Sage (Salvia officinalis) contains various active compounds, including flavonoids and terpenes. In this study, the terpenes content, including camphor, borneol, and eucalyptol, was analyzed. Both subcritical water and conventional solvent extraction methods were used. Using subcritical water extraction, the optimal extraction conditions were determined based on temperature and time to selectively extract the desired components from the sage. These optimal extraction conditions were as follows: camphor (130°C for 5 min, 2.73±0.39 mg/g), borneol (130°C for 5 min, 0.72±0.07 mg/g), and eucalyptol (150°C for 5 min, 0.51±0.03 mg/g). A comparison of extracts obtained via subcritical water extraction technology and various solvents revealed that the extracts obtained using subcritical water extraction had higher levels of all three components. This indicates that subcritical water extraction is more efficient and faster than traditional solvent extraction methods. Moreover, these results suggest that subcritical water extraction technology has the potential to be applied as an eco-friendly alternative to traditional extraction methods for obtaining active compounds like terpenoids.
