摘要
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 neophysalins, 25,27-dihydro-4,7-didehydro-7-deoxyneophysalin A and 4,7-didehydroneophysalin B, were isolated along with physalin A, L and isophysalin B. The structures of physalins and neophysalins were determined by means of NMR, UV, IR and mass spectra. Of these compounds, physalin A showed potent cell differentiation inducing activity.
