The physicochemical properties of Z. mauritiana leaves and fruit were measured based on their pH value, total acidity (TA) and total soluble solid content (TSS) while antioxidant capacity was analyzed using TPC, TFC, FRAP and DPPH assays. Based on the results, leaves showed the highest percentage of ash (9.06%) and crude protein (14.59%) while the moisture content (88.32%) was found the highest in fruit. The crude fiber (48.12%), fat (1.89%), carbohydrate (63.24%) and energy (411.61 kJ) were the highest in the seed. The results also showed that Z. mauritiana fruit had a higher value of TSS (11.70°Brix) and TA (0.32%) than the leaves while the pH of the leaves (5.47) was higher than fruit (4.77). The phytochemical compound of squalene (46.69%) in leaves, 5-hydroxymethylfurfural (35.04%) in fruit and conipheryl alcohol (21.45%) in seed were the major compounds found using GC-MS analysis. The antioxidant capacity of Z. mauritiana in different solvent extracts showed that the highest TPC, TFC and FRAP value was found in leaves water extract (287.71 mgGAE/g), in fruit water extracts (119.75 mgQAE/g) and leaves acetone extract (10.06 mgFe/g) respectively. While the strongest free radical scavenging activity against DPPH was shown in the leaves water extract (4.02 μg/ml). According to principal component analysis (PCA), flavonoid compound has shown a significant positive correlation with ferric reducing power by 0.760 while the extracts can be classified into three distinctive groups of potential phenolic, flavonoid and weak scavenging activity against DPPH.

description Nowadays, researchers around the globe are extensively searching for potential safe alternative drugs and antioxidant. The need for this alternative natural resource is due to the harmful side effects of current commercial synthetic drugs and antioxidant.
