WEN Fu-ji1, LI Jian-xiu1, WANG Wen-tao2(1.School of Chemistry and Chemical Engineering,Yancheng Teachers'College,Yancheng224002,China;2.Tianjin Polytechnical University,Tianjin 300160,China)  
Essential oil was extracted from pine needles and its compositions were determined by GC-MS.Ammonia deodorization experiment of extracted essential oil was done and 24 organic compounds in the essential oil were identified.Amount of monoterpene,sesquiterpene and oxygenated terpene in the essential oil was 59.24%,28.39% and 6.53% respectively.At room temperature,with mole ratio of essential oils to ammonia was greater in airtight containers,the deodorization rate was higher.While using ethanol as solvent,deodorization effect was more distinct.When using pure essential oil as deodorant and mole ratio of essential oils to ammonia of 12,deodorization rate can reach 100%.When using ethanol solution of essential oil as deodorant and mole ratio of essential oils to ammonia of 8,the deodorization rate can reach 100%.
