Agricultural Waste–Derived Biochar for Antibiotics Removal in Aqueous Environment: A Comprehensive Outlook

open access: yesJournal of Chemistry, Volume 2025, Issue 1, 2025.
Increased antibiotic consumption and inadequate management procedures expose the environment to antibiotics, leading to significant antibiotic pollution and emerging antibiotic‐resistant microbes. Biochar form agricultural waste can efficiently remove antibiotics from aquatic environments and is a renewable and cost‐effective adsorbent.

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

open access: yesChemistry &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

SC-CO2 Extraction of guayule biomass (Parthenium argentatum) – yield and selectivity towards valuable co-products, lipids and terpenics [PDF]

open access: yes, 2016
Guayule (Parthenium argentatum) a shrub native to Mexico, is now being acclimated in Europe as a potential crop. The main extractible fractions are polyisoprene (similar to Hevea rubber) for producing tires and allergy-free gloves and resin (GRe).
