缅甸卡西亚松松脂的化学组成

Chemical Constitution of Pinus kesiya Oleoresin from Burma

采用GC-MS联用技术对产自缅甸的卡西亚松松脂化学成分进行了分析和鉴定。鉴定出24种主要化合物,占总量的94.4%,其中单萜类5种,占41.39%,倍半萜类5种,占11.28%,二萜类14种,占41.73%。与我国云南地区生产的思茅松松脂比较,单萜和二萜类的主要化学成分组成差别不大,含量相近;倍半萜的主要化学成分差别较大,所含的β-依兰烯是卡西亚松松脂的化学组成特征物质。

Chemical constitution of Pinus kesiya oleoresin from Burma was analyzed by GC-MS. Twenty four compounds were separated and identified, which account for 94.4 % of the total content. There are 5 kinds of monoterpinene with content of 41.39 % , 5 kinds of sesquiterpinene with content of 11.28 %, and 14 kinds of diterpinene with content of 41.73 %. Compared with oleoresin of P. kesiya vat. langbianensis （ A. Chev. ） Gaussen from Yunnan of China, the main components and contents of monoterpinenes and diterpinenes were similar, but the chemical components and contents of sesquiterpinenes were different, and β-ylangene is a characteristic component in P. kesiyct oleoresin from Burma.
