New Esters, 2‐(4‐Hydroxy‐3‐Methoxyphenyl)Ethyl Hexa‐ and Octacosanoates from the Leaves of Cinnamomum Reticulatum Hay

The leaves of Cinnamomum reticulatum Hay were extracted successively with hexane and acetone successively. Dipentadecyl ketone, n ‐dotriaconyl alcohol, 2‐(4‐hydroxy‐3‐methoxyphenyl)ethyl hexa‐ and octacosanoates ( two new esters from hexane extract ), β‐sitosterol, fatty acid, vanillin, p ‐hydroxybenzaldehyde, genkwanin, vanillic acid, p ‐hydroxybenzoic acid, β‐sitosteryl‐l‐β‐glucopyranoside, meso‐ erythritol, glucose, and 4‐(2‐hydroxyethyl)‐2‐methoxyphenyl‐l‐β‐D‐glucopyranoside (from the acetone extract) were isolated. The structures of the new esters were elucidated by chemical and physical evidence.
