Methods for determining thioglucosides in<i>Crambe abyssinica</i>

Abstract

Abstract Four methods are described for the determination of thioglucosides in Crambe abyssinica : sulfate ion, sulfur balance, silver complexing, and hot‐water extraction. The analytical results of all four methods agree closely as to the thioglucoside content in dehulled, defatted meal, from 11舑12%. Any one of these methods should be useful in studying new plant species because approximate thioglucoside content is obtained even though the specific thioglucosides and isothiocyanates involved may not be known.
