Journal Highlight: Solid-phase extraction of plant thionins employing aluminum silicate based extraction columns

Date: Sep 15, 2014

Author: separationsNOW

A highly selective SPE method for plant thionins deployed aluminum silicate (3:2 mullite) powder as a sorbent and was illustrated by the extraction of viscotoxins, purothionins and hordothionins from European mistletoe, wheat and barley, respectively.
