Phytolacca thyrsiflora;Phytolaccaceae; triterpenoid saponins; glycosylphytolaccagenins; glycosylserjanoates; glycosylspergulagenates; glycosyl kaempferols; lignan; americanin A.The organs of Phytolacca thyrsiflora contain heterosides of different aglycones.In the roots only saponins based on phytolaccagenin and very probably on its de-O-methylderivative jaligonic acid have been located.The berries contain four new saponins based on serjanic acid.The de-O-methylanalogues, i.e. the spergulagenic acid derivatives, have so far been obtained only by saponification of the serjanoates.Finally, the leaves contain, besides glycosides of 7-O-methylkaempferol and of kaempferol, two of the new saponins based on serjanioc acid.Only the known lignan, americanin A, was isolated from the seeds.
