Acetic acid (glacial) and anhydrous sodium carbonate were purchased from Riedel-de Haën (Hanover, Germany). Gallic acid monohydrate was obtained from Fluka (Sigma-Aldrich, Milan, Italy), methanol from VWR Prolabo (Fontenay-sous-Bois, France), and Folin-Ciocalteu's (FC) reagent from Labochimica (Padova, Italy). Chlorogenic acid hemihydrates, maltose, D-(+)-glucose, and D-(-)-fructose were purchased from Aldrich Chemical Company (Sigma-Aldrich); caffeic acid, p-coumaric acid, and ferulic acid from Sigma and methanol from Carlo Erba (Milan, Italy). Deionized water (18 MΩ) was prepared using an ultrapure water purification system (Arium ® pro; Sartorius, Muggiò, Italy). All reagents and standards were of analytical and high-performance liquid chromatography (HPLC) grade.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
