Two new triterpenoid sapon.ins 1 and 2 were isolated from the crude saponin extract of Oxytropis glabra DC by Si gel chromato-grapny . Saponins 1 and 2 were determined to be 3-0-1 β-D-glucopyranosy 1 (1-2)- β -D-glucuronopyranosyl azukisapogenol methyl ester and 3-O-[β-D-glucopyranosyl(1 - 2 ) - β -D-glucuronopyranosyl] azukisapogenol amide, respectively by spectral analysis and chemical methods.
