title: [Elimination of poison from Halitum violaceum by processing].
abstract: The contents of polysulphides in different forms of Halitum violaceum (unprocessed, processed with vinegar, calcinated and boiled with water) were determined indirectly by UV spectrophotometry. The results showed that the unprocessed forms are higher in the contents of polysulphides while the processed ones have little or no such contents at all. It is thus believed that the poisons can be eliminated from Halitum violaceum by processing, which helps to decrease or eliminate polysulphides and sulphides.
