Spectrophotometric methods for the determination of total polyphenols and flavonoids are often used because they simple, sensitive, precise. Before using these methods, must be validated to ensure quality obtained data prove that method is suitable its purpose. The aim this study was validate spectrophotometric flavonoids. has been according polyphenol standards, which belong groups phenolic ac...

Carbohydrates are digested in vivo gastrointestinal hydrolysis system the body. To investigate glycemic evaluation of carbohydrate digestion, a lot study literature, vitro to research postprandial glucose composition with biochemical systems for carbohydrates hasn’t been met. In this study, it was investigated by using after digestion bread species from different countries such as United States...

We are proposing the first widely applicable spectrophotometric method, after minimal pretreatment, for irinotecan quantification in plasma, to guide personalized dose adjustment and quality control of bulk or injection dosage.

Several researchers have proposed spectrophotometric modifications of the Winkler titrimetric method for measuring dissolved oxygen (DO). These modifications, although simple, are not widely used because of concern about accuracy, calibration, and possible sources of interference. Here we show, using natural samples from lakes and rivers as well as samples manipulated in the laboratory, that th...
