Abstract

Chromolaena odorata (L.) is one of the plants known as weeds. Alkaloids, flavonoids, saponins, tannins, and glycosides are active chemicals found in Siam weed leaves. The study aimed to see if an ethanol extract of Siam weed leaves can be made into liquid soap and has antibacterial action against Staphylococcus aureus germs. The liquid soap of Siam weed (Chromolaena odorata L.) leaf ethanol extract at concentrations of 3%, 6%, and 9% was carried out experimentally in the laboratory, along with physical liquid soap evaluation tests such as organoleptic test, homogeneity test, pH test, foam height test, specific gravity test, test irritation, and hedonic test. Staphylococcus aureus bacteria were then tested. The assessment test criteria were met by making liquid soap preparations of ethanol extract of Siam weed leaves  at concentrations of 3%, 6%, and 9%. The color of the solid soap was brown - dark brown, and the texture was liquid with a lemon scent; the homogeneity test showed that all preparations were homogeneous; the pH test of the soap was 9.1 -9.7; the foam height test was 53-66 mm; the specific gravity test was 1-1.01 g/ml; and the irritation test revealed that all preparations had no reaction to redness, itching, and swelling on the skin. The hedonic test on skin revealed that all preparations obtained favorable evaluations from the panelists. The antibacterial activity of liquid soap against Staphylococcus aureus germs was F1 3.65 mm, F2 5.75mm, and F3 6.5mm. Based on the results of the Staphylococcus aureus test, it could be concluded that in the formula F1 (3% concentration), F2 (6% concentration) and F3 (9% concentration) had an inhibition zone.

Abstract

One of the plants that has the potential to be utilized as medicine is purple cabbage (Brassica oleracea Linn.). Commensal fungi like Candida albicans and Malassezia furfur can be found in the genitourinary tract, vagina, urethra, skin, fingers, and toes, among other places on the body. The purpose of: The study aimed to learn more about the antifungal properties of the ethanol extract of purple cabbage in preventing the growth of Malassezia furfur and Candida albicans. This study used an experimental design to examine the independent variables of the purple cabbage extract with various doses of the growth activity test of Candida albicans and Malassezia furfur, as well as their inhibition zones. Purple cabbage contains steroids, saponins, tannins, and flavonoid compounds. With concentrations of 10%, 20%, 30%, and positive control, the average diameter of the inhibitory zone for Candida albicans was 4.83 mm, 7.2mm, 8.75mm, and 6.21mm. The concentrations of Malassezia furfur at 10%, 20%, 30%, and the positive control were 4.61mm, 6.36mm, 8.83mm, and 6.15mm, respectively. As a negative control, DMSO failed to exhibit an inhibitory zone. Statistics revealed a substantial difference, indicating that the concentration had an impact on how the inhibition zone developed. The ethanol extract of purple cabbage has antifungal action, and the treatment with the 30% extract concentration forms the optimal concentration. It is advised that more research be done on the antifungal activity of purple cabbage extract against various kinds of fungus and that dosage forms be created for it.

Abstract

Health problems that occur today are diverse and varied, one of which is being overweight. This study focuses on the formulation of herbal extracts in conventional tablet preparations using Jati Belanda, Kumis Kucing, Meniran, Sirih, and Kunyit which have the potential as weight loss agents. Extraction is carried out using the maceration method, then the extract is made into conventional tablets with additional ingredients: magnesium stearate, talc, PVP, Avicel pH 102, and aerosil. Evaluation of physical properties such as uniformity of size, uniformity of weight, hardness, and disintegration time has been carried out. The results of the study showed that conventional tablet preparations from various spices with 3 different formulations were successful. However, the results of the tablet hardness test have not met existing standards. The danger is the lack of PVP (Polyvinylpyrrolidone) excipients in the granules which cause the tablets to become brittle. To improve the formulation, the addition of the moisturizing agent can be done.

Abstract

Bacterial infections produce diseases such as Escherichia coli diarrhea, which is a big issue in developing countries. Clove flower (Syzygium aromaticum), Cinnamon bark (Cinnamomum verum), and Star anise (Illicium verum) contain active ingredients such as alkaloids, saponins, flavonoids, polyphenols, tannins, glycosides, and volatile oils which have potential as antibacterial. This study aims to analyze the difference in the inhibition zone of the extracts of the three plants extracted with 96% ethanol solvent against Escherichia coli using the disc diffusion method with extract concentrations of 15%, 20%, and 25%, and compare them with thiamphenicol as a positive control with the same concentration. The results show that the extracts have antibacterial activity that increases with the increase in concentration, where 25% concentration give the largest zone of inhibition. The clove extract has the highest inhibition, followed by cinnamon and star anise, although thiamphenicol remained the most effective. These findings confirm the significant antibacterial potential of all three extracts with α = 0,000.
