Galic Acid Standard

INTRODUCTION

Gallic acid is a polyphenol produced by plants, which shows antioxidant properties. It is commonly used to measure polyphenol concentration but could also be used to measure antioxidant capacity. It is present in a wide variety of plant-based food samples.

RECOMMENDED USES

To compare the e-BQC results (µC) to classical antioxidant capacity units of Gallic acid Antioxidant Capacity Equivalents (GAE). It could be used for biological and food samples.

COMPATIBLE BUFFERS

ReferenceProductDescription
ST08006Bio-Buffer150 mM Sterile PBS pH 7.4
ST08007General Buffer100 Mm PBS pH 7
ST08005Nutrition Buffer0.1 M PBS pH 5.8

 

STANDARD CALIBRATION

Add 1 ml of the selected diluent buffer to the vial (10 mM). Transfer the 1 ml from the vial and add 9 ml of diluent (1 mM). Prepare the calibration curves in 1.5 ml tubes as shown below:

 Standard (µl)Diluent (µl)GAE (µM)
1010000
21099010
32597525
45095050

*This is just a recommendation in case the expected antioxidant capacity values of the sample were unknow. You are free to adapt the concentrations to be tested to your necessities.

e-BQC SPECIFICITY

Gallic acid is more predominantly present in Q2 where it has higher sensitivity. It is recommended to use Q2 for calibrations at low concentrations of Gallic acid.
