Two new triterpenoid saponins,cincholic acid-3- O - β - D -xylopyranoside,28- O - β - D -glucopyranosyl ester (1),quinovic acid-28- O - β - D -glucopyranosyl ester (4),and a new phenolic glucoside,4-[4’- O -( 2’,3’,5’,6’-tetrahydroxy phenyl)- β - D -glucoside]-1-butene (2),along with five known triterpenoid saponins and one phenolic glucoside were isolated from the n -butanol fraction of the stems of Luculia pinciana Hook. Their structures were established by means of spectroscopic methods.
Two new triterpenoid saponins, cincholic acid - 3 - O - β - D - xylopyranoside, 28 - O - β - D - glucopyranosyl ester (1) a new phenolic glucoside, 4- [4’-O- (2 ’, 3’, 5’-6’-tetrahydroxy phenyl) -β-D-glucoside] and one phenolic glucoside were isolated from the n -butanol fraction of the stems of Luculia pinciana Hook. Their structures were established by means of spectroscopic methods.
