New cinnamic acid esters from <b> <i>Ocimum basilicum</i> </b>

Abstract

Studies on the chemical constituents of the aerial parts of Ocimum basilicum have led to the isolation of a new ferulate, 4'-carbomethoxy-2'-hydroxy phenyl ferulate (1) and a new cinnamate, (E)-3'-hydroxy-4'-(1''-hydroxyethyl)-phenyl-4-methoxycinnamate (2). Their structures have been elucidated through spectral studies including 2D-NMR experiments (HMQC, HMBC, COSY-45 degrees , NOESY and 2D-J resolved).
