Analysis of Rhaponticum carthamoides (Willd.) Iljin crude extracts composition and ability to simulate cell proliferation

Planta Medica 2009; 75: 1019: Abstract PI3

Further analysis revealed that the ability of compounds present in Rhaponticum carthamoides leaves extracts to stimulate keratynocytes proliferation was lower than mentioned in the abstract PI3 (corrected results: 122% for alpha-amyrin, 115% for beta-sitosterol after 24 hr incubation, no activity in case of stigmasterol and cholesterol). The effect observed previously should be ascribed rather to cytoprotective potential, as the solvent used (absolute ethanol) contained some toxic additives, probably due to dehydration process. GS-MS analysis data are correct.
