Abstract
This study aims to isolate and identify the secondary metabolites compound ethyl acetate : n-hexane (4: 6) fraction from Gulma siam leaves (Chromolaena odorata L.), which is derived from Enrekang regency, South Sulawesi, Indonesia. The stages of research include extraction, fractionation, purification and identification. Fractionation is done by flash column chromatography; purification by recrystallization and identification using color test, melting point, solubility, KLT and spectroscopic methods. Obtained compound in the form of white crystal with a melting point about 144-145oC, also react positively with Dragendorff and Wagner reagent that is marked by orange solution and brown precipitants which indicate the possibility of containing secondary metabolites compound that includes in alkaloid class. It is also supported by the presence of N-H absorption around 3329.14 nm; aliphatic C-H around 2916.37 nm; aromatic C-C around 1620.21 nm; C-N around 1357.89 nm and C-O around 1068.50 nm that is obtained on the IR spectrum.
