 Endangered coniferous tree, up to 35m high, endemic to China.
-A study of the wood oil from C.macrolepis growing in Vietnam showed α-terpineol (11.6%), myrtenal (10.6%), bornyl acetate (5.6%) and carvacrol methyl ester % (5.6%) to be the main components. Furthermore, benzyl benzoate (7.8%), δ-cadinene (6.5%), verbenone (3.8%), piperitone (4,4%), and acetoveratrone (3,4-dimethoxyacetophenone, 2.1%) were present. \\

-"The wood is used for construction, but also for incense and EO distillation. Hydrodistillation using a Clevenger-type apparatus resulted in 0.3%, v/w, oil yield... This oil is dominated by monoterpene alcohols (25.8%) and monoterpene ketones (26.7%), with a further 7.1% of monoterpene ethers and 2.3% of monoterpene esters. The main component was the monoterpene ketone verbenone (9.3%), followed by piperitone (8.6%), α-terpineol (6.0%) and cis-beta-terpineol (5.3%). There is only one sesquiterpene hydrocarbon, cadalene (0.4%). The terpineol family, with 13.5%, is responsible for the odor, together with carvacrol and thymol methylether." \\
