Isolation, Synthesis and AChE Inhibitory Potential of Some Novel Cinnamyl Esters of Taraxerol, the Major Metabolite of the Mangrove Bruguiera cylindrica

Systematic chemical screening of the leaves of Bruguiera cylindrica, the tree mangrove of Rhizophoraceae family, afforded five single and pure compounds. The structures of the isolated compounds were established by their spectroscopic data as taraxerol ( 1 ), 3 β ‐( E )‐coumaroyltaraxerol ( 2 ), 3 β ‐( Z )‐coumaroyltaraxerol ( 3 ), β ‐sitosterol ( 4 ), and eicosanol ( 5 ). In view of significant accumulation and interesting biological...
