Abstract
Volatile compounds in Pinus densiflora were extracted with Likens-Nickerson apparatus for three hours, and were separated and identified by gas chromatography(GC) and mass selective detector(MSD). Twenty six compounds were isolated from Pinus densiflora, identified by GC-MSD and twelve compounds were confirmed by matching retention times of the pure comounds. The main valatile compounds were terpenoids such as limonene(36.2%), $\beta$-pinene(16.9%), $\beta$-myrcene(12.6%) and $\alpha$-pinene(10.9%), and the total amount of these main compounds was 367.9$\mu\textrm{g}$ per 1g of pine twigs.
