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.

The US patented polyherbal formulation for the prevention and management of Type II diabetes and its vascular complications was used for the present study. The formulation consists of roots of Salacia species, leaves of Lagestroemia parviflora and fruit rind of Garcinia indica. The use of reversed phase C18 HPLC column was used and eluted with isocratic mobile phase of acetonitrile and phosphoric acid buffer solution enabled the efficient separation of chemical markers within 20min. Validation of the method was performed in order to demonstrate its selectivity, accuracy, precision, repeatability and recovery. All calibration curve shows good linear correlation coefficients (r2\>0.995) within tested ranges. Three markers in this polyherbal formulation were quantified were Mangiferin (1.53\% w/w), Ellagic acid (0.9655 w/w), Hydroxycitric acid (5.3\% w/w). Intra and inter day RSDs of retention times and peak areas were less than 3\%. The recoveries were between 95\% and 102.5\%. In conclusion a method has been developed for the simultaneous quantification of three markers in this polyherbal formulation. The established RP-HPLC method was simple, precise and accurate and can be used for the quality control of the raw materials as well as formulations.

Key words: Polyherbal formulation, Mangiferin, Ellagic acid, Hydroxycitric acid, RP-HPLC.
