Abstract

Commercial antiperspirant products commonly incorporate synthetic compounds, several of which have raised concerns due to their potential carcinogenicity. Moreover, the inclusion of natural antibacterial agents in these formulations remains limited. Hibiscus sabdariffa L. (Rosella), a plant rich in bioactive secondary metabolites, offers a promising natural alternative. This study aimed to evaluate the antibacterial efficacy of rosella-based antiperspirant formulations, particularly against Staphylococcus epidermidis, a key contributor to body odor. Three formulations (F1, F2, and F3) were developed and assessed based on several parameters: pH, organoleptic properties, homogeneity, spreadability, adhesiveness, and antibacterial activity against Staphylococcus epidermidis. The results demonstrated that the antiperspirant preparations complied with standard evaluation criteria. Furthermore, the antibacterial assay outcomes yielded statistically significant differences (p < 0.05) in the mean diameter of the inhibition zones, indicating that H. sabdariffa L. exhibited measurable antibacterial activity against S. epidermidis. These findings support the potential application of Rosella extract in developing natural and efficacious anti-perspirant products.

Abstract

Chili peppers are acknowledged as one of the fruits endowed with a notable vitamin C content, a crucial nutrient integral to various physiological processes. These include collagen synthesis, bone and tooth formation, wound healing, and bolstering the immune system's defense against infections. Vitamin C, as a water-soluble compound, is susceptible to degradation when exposed to atmospheric conditions. Hence, careful preservation of chili peppers is imperative to maintain their vitamin C levels. The primary objective of this study is to discern the concentrations of vitamin C within three distinct stages of chili pepper ripeness: young, semi-ripe, and fully ripe. The methodology employed in this investigation entails UV-Vis Spectrophotometry, with a maximal wavelength for vitamin C quantification established at 265 nm. This approach yielded absorbance values of 0.696, 0.564, and 0.478 for the respective stages. Quantitative analysis reveals that the vitamin C concentrations in young, semi-ripe, and fully ripe chili peppers are 8.1397 ppm, 5.9559 ppm, and 4.5313 ppm, respectively. These findings unequivocally demonstrate that vitamin C content is significantly higher in young chili peppers when compared to their semi-ripe and fully ripe counterparts. The docking results for capsaicin ligands yielded Gibbs energy (?G), Ki and IC50 value -6.14 kkal/mol, 31.34 µm and 19.143 ppm, respectively. The result indicate that capsaicin exhibited good interaction to catalytic site of glycogen phosphorylase which could serve as a potential antidiabetic agent.
