The essential oil obtained from the leaves of Cupressaceae were analyzed in this study. The volatile oil was obtained by ethyl acetate distillation and then analyzed by gas chromatography-mass spectrum(GC-MS). The study showed that Sabina procumbens (Endl.) Iwata et Kusaka, Sabina virginiana (L.) Antoine, Sabina squamata (Buch.-Hamilt.) Ant and Sabina chinensis(L.) Antoine cv. Pfitzeriana (Sabina), Fokienia hodginsii (Dunn) Henry et Thomas (Fokienia hodginsii) and Chamaecyparis obtuse cv. Tetragon (Chamaecyparis) were mainly composed of terpene and alcohols. American arborvitae, Thuja standishii (Gord.) Carr, Thuja occidentalis L. (valuable arborvitae), Cupressus arizonica Greene (cypresses) and Platycladus orientalis ‘sieboldii' (Platycladus) were mainly composed of terpene, alcohols and ketones. There were 49 kinds of common components (≥6) in 11 kinds of plants, accounting for only 10.71% of all essential oil components, and more specific components (≤5), common composition and unique elements together make each plant smell differently.
