Abstract

Jackfruit seeds (Artocarpus heterophyllus L.) contain secondary metabolites—such as flavonoids, tannins, saponins, alkaloids, and steroids/terpenoids—that possess potential as natural antioxidants. This study aimed to evaluate the effect of adding jackfruit seed ethanolic extract on the physical characteristics and antioxidant activity of cream formulations. Creams were formulated with extract concentrations of 0%, 2.5%, 5%, 7.5%, and 10%. Evaluations included phytochemical screening, organoleptic assessment, homogeneity, pH, spreadability, viscosity, irritation testing, and antioxidant activity analysis using the DPPH method. Phytochemical screening confirmed the presence of flavonoids, alkaloids, saponins, tannins, and steroids/terpenoids in the extract. All formulations produced homogeneous, non-irritating creams with pH, ​​spreadability, and viscosity values ​​that met the physical quality standards for topical preparations. Antioxidant activity increased with higher extract concentrations, evidenced by a decrease in IC50 values ​​from 101.13 µg/mL (FI) to 47.84 µg/mL (FV). Based on antioxidant activity classification, formula FV (10%) fell into the very strong category (IC50 < 50 µg/mL), while the other formulas ranged from moderate to strong. The results demonstrate that the addition of jackfruit seed ethanolic extract enhances antioxidant activity without compromising optimal physical quality, as it achieves a balance between antioxidant efficacy and physical characteristics that meet required standards.

Abstract

Balakka (Phyllanthus emblica L) is a wild plant, commonly used as a cooking spice called holat. The stem of balakka is believed to contain alkaloids, flavonoids, and tannins that have antibacterial properties. Most previous studies have focused on the fruit and leaves of balakka. On the other hand, Staphylococcus epidermidis bacteria are normal flora on human skin that cause infections. The increasing resistance of these bacteria to antibiotics makes it important to find alternative natural antibacterial agents. The purpose of this study was to examine the antibacterial activity of balakka stem extract and cream against Staphylococcus epidermidis bacteria and to evaluate the physical quality of the cream. This study used experimental methodology. The maceration method used ethanol p.a. on 100 g of balakka stem simplisia. The stages included phytochemical screening, cream formulation with concentrations of 1%, 2%, and 3%, and physical quality tests (organoleptic, homogeneity, emulsion type, pH, viscosity, stability, and irritation). Antibacterial tests were carried out using the agar well diffusion method on extracts and cream preparations. The results showed that 19.30 g of thick extract was obtained, which was positive for alkaloids, flavonoids, and tannins. The resulting cream met physical quality standards, was homogeneous, had an oil-in-water (O/W) emulsion type, a pH of 5.3–6.2, was stable, and did not cause irritation. The antibacterial activity of the extract showed inhibition zones of 14.5 mm (100 mg/ml), 11.5 mm (75 mg/ml), and 8.5 mm (50 mg/ml), while the cream showed 5.5 mm (1%), 7.5 mm (2%), and 9.5 mm (3%). Thus, ethanol extract of balakka stems has potential as an antibacterial agent and can be formulated into a safe cream that meets physical quality standards.
