Two New Saponins fromPhytolacca americana
Planta Medica, 1987Two 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- D-xylopyranosyl]phytolaccagenic acid, respectively.

Purification and biological activities of pokeweed (Phytolacca Americana) mitogens
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1976Five mitogens, designated Pa-1 through Pa-5, were purified from the roots of pokeweed (Phytolacca americana) by means of ethanol fractionation, DEAE-cellulose column chromatography, affinity chromatography on a column of desialized human erythrocyte glycopeptide-Sepharose 4B, and gel filtration.

Accumulation and interaction of calcium and manganese in Phytolacca americana
Plant Science, 2009To further understand the hyperaccumulation of Mn, the present study investigated the accumulation of Ca and Mn and their interaction in Mn hyperaccumulator pokeweed (Phytolacca americana Linn.). Exogenous Ca was observed to have a distinctive impact on the Mn phytotoxicity and accumulation in pokeweed, but exogenous Mn had little influence on the ...

Accumulation and uptake of manganese in a hyperaccumulator Phytolacca americana
Minerals Engineering, 2007Abstract Phytolacca americana (pokeweed) has been found to be a new manganese hyperaccumulator plant by means of field surveys on Mn-rich soils and by Hydroponics experiments. This species not only has remarkable tolerance to Mn but also has extraordinary uptake and accumulation capacity for this element.

Isolation and characterization of a protease from Phytolacca americana
Phytochemistry, 1988Abstract A cysteine protease of M r 26 000 has been isolated in homogeneous form from the fruit juice of Phytolacca americana . The enzyme, named phytolacin, has a maximum activity in the pH range 7.5–9.0 and contains carbohydrate moiety. The substrate specificity of phytolacin differs from that of papain.

Bioactive Triterpene Saponins from the Roots of Phytolacca americana
Journal of Natural Products, 2008Five new triterpene saponins named phytolaccasaponins N-1 (1), N-2 (2), N-3 (3) N-4 (4), and N-5 (5) were isolated from the roots of Phytolacca americana together with seven known triterpene saponins (6-12). The structures of the five new saponins were established as shown in structures 1-5 on the basis of their spectroscopic data.
