【摘要】 用紫外分光光度法间接测定紫硇砂生品、醋制品、煅品和单煮品中多硫化物的含量,结果生品中含有较多的多硫化物,其他炮制品含量较少或没有。认为炮制可以除毒主要是炮制后多硫化物和硫化物减少或除净的结果。更多还原

【Abstract】 The contents of polysulphides in different forms of Halitum violaceum (unprocessed, processed with vineger, 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.更多还原
