Chinese arborvitae, oriental thuja, **Morgenländischer Lebensbaum**

Evergreen tree, endemic to northwestern China.

"A small tree 6 m or more tall with compact conical or columnar habit. Branches and branchlets ascending, closely appressed. Foliage dark green. Leaves borne in flattened frond‑like branchlets; scale‑like, opposite decussate. Male cones terminal on the branchlets; microsporophylis 6‑10 opposite decussate. Female cones green, woody and brown when ripe subglobose; Scales 8‑12, each with a curved process. Seeds ovoid, not winged... The `Chinese arbor‑vitae' is extensively planted as a road‑side tree or in gardens..." \\

"The composition of the hydrodistilled essential oils from the fruits and leaves of Thuja orientalis L. grown in Iran was analyzed by GC/MS. Nineteen and twenty-eight compounds have been identified in the volatile oils of the fruit and leaf, respectively. While the fruit oil contained α-pinene (52.4%), Δ-3-carene (14.2%), α-cedrol (6.5%) and β-phellandrene (5.1%), the leaf oil contained α-pinene (21.9%), α-cedrol (20.3%), Δ-3-carene (10.5%) and limonene (7.2%) as the main components." \\
Minor components of the leaf oil were thymoquinone (0.2%), bornyl acetate (1.0%), and geranyl acetate (0.4%) e.g. \\

"The essential oil from fresh leaves of Thuja orientalis L. grown in the north-western Himalaya was isolated by means of hydrodistillation and analyzed by GC and GC/MS. Twenty-two compounds representing 94.0% of the total oil were identified. The leaf oil contained α-pinene (29.2%), Δ-3-carene (20.1%), α-cedrol (9.8%), caryophyllene (7.5%), α-humulene (5.6%), limonene (5.4%), α-terpinolene (3.8%) and α-terpinyl acetate (3.5%) as major constituents. The essential oil showed antifungal activity against Alternaria alternata in a direct
bioautography assay." \\
