Five monodesmosidic serjanic acid saponins and a monodesmosidic spergulagenic acid saponin were isolated from an aqueous extract of the berries of Phytolacca icosandra. A methanol extract of the berries furnished three bidesmosidic serjanic acid glycosides. Their structures were established by spectroscopic (ES-MS, 1H NMR, COSY, HSQC, HMBC, 13C NMR) and chemical methods. The molluscicidal, spermicidal and haemolytic properties of the saponins were investigated. (C) 2000 Elsevier Science Ltd.

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.
