Triterpenoid saponins from Mimosa pigra.
Two novel triterpene glycosides have been isolated from Mimosa pigra. The aglycone of these two compounds was identified as machaerinic acid by 1H- and 13C-nmr spectroscopy and by comparison with an authentic sample. This aglycone is substituted at position C-3 by an identical oligosaccharide chain in these glycosides, and at position C-21 by either a Z/E-methoxycinnamic [1] unit or an E-cinnamic acid [2] unit.
