Abstract
Three monodesmosidic glucuronide saponins of barringtogenol C, named b arringtosides A, B and C have been isolated as their methyl esters fro m the dried seeds of Barringtonia acutangula. On the basis of chemical and spectral evidence, the structures of these new saponins were eluc idated to be as follows: barringtoside A, galactopyranosyl(1-->2)]-bet a-D-glucuronopyranosyl barringtogenol C; barringtoside B, -D-glucurono pyranosyl-21-0-tigloyl-28-0-isobutyryl barringtogenol C; barringtoside C, galactopyranosyl(1-->2)]-beta-D-glucuronopyranosyl barringtogenol C.
