Novel ferulic acid and benzophenone derivatives from the flower buds of Syzygium aromaticum

Abstract

Phytochemical investigation of clove resulted in the isolation of two new natural compounds, a ferulic acid derivative, sabrinic acid (1) and a benzophenone derivative (2) together with two known compounds kaempferol-3,5-dimethyl ether (3) and 4-methyl benzoic acid (4). Compounds 3 and 4 were isolated for the first time from the genus Syzygium. The structures of compounds were elucidated through modern spectroscopic techniques including 1D and 2D NMR spectroscopy.
