Abstract
A methanol extract of Physalis alkekengi var.francheti showed a potent cell differentiation inducing activity toward mouse myeloid leukemia cell line (M1 cells). From the extract, a new physalin and two new neo physalins, 25,27-dihydro-4,7-didehydro-7-deoxyneophysalin A and 4,7-di dehydroneophysalin B, were isolated along with physalin A, L and isoph ysalin B. The structures of physalins and neophysalins were determined by means of NMR, UV, IR and mass spectra. Of these compounds, physali n A showed potent cell differentiation inducing activity.
