摘要：
A sawdust of Sugi (Cryptomeria japonica D. Don) wood was treated under conditions of high steam pressures (2.75 approximately 2.94 MPa) at 230-degrees-C for 5 approximately 12 min and an explosive operation. The explosion products from the heart- and sap-wood were washed with water and extracted with hot benzene in order to remove a lignin-like component. The explosion treatment increased the benzene-soluble fraction as well as the methanol extracts. From the benzene-soluble fraction, vanillin 1, coniferyl aldehyde 2, and unidentified phenolic compounds were isolated along with sandaracopimaric acid 3, sandaracopimarinal 4, sandaracopimarinol 5, ferruginol 6, and beta-sitosterol.
