in health benefits. [ABSTRACT FROM AUTHOR]
