Pine resources are rich in China totally including 10 genera and about 230 species around the world and 10 genera and about 120 species of which are in China 1 . Pinus massoniana belongs to the family of Pinaceae and is widely planted in China with the area reaching to 30 million Mu which is mainly applied to make artificial board, converted timber, rosin and paper-making. For example, the chemical constituents of oleo resin form high-quality Pinus massoniana are analyzed with GC 2 and the chemical components in wood and pulp/papermaking properties of 14 natural populations covering over the distribution range of Pinus massoniana are analyzed 3 and the reason why and how the impregnating and bleaching process is influenced by the solvent extractive was obtained 4 . However, Pine is not only a kind of forest plants with a wide range of distribution and also has great medicinal values. Modern pharmacological studies have shown Pinaceae plants extractives have antitumor, antivirus (HIV), antibacterial, antioxidant and enhance immune function 5,6 . Now a days, in order to develop the medicinal values of Pinaceae plants, the researchers at home and abroad only studied on the chemical components and pharmacological activity of a few species of Pinaceae.
