Abstract

A new α-pyrone, 6R-[5R,6S-diacetyloxy-1Z,3E-heptadienyl]-5,6-dihydro-2H-pyran-2one (1), along with six known compounds including an α-pyrone, flavones and terpenes was isolated from the aerial parts of Neohyptis paniculata. The structure of 1 was established unambiguously by MS and a series of 1D and 2D-NMR spectroscopic analyses. The antibacterial activity of the compounds (1-7) was investigated against five strains of multi-drug resistant (MDR) and methicillin-resistant Staphylococcus aureus and minimum inhibitory concentrations (MICs) of these compounds were found to be in the range of 64-256 μg/mL.
