Cinnamomum utile Kosterm. is a Philippine endemic tree that reaches a height of nearly 10–15 m and with a diameter at breast height of around 30–60 cm. The species was previously known to be found only in Mindanao Island, Philippines at mid to high elevations , but samples used in this study were collected from the slopes of Mt. Baloy, Iloilo, Philippines, thus extending its distribution range to Panay Island, Central Philippines. The bark and leaves of C. utile have a very strong cinnamon odor. The locals collect and prepare the leaves and bark as a decoction for cough.
This study was conducted as part of our research on the chemical constituents of Cinnamomum species found in the Philippines. We earlier reported the isolation of a new monoterpene natural product and a new sesquiterpene, along with the known compounds 4-hydroxy-3-methoxycinnamaldehyde, 4-allyl-2-methoxyphenol, α-terpineol, and humulene from the dichloromethane (DCM) extract of the bark of C. cebuense,while the...
