Localisation of thiamine within the cotyledon of dormant groundnut (Arachis hypogaea L.)

Utilising non‐aqueous differential centrifugation for isolation of subcellular components from groundnuts, it appears that intracellular thiamine is predominantly non‐particulated. A large proportion of the total thiamine of the cotyledon is associated with cell wall material, most likely due to inward migration of the vitamin from the testa during curing.
