Abstract

The patikan kebo plant is used to cure respiratory infections, malaria, liver, hypertension, gastrointestinal, skin diseases, accelerate wound healing, antidotes, hepatitis, rheumatism and tumors. The purpose of this study was to determine the antifungal activity of patikan kebo. The research method was carried out experimentally with the paper disc diffusion method. The antifungal activity test of each concentration (1%, 2%, 3%, 4%, ketoconazole, DMSO) had respective values (7.14 mm, 7.67 mm, 8.51 mm, 8.80 mm, 26.81 mm, 0 mm). The content of secondary metabolites in the patikan kebo plant are saponins, tannins, alkaloids, steroids/triterpenoids and flavonoids. The patikan kebo plant has medium category antifungal potential.

Abstract

Typhoid fever is a major disease of death in the medical field caused by Salmonella typhi infection with symptoms including fever, mucosal lesions, vomiting, diarrhea, fluid loss, septicemia, and peritonitis. The use of natural plants to cure infectious diseases such as andaliman fruit. The aim of this study was to determine the antibacterial activity of Andaliman fruit extract on the growth of Salmonella typhi. Experimental research method. The Kirby-bauer method was used for the antibacterial test, the maceration method was used for extraction. The results of phytochemical compounds found flavonoids, tanins, saponins, tannins, alkaloids steroids, and triterpenoids in simplicia and andaliman fruit extracts. All extracts have the potential to inhibit the growth of Salmonella typhi, with the diameter of the inhibition zone consisting of 10.04 mm, 12.22 mm, 15.46 mm and 16.68 mm in the strong category. These doses are 10%, 30%, 50%, and 70%. The analysis shows the potential of Andaliman fruit extract as an antibiotic in the treatment of typhoid fever.

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

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%
