采用毛细管气相色谱和气相色谱-质谱联用技术对大黄樟和大黄樟地上部位的挥发油进行了研究。同时，采用GC-MS/O和香气提取稀释分析（AEDA）检测了精油中重要的芳香活性化合物。结果表明，鉴定出的化合物分别为79种和80种，分别占95.41%和98.37%。其主要成分为叶绿醇（667.4 μ g/100 g新鲜样品）、新叶绿烯（335.2 μ g）和γ -喜马偕烯（49.8 μ g）。另一方面，大黄油主要成分为叶绿醇（402.3 μ g）、亚油酸（289.4 μ g）和棕榈酸（241.4 μ g）。GC-MS/O和AEDA结果表明，(2E)-己烯醛和(2E, 4E)-非己烯醛是油中主要的香气化合物。似乎是这些成分制造了绿花香。另一方面，(2E)-己烯醇、(3Z)-己烯醇和1-辛烯-3-醇似乎形成了黄樟油的绿油味。
The essential oils from aerial parts of Elatostema laetevirens and Elatostema umbellatum var. majus were investigated by capillary GC and GC-MS. The important aroma-active compounds were also detected in the oil using GC-MS/O and aroma extraction dilution analysis (AEDA). As a result, 79 compounds of E. laetevirens and 80 compounds of E. umbellatum var. majus, accounting for 95.41% and 98.37%, were identified, respectively. The major components of E. laetevirens oil were phytol (667.4 microg/100 g fresh samples), neophytadiene (335.2 microg) and gamma-himachalene (49.8 microg). On the other hand, E. umbellatum var. majus oil contained phytol (402.3 microg), linoleic acid (289.4 microg) and palmitic acid (241.4 microg) as the major components. GC-MS/O and AEDA showed that (2E)-hexenal and (2E, 4E)-nonadienal were most aroma compounds of E. laetevirens oil. It seems that these components make the green-floral odor. On the other hands, it seems that (2E)-hexenal, (3Z)-hexenol and 1-octen-3-ol make the green-oily odor of E. umbellatum var. majus oil.
