Abstract

Red lip (Syzygium myrtifolium Walp., Myrtaceae family) is an ornamental plant that is popular in Indonesia so that its existence easily found on the edge of the road and in the yard. Red lip contained phenolic compound. The purpose of this study was to comparized of total phenolic content of the young and old leaves red lip. Red lip were prepared into simplicia powder and extract, like traditional drugs in general. Simplicia was obtained from the drying process, while the extract was obtained from the maceration process with 96% ethanol. Each of the simplicia and extracts was determined by its phenolic content using the Folin-ciocalteu method. Folin-ciocalteu which reacted with phenolic compounds will form a blue complex. The blue complex was read on a UV-Vis spectrophotometer, then the results of the analysis data are tested statistically by the independent t-test method. The results showed that the average total phenolic content of young and old leaves simplicia were 7.22% and 8.20%, while the total phenolic content of young leaf extracts and old leaves were respectively 41.57% and 46.11%. These results showed that there were significant differences simplicia and extract in total phenolic contents between young leaves and old leaves with red lip. Keywords: red lip leaves, total phenolic, spectrophotometric uv-vis
