Prenylated flavon and antibacterial activities of Artocarpus lanceifolius Roxb bark

Abstract

Abstract Prenylated flavone compounds, 14-hydroxyartonin E have been isolated from CHCl3 extract of Artocarpus lanceifolius Roxb bark. The molecular structure compound was determined based on the UV-Vis, IR, 1H-NMR and 13C-NMR HSQC, HMBC spectra and compared to the previous data reported.14-hydroxyartonin E compound provides antibacterial activity with a moderate category against Streptococcus pneumonia and Staphylococcus aureus but the category is weak against Escherichiacoli and Salmonella thyposa
