Using the α-and β-amylase isolated and purified from sweet potatoes and conmercial diastase, the authoress experimented on the influence of Vitamin C, hydrogen sulfide, potasium cyanide, glutathione on the activities of amylase.The results were as follows.1. The starch liquefying action of α-amylase was weakened by Vitamin C (reduced or oxidised form), glutathione, but not by H_2S. It was strengthened a little by KCN.2. By the addition of H_2S in the mixtures of starch, α-amylase and Vitamin C, the result was not altered, but the decrease of the starch-liquefying activity was recovered a little by KCN.3. The starch-saccharifying action of β-amylase was weakened by Vitamin C, but it was strengthened by H_2S, KCN and glutathione.4. By the addition of H_2S, KCN, glutathione, the decrease of the starch-saccharifying activities was perfectly recovered.
