Three new physalin steroids, physalin III (1), physalin IV (2), 3-O-methylphysalin X (3), together with five known physalins (4-8) were isolated from the 80% EtOH extract of calyces of Physalis alkekengi var. franchetii. The structures of the new compounds were revealed through 1D and 2D NMR and mass spectroscopic studies.
