Abstract

Red roselle (Hibiscus sabdariffa L.) is a plant that can be used by the community as traditional medicine. Rosella flower petals contains protein, fat, minerals, alkaloids, flavonoids, and tannins. Red rosella is effective in preventing vertigo, antihypertension, antidiabetic, anticancer, and antioxidants. Tannins are known as one of the active ingredients contained in the petals of red rosella flowers. Tannins are polyphenolic protein. This study aims to determine the levels of tannin in the extract of red rosella flower petals using permanganometry titration. The research method used was observational. This study used a sample of red roselle flower petals. The sample was tested qualitatively using FeCl3 1%. Analyzed quantitatively using permanganometry titration. The results showed that qualitatively the positive sample contained tannins which was marked by a change in color to dark blue dark. Quantitatively the sample was titrated with KMnO4, the tannin content in red roselle flower petals was 13,73 % b/b.

Abstract

During the Covid 19 pandemic, a handsanitizer product has emerged which functions as a hand washing disinfectant for the prevention of the Covid 19 virus. One of the ingredients that can be made handsanitizer gel is the mulberry plant (Morus alba L.) because it contains many flavonoids which act as antiseptics against bacteria. The research objective was to determine the handsanitizer gel formulation with the concentration of carbopol and propylenglycol which can produce good physical properties. The research design used an experiment, with the mulberry leaf preparation material macerated using 70% ethanol. Mulberry leaf ethanol extract (Morus alba L.) as the active substance and made 3 formulas with variations in the concentration of carbopol: propylenglycol formula I (0.5%: 15%), formula II (1.25%: 12.5%), formula III (2%: 10%). The three formulas were tested for physical properties and analyzed by ANOVA with a confidence level of 95%. The results showed that the handsanitizer gel formulation with carbopol increased viscosity and stickiness, while propylenglycol increased the dispersibility. The 1.25% formula: 12.5% ??produces the best physical properties, with a pH test of 6, a viscosity test of 150 dPas, a spreadability test of 6.5 cm, a sticky power test of 2.39 seconds and a protective power test without red stains.
