Study on chemical constituents of oleoresin from Pinus msssoniana in Guangxi

Determination of different ages,different diameter and fertilization of the chemical composition of pine resin,analysis and comparison of the treatment difference between the components were carried out.The results show that the main components of the resin were basically identical each other,only the contents of composition were slightly different.The oil content increased with the increase of age and diameter.The oil contents of No.2,No.3,No.4 and No.16 fertilization were higher than the control's.α-pinene content of turpentine pine in all treatments were very high.
