Abstract

Arogo (Premna serratifolia) is one of the plants that has the potential as a traditional medicinal plant to treat various diseases. The purpose of this study was to analyze the levels of alkaloids and tannins in arogo leaf extract. Arogo leaves were extracted by the meseration method using 96% ethanol as solvent and the extract was evaporated using a rotary evaporator at a temperature of 40&#8451-. Identification of alkaloids in the extract using Meyer and Dragendrof reagents and identification of tannins using FeCl3. Analysis of alkaloid and tannin levels was carried out using UV Vis spectrophotometer method at a wavelength of 273 nm for alkaloid content and a wavelength of 765 nm for tannin content. The results showed that positive arogo leaves contain alkaloids and tannins. The results of the analysis of the alkaloid content of arogo leaf extract were 0,962% and the tannin content analysis was 11,933%.
