Pomegranate is a nutrient dense fruit rich in phytochemical compounds, which phenolic acids are the main compounds that attribute for most of the functional properties of many fruits. The aim of this study was to characterize the pomegranate extract towards development of phenolic acids based on a non-opioid substitution therapy for in vivo and in vitro studies. Pomegranate was extracted using two different solvents with three different methods of extraction. The quantification of phenolic acids was performed using High-Performance Liquid Chromatography (HPLC). The level of Mμ Opioid Receptor (MOR) and cyclic Adenosine Monophosphate (cAMP) was analysed by using an in vitro assay to determine the morphine dependence. Meanwhile, the morphine withdrawal effect was investigated through an in vivo study by analysing the memory impairment of rats using Morris Water Maze (MWM) and by determining the level of Brain Derived Neurotropic Family (BDNF) and cAMP response element binding protein (CREB). The result reveals that the pomegranate extract with water had the highest phenolic acid composition of gallic acid, ferulic acid, and ellagic acid.
