Abstract

Chromolaena odorata L. has bioactive compounds that can be used as raw medicine materials. Bioactive compounds from Chromolaena odorata L. are reported to have pharmacological and antibacterial properties. This study aims to  the antibacterial activity. The antibacterial activity testing used the agar diffusion method using paper discs with 25, 50, 75, 100, and 125 µg/disc extract concentrations. Based on the results obtained, the ethanol extract of Chromolaena odorata L. has antibacterial activity of S. aureus with inhibition zone diameters of 12.14, 11.99, 12.63, 12.62, and 13.85 mm.

Abstract

The use of cosmetics such as lipstick aims to improve the natural appearance of the lips and induce discoloration. A problem that is often worrying about today is the presence of prohibited dyes in lipstick preparations' main components. Rhodamine B is a synthetic dye prohibited in cosmetics, especially lipsticks. This research aims to analyze the Rhodamine B dye in lipsticks that do not have a distribution permit from BPOM circulating in the Beriman Tomohon market.The research method was Thin Layer Chromatography (TLC), followed by wavelength measurement on UV-Vis Spectrophotometry. The research population was all red lipstick preparations and 10 (ten) different lipsticks as a sample.Data analysis in this research is to find the RF value obtained from TLC then make a graph of the equation y = bx + a then look for the x value to measure the Rhodamine B content in lipstick. The results of this research were obtained from 1 (one) sample of lipstick label L(I) positive containing Rhodamine B. Visually, the lipstick of the L(I) label has a pink color and fluorescence orange when irradiated with 366nm UV, Rhodamine B has an Rf value of 0.85. In contrast, the L(I) sample has an Rf value of 0.84. Rhodamine B has a wavelength of 544nm, and the lipstick sample L(I) has an absorbance of 0.362 which has a Rhodamine B content of 0.4115%.

Abstract

Avocado seeds (Persea americana) have long been used in traditional medicine and are empirically believed to reduce fever. This study aimed to evaluate the antipyretic activity of an avocado seed infusion in male white rats (Rattus norvegicus) induced with peptone. The infusion was prepared using distilled water at 90 °C. The antipyretic test consisted of five groups: a negative control (Na-CMC), a positive control (paracetamol), and three treatment groups receiving avocado seed infusion at doses of 100, 200, and 300 mg/200 g body weight. Fever was induced by intramuscular injection of 5% peptone (1 mL/200 g body weight). Rectal temperature was recorded at 30-minute intervals for 3 hours. The results showed that all treatment doses reduced rectal temperature after 180 minutes. The greatest reduction was observed at a dose of 300 mg/200 g body weight, with a decrease of 2.16 °C, indicating that avocado seed infusion exhibits dose-dependent antipyretic activity.
