Abstract
Excessive exposure to ultraviolet (UV) radiation can cause various skin disorders, making skin protection such as sunscreen essential. Pineapple (Ananas comosus) peel is known to contain bioactive compounds with potential antioxidant and antibacterial properties. This study aimed to explore pineapple peel extract as an active ingredient in sunscreen lotion spray and to evaluate its physical characteristics, stability, and biological activities.
Pineapple peel extract was obtained through maceration using 96% ethanol, followed by phytochemical screening and determination of total phenolic and flavonoid contents. The extract was formulated into lotion spray preparations at concentrations of 20% (F1), 25% (F2), and 30% (F3), with a control formulation without extract (F0). Evaluations included physical characteristics, stability, Sun Protection Factor (SPF), antioxidant activity, antibacterial activity against Staphylococcus aureus, and a hedonic test involving 30 panelists.
The results showed that pineapple peel extract contained alkaloids, flavonoids, phenolics, saponins, and tannins, while steroids were absent. The total phenolic and flavonoid contents were 152.125 mg GAE/g and 37.96 mg QE/g, respectively. All formulations met the required physical characteristics and remained stable during storage. The SPF values of F1, F2, and F3 were 21.691, 24.087, and 26.120, respectively, indicating ultra protection. Antioxidant activity showed IC50 values of 865.28 ppm for F0, 82.64 ppm for F1, 31.26 ppm for F2, and 26.57 ppm for F3. Antibacterial activity produced inhibition zones of 13.592 mm, 14.555 mm, and 17.395 mm for F1, F2, and F3, respectively, which were classified as strong. The hedonic test indicated that all formulations were acceptable to the panelists. Therefore, pineapple peel extract has the potential to be used as an active ingredient in sunscreen lotion spray with antioxidant and antibacterial activities.
