Abstract:
This experimental research aimed to investigate the extract from jackfruit seeds, along with the characterization of their chemical properties, biological activities, formulation development, and evaluation of product stability. The extraction process yielded a semi-solid dark brown extract. The percentage of yield was 6.39±0.32 of dry plant weight. ATR-FTIR analysis revealed characteristic absorption peaks corresponding to hydroxyl (-OH), C-H stretching, and glycosidic (C-O-C) linkages, which are indicative of polysaccharide structures.
Notably, the extract demonstrated a high polysaccharide purity. Total polysaccharide content, determined by the Phenol-Sulfuric acid assay, was 331.71±6.06 mg glucose equivalent/gram of extract. Reducing sugar content, assessed using the DNS method, was 259.23±1.30 mg reducing sugar/gram of extract. Non-reducing sugars were calculated to be 72.48±7.36 mg glucose equivalent/gram of extract, indicating the presence of oligosaccharides or complex polysaccharides with potential prebiotic activity.
Antioxidant activity evaluated by the DPPH radical scavenging assay demonstrated an IC50 value of 3.90±0.18 µg/mL, which is lower than that of the standard antioxidant Trolox (IC50 value of 4.60±0.42 µg/mL), highlighting potent antioxidant potential. Furthermore, a topical formulation containing the extract was developed and subjected to accelerated stability testing. The formulation showed slight changes in color, odor, pH, and viscosity, indicating the need for further optimization before application in natural cosmetic products.
