Abstract

Indonesia is known for having abundant biological riches and many plants that can be used as medicine. One of the medicinal plants that is often used by Indonesian people is Jatropha curcas leaves. Jatropha plants are currently used as traditional medicine to treat wounds. One common medication used for cuts is povidone iodine which is effective against bacterial infections. However, povidone iodine also has side effects such as irritation, toxic reactions and burning skin. Jatropha leaves have strong antioxidant activity, so it is necessary to innovate in wound treatment using natural ingredients in the form of gel preparations. The gel preparation was chosen because it is practical, not sticky, easily absorbed by the skin, and works directly on wound tissue. The aim of this study was to assess how well a gel made from ethanol extract of jatropha leaves accelerates the healing of cut wounds in white mice. Jatropha curcas leaves were extracted using the maceration method using 96% ethanol as the solvent. Gel stability testing was carried out organoleptically, homogeneity test and spreadability test. Jatropha leaf extract gel was tested on mice that had been given incisions 1.4 cm long with formulations of 10%, 15% and 20% jatropha leaf extract concentrations. Observations were carried out for seven days. Research findings showed that giving white rats gel containing jatropha leaf extract significantly accelerated their ability to repair wounds

Abstract

Acne is a common dermatological condition caused by the bacterial infection of Propionibacterium acnes, leading to skin inflammation. Red galangal (Alpinia purpurata K. Schum) is known to exhibit antibacterial activity due to its essential oil content, flavonoids, and alkaloids. This study aims to formulate and evaluate the antibacterial activity of a gel preparation based on red galangal rhizome essential oil against Propionibacterium acnes. The research follows a laboratory experimental design, including the extraction of red galangal rhizome essential oil via maceration, formulation of the gel, and evaluation of its physical properties, such as pH, homogeneity, spreadability, and antibacterial activity using the disc diffusion method. The results demonstrated that the gel formulation met the required physicochemical standards, with a pH ranging from 6.4 to 6.8, good homogeneity, and an optimal spreadability of 5–7 cm. The antibacterial test revealed a significant inhibitory effect against Propionibacterium acnes, with an inhibition zone of up to 11.24 mm at a 15% concentration. These findings suggest that red galangal rhizome essential oil possesses strong antibacterial potential, making it a promising candidate for natural topical acne treatment. In conclusion, the red galangal essential oil gel exhibits favorable antibacterial activity against Propionibacterium acnes and has potential as an alternative acne treatment. Further studies are necessary to enhance the stability and efficacy of the formulation for optimal clinical applications.
