The fractionation of Eugenia caryophyllata (Myrtaceae) guided by the syncytia formation inhibition assay led to the isolation of four tannins (eugeniin, casuarictin, 1,3-di-O-galloyl-4,6-(S)-hexahydroxydiphenoyl-beta-D-glucopyranose, and tellimagrandin I), and two chromones (biflorin and
We found that the 50% aqueous EtOH extract of clove (Syzygium aromaticum) had potent dose-dependent inhibitory activity toward glycogen phosphorylase b and glucagon-stimulated glucose production in primary rat hepatocytes. Among the components, eugeniin inhibited glycogen phosphorylase b and
The antiviral substance from the bud of Syzygium aromatica was purified by ether and ethyl acetate extraction and successive chromatography on Sephadex LH-60, LH-20, G-25 and Lichroprep RP-18. The purified antiviral substance was homogeneous and identified as eugeniin. Eugeniin shows antiviral
