Four active principles, 1, 2, 3 and 4, were isolated from Polygara senega var. latifolia TORR. et GRAY by a combination of partition and column chromatography on silica gel and octadecyl silica gel (ODS), monitored by a hair-regrowth activity assay. Compounds 1, 2, 3 and 4 were identified as senegose A, senegin II, senegin III, and senegasaponin b by comparison of their spectral data with those of authentic samples.
