Phytochemical investigation of the 1-BuOH-soluble fraction of the MeOH extract of Alangium premnifolium resulted in the isolation of ten megastigmane glycosides, of which, two, (6R, 9R)-3-oxo-α-ionol apiofuranosylglucopyranoside and roseoside with (6S, 9R)-blumeol A as an aglycone were known. The structures of the eight new compounds were determined by spectroscopic methods.
