Qin Meng-hua; Chen Jia-xiang; Yu Jia-luan(South China University of Technology, Guangzhou, 510641)  
Acetone extractives in masson pine (Pinus massoniana lamb)groundwood pulp were isolated and analyzed through the employment of DEAE-Sephadex ion exchange chromatography and GC/MS.DEAE-Sephadex ion exchange chromatography fractionated the extractives into neutrals, weak acids and strong acids, and the neutrals were further separated into saponifiables and unsaponifiables through saponification.The chemical components of the weak acids, saponifiables and unsaponifiables in the extractives were analyzed by GC/MS technique and a series of compounds were identified.
