In leaves, roots and calli of P. dodecandra we found two 28,30-dicarboxyolean-12-enes and their glycosides in addition to the hitherto known four 28-monocarboxyolean-12-enes on which the chemotaxonomy was based. Therefore, P. dodecandra can no longer be considered as chemotaxonomically different
The methanolic extract of the berries of Phytolacca tetramera, an Argentinean species submitted to a great anthropic impact, and therefore in critic risk of extinction, not previously studied, showed antifungal activity against opportunistic pathogenic fungi. Through fractionation of the extract
The methanol extract form the leaves of Phytolacca icosandra L., afforded the unprecedented artificial triterpenoid fatty acid ester 1 derived from the new natural triterpenoid phytolaccagenic acid 3-O-myristate (1a), along with the three known triterpenoids serjanic, acinosolic and phytolaccagenic
Two new monodesmosidic saponins (Phytolaccosides F and D (2)) have been isolated from the roots of PHYTOLACCA AMERICANA and identified as 3- O-[alpha- L-rhamnopyranosyl(1-->2)-beta- D-glucopyranosyl (1-->2)-beta- D-xylopyranosyl]phytolaccagenic acid and 3- O-[beta- D-glucopyranosyl(1-->2)-beta-
Phytolacca acinosa is an herb for treatment of ascites and tumor. Two forms of phytolacca acinosa, i.e. raw and vinegar-processed herb, have been used in clinic. However, pharmacokinetic difference between the two forms of phytolacca acinosa has not been fully understood. Herein, a comparative
In Phytolaccaceae family, Phytolacca americana L. (American pokeweed) and P. esculenta Van Houtte (Chinese pokeweed) are the two representative species among the genus. Pokeweeds have triterpenoid saponins as toxic compounds in every part of the plant. The saponins phytolaccoside A, B, D, E, and G
