A new iridoid glycoside, named physaloside A (1), together with one known iridoid glycoside (swertiamarin, 2), was isolated from the EtOAc extract of Physochlaina physaloides (L.) G. Don. The structure elucidation of 1 was carried out by 1D NMR (1H and 13C NMR) and 2D NMR (COSY, HSQC, HMBC, and NOESY) spectral analysis. Antibacterial activities of the compounds were evaluated against various bacteria.
