The researches are very less about the acetone extractives of rood wood from Cinnamomum camphora, a famous non-wood tree in China. Therefore, 550°C-based Py-GC/MS was used to analyze the high-grade resource recovering approaches of C. camphora root wood. The analytical result showed that the main components of the acetone extractives of C. camphora root wood by 550°C-based pyrolysis- GC/MS are as: Decanoic acid, 1,2,3-propanetriyl ester (16.720%), 4-Nitrophenyl laurate (9.104%), 1,3-Benzodioxole, 5-(2-propenyl)- (6.3744%), Bicyclo[2.2.1]heptan-2-one, 1,7,7-trimethyl-, (1R)- (5.646%), 2...
