| Abstract: | Оцінено реакційну здатність 18-молібдоди-
фосфатного гетерополікомплексу (18-МФК) щодо поліфеноль-
них сполук, які містяться в зелених чаях. В таких реакціях в
залежності від співвідношення відновника до 18-MФК спів-
існують одно- та двоелектронні гетерополісині. Результати
визначення загального вмісту поліфенолів у зелених чаях різних
марок, отриманих з 18-МФК та реагентом Фоліна-Чокальтеу,
близькі один до одного. Показані недоліки існуючих методів. The reactivity of 18-molybdodiphosphate heteropoly complex (18-MPC) with respect to the polyphenolic compounds contained in green teas was estimated. The one- and two-electron heteropoly blues coexist depending on the ratio of reducing agent to 18-MPC in such reactions. The results for the determination of total content of polyphenols in green teas of different brands obtained with 18-MPC and Folin- Ciocalteu reagent are close to each other. The disadvantages of the existing methods are shown. |
