Novel Paper Strip Extraction Method for Xanthohumol, a Prenylflavonoid Derived from Hops

摘要

1. Paper strip extraction was comparable in terms of accuracy (≤ 15% average error), precision (≤15% RSD), and recovery to liquid-liquid extraction. 2. Paper Strip Extraction resulted in 77-97% accuracy over a large range of concentrations, 6-12% RSD for precision, and losses of 25% or less for XN and its metabolites. 3. Paper strip extraction offers several benefits over liquid-liquid extraction including less solvent use, lower labor costs, and less investigator exposure to toxic solvents.
