A New Phenolic Glycoside from the Barks of Cinnamomum cassia

摘要

A new phenolic glycoside (>1), named methyl 2-phenylpropanoate-2-O-β-d-apiofuranosyl-(1→6)-O-β-d–glucopyranoside, was isolated from the barks of Cinnamomum cassia, along with three known phenolic glycosides and four known lignan glycosides. The structure of >1 was elucidated by extensive interpretation of spectroscopic data and chemical method. Selected compounds were evaluated for their immunosuppressive activities against murine lymphocytes. Compounds >1, >2, >6 and >8 exhibited differential inhibition against ConA-induced T cells proliferation.
