Synthesis of Cycloartan‐16β‐ol from 16β 24R‐Epoxy‐Cycloartane and Their Cytotoxicity Evaluation Against Human Cancer Cell Lines

Chemistry &Biodiversity, Volume 21, Issue 5, May 2024.
Abstract It was found that Argentatins A and B triterpenoids make up approximately 20–30 % of the waste resin produced from the industrial processes to isolate rubber from P. argentatum. We have developed an efficient protocol for synthesizing cycloartane‐16β‐ol derivatives by opening the oxepane ring of argentatin B acetate (2) with BF3‐OEt2. Although

Stress-Induced Proteins in Parthenium argentatum Leaves

Biologia plantarum, 2003
We have analyzed the stress-associated proteins in a high-rubber-yielding guayule (Parthenium argentatum Gray cv. 11591) leaves. Protein profiles in leaf fractions, resolved by SDS-PAGE and visualized by Coomassie Brilliant Blue staining, were different under various stresses.

Seed quality of guayule (Parthenium argentatum Gray)

, 2006
The germination potential of guayule seed is considered too poor for direct seeding. Relating seed quality to field conditions could provide information on suitable locations and management to improve seed quality. The study objective was to determine seed quality of guayule grown under different field conditions in Arizona.
