【 摘 要 】

References(19)Cryptomeria japonica bark was extracted using the hot compressed method, at temperatures higher than 373 K in different solvents. The yields of the extracts were 0.8–3.6%, under conventional extraction at ambient pressure. When the hot compressed method was used for extraction, however, the yields increased (1.2–9.6%). Based on the GC-MS analysis, the main components of the extracts were terpenoids such as ferruginol 1, 6,7-dehydroferruginol 2, and phyllocladanol 3. This study demonstrates that terpenoids in bark can be extracted using the hot compressed method.
