Abstract
The recent global pandemic of the COVID-19 infection has caused significant impacts on the improvement of living environments. When utilizing Japanese cedar (Cryptomeria japonica) as building materials (such as interior finishing materials or structural materials), various beneficial effects are known to be exhibited based on the physical and chemical properties of the wood. However, existing Japanese Agricultural Standards (JAS) pertaining to C. japonica have primarily focused on regulating the quality of wood surfaces and preservation treatments, lacking specific methods for analyzing the terpene content, which is essential when discussing the wood's good functionalities for human such as enhancing immune system function and promoting physiological relaxation. Therefore, we positioned the standardization of analytical methods for functional components derived from C. japonica as an effective means to enhance the added value. In this study, we established a JAS-compliant analytical method for functional component analysis of C. japonica wood using gas chromatography-mass spectrometry.
