Espresso machine is proven to be effective to extract compound from herbal plants in small scale. Particle size is one of critical parameters affecting amount of bioactive compound extracted from the plants. Therefore, in this study, a novel and economical pressurized liquid extraction method based on a hard caps espresso machine has been developed. Cymbopogon nardus powder with various particle size (mesh sizes 40/60, 60/80 and 100/120) were extracted with 40mL of water for 12-40 seconds using hard caps espresso machine. Geraniol content in the obtained extracts were then determined by gas chromatography paired with tandem mass spectrometry (GC-MS). This study showed that geraniol extracted from C. nardus powder with mesh sizes 40/60, 60/80 and 100/120 were 37.4; 44.7 and 23.5mg/g, respectively. The highest geraniol content was found in extract from mesh 60/80 powder. The result showed that particle size indeed affect concentration of bioactive extracted from herbal plants. The developed method proved to be fast, efficient and reliable. Further study should be performed to find optimum parameters in extraction process using espresso machine.
