New strategies to analyze argentatins A and B in guayule (Parthenium argentatum, A. Gray)

open access: closedTalanta, 2023
There is considerable interest in the exploitation of compounds belonging to the triterpenoid family from guayule (Parthenium argentatum, A. Gray), as they offer several beneficial effects to human health. The most abundant triterpenoids in guayule resin are the argentatins, which are currently analyzed by labor-intensive and time-consuming techniques.

Evaluation of the cytotoxicity, cytostaticity and genotoxicity of Argentatins A and B from Parthenium argentatum (Gray)

open access: closedLife Sciences, 2005
Argentatins A and B are abundant triterpenes present in Parthenium argentatum. Both compounds have shown cytotoxic properties on K562, MCF-7, PC-3, HCT-15 and U251 human cancer cell lines. Furthermore the cytotoxic, cytostatic and genotoxic effects of the argentatins on proliferating lymphocytes were evaluated using cytokinesis-block micronucleus test.
