    Efficiency evaluation of phospholipid fatty acid method based on lipid standards: methanol failed to recover a majority of phospholipids yet eluted unexpected glycolipid by Shanshan Zhang, Shanshan Zhang, Xinyu Jiao, Hongzhang Kang, Wenjuan Yu, Wenjuan Yu

    Published 2025-05-01
    “…Overall, incomplete separation among lipid types caused loss of phospholipids and introduction of glycolipid interferences in the methanol fraction, leading to biased estimation of soil microbial biomass and composition. Chloroform elution of phospholipids challenges the principle of “like dissolves like” in solid-phase chromatography, although we cannot rule out the uncertainty caused by background PLFAs and future experiments are needed to provide more evidence. …”
