The chemical composition of the essential oil of Cacalia hastata L. var. orientalis has been investigated by GC and GC-MS. Important odor-active compounds were detected in the oil by GC-MS/Olfactometry (GC-MS/O) and aroma extraction dilution analysis (AEDA). Fifty-one compounds were identified in the oil by GC-MS. The major components of the essential oil were (+)-(4S)-cacalohastine (48.8%), germacrene D (11.4%), and myrcene (10.2%). GC-MS/O and AEDA showed that γ-terpinene, hexanol, and p-mentha-2,4(8)-diene were the most characteristic aroma compounds of the oil. It seems that these components are responsible for the fresh odor of C. hastata L. var. orientalis.
通过气相色谱（GC）和气相色谱-质谱联用（GC-MS）对东风兔儿伞（Cacalia hastata L. var. orientalis）精油的化学成分进行了研究。采用气相色谱-质谱联用/嗅觉测定法（GC-MS/O）和香气萃取稀释分析（AEDA）在该精油中检测到了重要的气味活性化合物。通过GC-MS在该精油中鉴定出了51种化合物。该精油的主要成分是（+）-（4S）-东风兔儿伞碱（48.8%）、杜松烯D（11.4%）和月桂烯（10.2%）。GC-MS/O和AEDA表明，γ-松油烯、己醇和对-薄荷-2,4(8)-二烯是该精油最具特征性的香气化合物。看来这些成分赋予了东风兔儿伞清新的气味。
