Py-GC/MS technology was used to analyze the high-grade resource recovering approaches of C. camphora root wood at 350°C. The result showed that the chemical components of acetone extractives from C. camphora root wood are as: Benzene, 1, 2-dimethoxy-4-(2-propenyl)-(10.255%), Bicyclo[2.2.1]heptan-2-one, 1, 7, 7-trimethy1-, (1R)-(7.751%), p-menth-l-en-8-ol (5.765%), Phenol, 2, 6-dimethoxy-4-(2-propenyl)-(3.833%), 1, 6-Cyclodecadiene, l-methyl-5-methylene- 8-(1-methylethyl)-, [s-(E, E)]-(3.669%), D-Allose (3.265%), Acetic acid (2.784%), l(2H)-Naphthalenone, octahydro-8a-hydroxy-(2.719%), 1, 3...
