Cinnamomum trichophyllum Quis. & Merr. (Lauraceae) grows in mid-elevation mountains in the Philippines and Indonesia . To date, there are no reported chemical studies and biological activities of C. trichophyllum. There are 21 species of Cinnamomum founded in the Philippines, of which 16 are known to be endemic. This study was conducted as part of our research on the chemical constituents of Cinnamomum species founded in the Philippines.
We reported herein the isolation and identification of the chemical constituents of the dichloromethane extracts of the bark and leaves of C. trichophyllum from Jamildan, Capiz, Philippines. The leaves of C. trichophyllum yielded eugenol (1) , β-sitosterol (2) , and polyprenol (3) , while the bark afforded trilinolein (4)  and a mixture of β-sitosterol (2) and stigmasterol (5) . To the best of our knowledge, this is the first report on the isolation of these compounds from C. trichophyllum.
Eugenol (1) is a constituent common to five...
