The compositions of the mixtures of sesquiterpenoids, largely hydrocarbons that were found in the inner bark of the silver birch, Betula pendula Roth and the paper birch, Betulapapyrifera Marshall, grown in New Zealand were analyzed by SPME-GCMS. The major components of the volatile oil from the inner bark of B. pendula were trans alpha-bergamotene (31%) and alpha-santalene (19%). This composition was quite different from that of the oil from the branches, buds and leaves of the same species from Turkey, but was very similar to that of the oil from the bark of B. pubescens from Russia. The major components of the oil from the inner bark of B. papyrifera were trans alpha-bergamotene (18%), ar-curcumene (12%), E-beta-farnesene (12%), Z-beta-farnesene (10%) and cis-alpha-bergamotene (8%).
采用固相微萃取-气相色谱-质谱联用（SPME-GCMS）技术分析了生长在新西兰的欧洲白桦（Betula pendula Roth）和纸皮桦（Betulapapyrifera Marshall）内皮中倍半萜类混合物的组成，这些混合物主要是碳氢化合物。欧洲白桦内皮挥发油的主要成分是反式α-佛手柑油烯（31%）和α-檀香烯（19%）。这种成分与来自土耳其的同一物种的树枝、芽和叶中的油的成分有很大不同，但与来自俄罗斯的毛桦树皮中的油的成分非常相似。纸皮桦内皮油的主要成分是反式α-佛手柑油烯（18%）、芳姜黄烯（12%）、E-β-法呢烯（12%）、Z-β-法呢烯（10%）和顺式α-佛手柑油烯（8%）。
