In this study, methanol (MeOH), anhydrous sodium sulfate (Na₂SO₄), sodium chloride (NaCl), potassium hydroxide (KOH), methyl-tert-butyl ether (MTBE), and deionized water (>18 MΩ∙cm resistivity) were used. The aforementioned products were purchased from Sigma-Aldrich (Life Science Chemilab S.A., Athens, Greece). Supelco™ (Munich, Germany) 37 component fatty-acid methyl ester (FAME) mix was also used. The FAME mix contains the methyl esters of 37 fatty acids (catalog no. 47885-U) in a concentration of about 2% and 4% of each fatty-acid methyl ester. Palmitic acid methyl ester and tridecanoid acid in FAME mix were also purchased from Sigma-Aldrich in 6% and ≥99% concentrations, respectively.
Also, Folin–Ciocalteu, sodium carbonate in anhydrous crystal form, gallic acid, ethanol, 2,2-diphenyl-1-picrylhydrazyl (DPPH), methanol, and 2,2’-azino-bis(3-ethyl-benzthiazoline-sulfonic acid) (ABTS) were used as compounds and for antioxidant activity determinations.

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.
