Abstract

Body odor is a problem caused by the activity of microorganisms, one of which is the Pseudomonas aeruginosa bacteria by metabolizing sweat released by the body. The use of antiperspirant products is thought to reduce sweat production and bacterial decay . However, antiperspirants available in the market contain active chemicals that can cause irritation so it is necessary to use plant extracts as an alternative preparation of natural antiperspirant products. This study aims to determine the effectiveness of natural antiperspirant extracts of red shoot leaves (Syzygium myrtifolium Walp.) in inhibiting the growth of Pseudomonas aeruginosa bacteria that cause body odor. The method used is descriptive quantitative with parameters of simplicia and extract yield tests, extract characteristics, phytochemical screening, antibacterial effectiveness of extracts, physical quality tests of antiperspirants, antiperspirant effectiveness and Scanning Electron Microscope (SEM). The results of the study showed that the red shoot leaf extract meets the general standards of medicinal plant extracts and contains secondary metabolite compounds that are able to inhibit the growth of Pseudomonas aeruginosa bacteria with the formulated product producing suitable characteristics as an antiperspirant that is able to inhibit sweat production and the growth of Pseudomonas aeruginosa bacteria which is supported visually by Scanning Electron Microscope (SEM). Based on the results obtained, it is known that the natural antiperspirant red shoot leaf extract (Syzygium myrtifolium Walp.) has antibacterial effectiveness against Pseudomonas aeruginosa . Thus, the use of natural ingredients can be a solution to overcome the causes of body odor and reduce the use of conventional antiperspirant products that contain chemicals that are harmful to health.

Abstract

Deteriorating air quality during seasonal transitions contributes to the increased growth of pathogenic microorganisms, including Aspergillus fumigatus, which may lead to adverse health impacts. Synthetic antifungal agents may induce resistance and undesirable side effects, thereby promoting interest in safer natural alternatives. This study aimed to evaluate the antifungal effectiveness of a nasal spray formulated with kasturi orange (Citrus microcarpa) peel essential oil against A. fumigatus. The essential oil was extracted through steam distillation and tested at five concentrations to identify the most effective range, after which three concentrations exhibiting the strongest antifungal activity were formulated into a nasal spray. Antifungal effectiveness was assessed using the disc diffusion method, morphological alterations of fungal hyphae were observed using Scanning Electron Microscopy (SEM), and statistical analysis was performed using Analysis of Variance (ANOVA). The results showed that the nasal spray demonstrated significant antifungal activity (p < 0.05), with inhibition zone diameters of 12.8 mm, 16.1 mm, and 20.5 mm at essential oil concentrations of 10%, 20%, and 30%, respectively. Although the highest concentration produced the largest inhibition zone, excessively high essential oil levels do not necessarily improve antifungal performance and may trigger adaptive responses approaching resistance. SEM observations confirmed notable cellular damage, including hyphal lysis, cell wall thinning, and structural shrinkage following exposure to the nasal spray formulation. In conclusion, kasturi orange peel essential oil is effective when formulated as a nasal spray to inhibit A. fumigatus, with 20% identified as the most suitable concentration for further product development.

Abstract

Cutibacterium acnes bacteria are gram-positive anaerobic bacteria that play a role in the pathogenesis of Acne vulgaris (acne). The use of facemist containing natural active ingredients of patchouli leaf essential oil (Pogostemon cablin Benth) can be an alternative in inhibiting the growth of acne-causing bacteria. This study aims to determine the antibacterial activity of patchouli leaf essential oil facemist (Pogostemon cablin Benth) against Cutibacterium acnes bacteria. The method used in making essential oils by steam distillation, chemical compound analysis using Gas Chromatography-Mass Pectrometry (GC-MS) and antibacterial activity testing using the disc diffusion method then formulated into a facemist product and characterized. The results of the study showed that patchouli leaf essential oil had met the standard requirements and contained several of the highest chemical compound components, namely Patchouli alcohol (15.71% and 10.16%), Delta-Guaiene (CAS) (7.14%), Azulene, 1,2,3,4,5,6,7,8-Octahydro-1 (6.48%), 2-Butynyl-5-Hydroxy-3-Oxo-4-Hexanoic Acid Delta-Lactone (5.89%) and 1,1,4,7-Tetramethyldecahydro-1H-Cyclopropa[E] Azulene-4-Ol (5.17%) and the presence of antibacterial activity against Cutibacterium acnes bacteria with concentrations of 10%, 20%, 30%, 40% and 50% with inhibition zone diameters of 11.18 mm, 17.66 mm, 22.36 mm, 23.10 mm and 24.76 mm and the diameter of the antibacterial facemist inhibition zone with concentrations of 20% and 30% obtained results of 20.93 mm and 23.76 mm, then the facemist preparation showed characterization that was in accordance with the product's standard requirements. Based on the test results, it is known that the antibacterial face mist made from patchouli leaf essential oil has the ability to inhibit Cutibacterium acnes bacteria.
