Abstract

A prevalent global infection that manifests frequently in Indonesia. An example of an infectious disease that is commonly encountered during adolescence is acne (Acne vulgaris). Antibiotics can be used to treat acne; however, their misuse can lead to the development of resistance; therefore, we are searching for inexpensive, readily available alternatives that are also secure. Mangosteen leaves (Garcinia mangostana L.) are one alternative to synthetic ingredients when it comes to the treatment of acne. Mangosteen leaves comprise xanthone derivative compounds that exhibit significant biological activity, including antioxidant, antibacterial, and antimicrobial properties. Therefore, this this study aimed to ascertain the inhibitory power of an ethanol extract derived from mangosteen leaves in order to determine its antibacterial activity against Staphylococcus epidermidis bacteria. Additionally, the compound content of the ethanol extract of mangosteen leaves was determined. The inhibition test was conducted by utilizing the paper disc technique, while the extraction method employed the maceration method. As indicated by the phytochemical screening test results, simplicia and ethanol extract of mangosteen leaves were found to contain steroids/triterpenoids, alkaloids, flavonoids, saponins, and tannins. The inhibition test outcomes against Staphylococcus epidermidis bacteria revealed the following: a diameter of 3.3 mm for bacteria at a concentration of 20%, 9.4 mm for bacteria at 40%, 10.4 mm for bacteria at 60%, 12.9 mm for bacteria at 80%, and 13.2 mm for bacteria at 100%

Abstract

Skin infections contribute to one of the most significant global health issues. Acne, blisters, and abscesses are examples of skin infections that can be induced by Propionibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis. Treatment can be attempted through the development of nanotechnology in the form of nanocellulose. Nanocellulose, an organic substance, can be produced through the conversion of coconut water waste and Acetobacter xylinum bacteria. Future applications of nanocellulose formulated with a blend of extracts derived from natural sources, including Patikan Kebo (Euphorbia hirta L.), are anticipated to include the treatment of wound dressings (patches). Determining the antibacterial potential of nanocellulose was the objective of this study. The experimental research technique is implemented in phases. The extraction process was conducted by means of maceration, while the parallel streak method was utilized for antibacterial testing. The findings of the study indicated that the mean zone of inhibition for each treatment variable was as follows: 0 mm, 15.1 mm, 23.53 mm, and 23.06 mm for nanocellulose (serving as the negative control), nanocellulose and 0.5% extract, 1% extract, 1.5% extract, and clindamycin, respectively. Conclusion: Antibacterial activity was observed in nanocellulose extracts containing 1% and 1.5%

Abstract

Essential oils, known as volatile oils or essential oils, are oils produced from plants and have the property of easily evaporating at room temperature without undergoing decomposition. The bay leaf plant (Syzygium polyanthum (Wight.) Walp.) is one of the plants that is very often used as an alternative medicine. There is evidence that bay leaves, which contain compounds such as niacin, fiber, tannin, and vitamin C, have the ability to lower serum triglyceride levels. This research aims to determine the essential oil content in bay leaves using the steam distillation method and its potential as an antibacterial. The results of the research show that bay leaves contain essential oils which have antibacterial properties against the bacteria Helicobater pylori and Bacillus cereus. Bay leaf essential oil (Syzygium polyanthum (Wight.) Walp) with varying concentrations of 10%, 30%, 50%, 70% and 100% showed the highest inhibitory zone diameter for Helicobater pylori bacteria, namely at a concentration of 100% with a diameter of 5, 25 mm and in Bacillus cereus bacteria with a diameter of 7.95 mm.

Abstract

Paracetamol is a medication that is safe for children to use to relieve pain and reduce fever, with minimal side effects. This medication is available in various forms, including syrup, which consists of a solution with a high sucrose content. Maximum Wavelength and Calibration Curve: In the study, the standard paracetamol was analyzed to determine that the obtained wavelength is at 246 nm. Several solutions with different concentrations (10, 15, 20, 25, and 30 ppm) were used to create a calibration curve, which shows the relationship between absorbance and concentration. Linear regression equation: Y = 0.0044x – 0.0166, R² = 0.9936. The absorbance of the syrup sample indicates a paracetamol concentration of approximately 24.23 ppm for sample X and 17.63 ppm for sample W, calculated using a calibration curve. Thus, the research shows an effective analytical method for determining the concentration of paracetamol in syrup preparations.

Abstract

Pathogenic bacteria have negative impacts if exposed to the human body for a certain period of time. It is necessary to inhibit bacterial growth from natural materials because they generally have non-toxic, environmentally friendly, and biodegradable properties. This study used Chinese betel leaf extract (Peperomia pellucida (L.) Kunth) as an antibacterial material against Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus. The results of the phytochemical screening analysis showed that there were secondary metabolites in the extract and simplicia such as tannins, alkaloids, and flavonoids. The antibacterial test pad with the largest concentration variation has a strong and very strong category on the three types of bacteria, namely against Staphylococcus epidermidis (diameter 19.9 mm) at a concentration of 5%, Staphylococcus aureus (diameter 22.92 mm) at a concentration of 7%, Propionibacterium acnes. (diameter 19.63 mm) at a concentration of 7%.
