In vitro determination of anti-lipid peroxidation assay was performed according to the method of Wills [26 (link)]. Briefly, the reaction mixtures contained 2.0 ml of the TCA-TBA-HCl reagent (15 % (w/v) Trichloroacetic Acid (TCA; Lot No# LM06461808; Loba Chemie), 0.375% (w/v) Thiobarbituric Acid (TBA; Lot No# SG53121901; Loba Chemie), and 0.25 N Hydrochloric Acid (HCl; CAS No# 7647-01-0; Fisher Chemical) and 1 ml of tests extracts of different concentrations (50, 100, 150 and 200 μg/ml) or standard (L-Ascorbic acid; CAS No# 21675-47-8; Sigma Aldrich, Germany). The resulting mixtures were incubated in a water bath (Labtech) set at 90 °C for 10 min, cooled, and Centrifuged at 10,000 rpm using a Labtech Centrifuge for 15 min. The supernatants were aspirated, and their respective absorbances measured at 532 nm using a double beam UV-Vis spectrophotometer (Shimadzu UV-Vis 1601).

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.
