Supercritical fluid extraction (SFE) is a green technology that is convenient to extract Pelargonium radula ( P . radula) leaves without leaving any negative impacts on the environment. It is an alternative approach to reduce the solvent residual problem during the extraction process. Therefore, this research was performed to compare the active ingredients extracted by SFE technique with the commercialized geranium essential oil in the market. Extraction of powdered P. radula leaves by supercritical carbon dioxide (SC-CO 2 ) was operated at constant pressure, temperature, and solvent flowrate which were 100 bar, 40 °C, and 24 mL/min, respectively. SC- CO 2 extraction on P. radula leaves result in 0.19 % of oil yield. By comparing extracted P. radula oil with the commercialized geranium essential oil, both oil consists of benzyl acetate, citronellol, geraniol, e-amyl cinnamaldehyde, isopropyl tetradecanoate, and isopropyl hexadecanoate.
