Description Three monodesmosidic glucuronide saponins of barringtogenol C, named barringtosides A, B and C have
been isolated as their methyl esters from the dried seeds of Barringtonia acutangula. On the basis of chemical and
spectral evidence, the structures of these new saponins were elucidated to be as follows: barringtoside A, 3-O-fl-Dxylopyranosyl(
1 ~3)-[fl-D-galactopyranosyl(1 ~2)]-fl-D-glucuronopyranosyl barringtogenol C; barringtoside B, 3-0-
ff-D-xylopyranosyl(1 ~ 3)-[fl-D-galactopyranosyl(1 ~2)]-fl-D-glucuronopyranosyl-21-O-tigloyl-28-O-isobutyryl barringtogenol
C; barringtoside C, 3-O-ct-L-arabinopyranosyl(lo3)-[fl-D-galactopyranosyl(l~2)]-fl-D-glucuronopyranosyl
barringtogenol C.
