Elettariopsis curtisil, a medicinal plant from the Zingiberacee family, also known as ‘pokok pepijat’ due to its strong bed-bug odor when its leaves and roots are crushed. It has been chosen for its ability to dissolve bioactive compounds, safety, and biodegradability. Brucea Amarissiima, on the other hand, is a type of herb-type plant that is nutritious and easy to grow in the area around the house. This plant, also called ‘lada pahit’ or ‘embalau’ is a type of shrub from the Simaroubaceae family. The plant contains anti cancer compounds, thus we conducted advanced spectroscopic techniques, Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) to analyze the functional groups of these compounds. The results showed the presence of important bioactive compounds like alkaloids, flavonoids, and terpenoids, which have potential health benefits such as anti cancer, neuroprotective, cardioprotective, hepatoprotective and anti-inflammatory. In addition, we incorporated the saponification process using extracted oil from Elettariopsis curtisii and Brucea amarissima. Saponification process is a chemical reaction that converts oils into soap and glycerol, playing a key role in hygiene by helping to remove bacteria. This process not only enhances the practical applications of the extracted compounds but also demonstrates the potential of these plants in natural soap production. This research enhances our understanding of the chemical composition of these plants and supports future studies on their medicinal and hygienic applications.en-USATR-FTIRsoapsaponificationchemical compositionfunctional grouptext::conference output::conference proceedings::conference paper157162
