Isolation and characterization of bioactive phenolic compounds from Cinnamomum camphora barks

Two new phenolic rhamnosides ( ) and 12 known phenolic compounds ( ) were isolated from the ethanolic extract of barks by repeated column chromatography. The structures of all isolated compounds were identified by comprehensive spectroscopic data analysis such as high-resolution electrospray ionizat...

Zusammenfassung:	Two new phenolic rhamnosides ( ) and 12 known phenolic compounds ( ) were isolated from the ethanolic extract of barks by repeated column chromatography. The structures of all isolated compounds were identified by comprehensive spectroscopic data analysis such as high-resolution electrospray ionization mass spectra, nuclear magnetic resonance, optical rotatory dispersion and chemical method. assay revealed that compound showed strong inhibitory activity against tyrosinase, and compounds , , , showed obvious acetylcholinesterase inhibitory activity.
