Abstract: As the outer organ of the body, skin becomes the main target of environmental influences, particularly the UVB rays. Based on analysis of phytochemicals, red pomegranate peel extract contains antioxidants such as flavonoids, phenols, tannins, and vitamin C which are able to prevent increased skin melanin by inhibiting the actions of tyrosinase. This study was aimed to prove that application of 8% red pomegranate peel extract (Punica granatum) cream could prevent the increase of skin melanin in female guinea pigs (Cavia porcellus) exposed to UVB as well as to prove that the 8% red pomegranate peel extract cream was as effective as 4% hydroquinone cream in preventing increased skin melanin. This was a true experimental study using post test only control group design. Subjects were divided into three groups, with 10 guinea pigs each group. Group 1, the control group, was treated with UVB exposure and basic cream. Group 2 was treated with UVB exposure and 4% hydroquinone cream. Group 3 was treated with UVB and 8% red pomegranate peel extract cream. A total of 390 mJ/cm UVB dosage was given for 2 weeks. Histopahtologic slides were stained with Masson-Fontana. The amount of melanin area colored in black was evaluated by the percentage of pixel areas of melanin compared with pixel areas of all epidermal tissues. The results showed that the highest amount of melanin was in group 1 (18.13±4.76%), followed by group 3 (1.876±0.73%), and group 2 as the lowest (0.67±0.291%). There was a significant difference between control group and group 2 as s well as group 3 (P <0.05). There was no significant difference between group 2 and group 3 (P >0.05). Conclusion: Application of 8% red pomegranate peel extract (Punica granatum) cream could prevent the increase of skin melanin in guinea pigs (Cavia porcellus) exposed to UVB. The 8% red pomegranate peel extract cream was as effective as 4% hydroquinone cream in preventing increased skin melanin.Keywords: red pomegranate peel extract, melanin, skin, UVBAbstrak: Sebagai organ terluar dari tubuh, kulit menjadi target utama dari pengaruh lingkungan, terutama oleh sinar UVB.

ABSTRACT: Pomegranate (Punica granatum L.) contains a high concentration of antioxidant and phenolic compounds. Pomegranate peel extracts at different concentrations were used as natural antioxidant to increased the lipid stability of fresh Tuscan sausages, comparing with sodium erythorbate (SE). Peels were subjected to ultrasound-assisted aqueous extraction and lyophilization. The extract was previously characterized throught phenol and flavonoids determination. The Tuscan Sausages were prepared, and color, pH, peroxides, and thiobarbituric acid reactive substances were assessed at 1, 15, and 30 days of storage, at a mean temperature of 5 ± 1 ºC and under a 12-hour light cycle/day. Sausages containing 0.05 and 0.1% of peel extract showed results similar to sodium erythorbate in lipid peroxidation. Sausages treated with pomegranate peel extracts showed an adequate global acceptability level in the sensory analysis. Pomegranate peel extracts are; therefore, a promising natural alternative for maintaining the lipid stability of Tuscan sausages, promoting the protection of the meat and in addition, being able to bring beneficial of the pomegranate to the human health.

The inhibition effect of pomegranate peel extract (PPE) on the corrosion of mild steel in hydrochloric acid (HCl) solution was investigated. The polarization, mass loss, and electrochemical impendence techniques were used to evaluate the corrosion inhibition performance of the pomegranate peel extract. The results revealed that PPE acts as a corrosion inhibitor in HCl solution. The inhibition efficiency increased with the increase of extract concentration. The inhibition action was attributed to the adsorption of the chemical compounds present in the extract solution, on mild steel surface.
