✦ Synopsis

Eight new acylated preatroxigenin saponins 1 ± 8 were isolated as four inseparable mixtures of the transand cis-4-methoxycinnamoyl derivatives, atroximasaponins A 1 /A 2 (1/2), B 1 /B 2 (3/4), C 1 /C 2 (5/6) and D 1 /D 2 (7/8) from the roots of Atroxima congolana. These compounds are the first examples of triterpene saponins containing preatroxigenin ( (2b,3b,4a,22b)-2,3,22,27-tetrahydroxyolean-12-ene-23,28-dioic acid as aglycone.
