Determination of antioxidant activity of gum Arabic: an exudation from two different locations
Gum Arabic (GA) is the main product of acacia trees. As a raw and commercial samples, GA was extracted with methanol and analysed to measure the antioxidant activity using five methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH), Folin-Ciocalteu indexes (FCI), which indicate total phenolic compounds (TPC...

Gum Arabic (GA) is the main product of acacia trees. As a raw and commercial samples, GA was extracted with methanol and analysed to measure the antioxidant activity using five methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH), Folin-Ciocalteu indexes (FCI), which indicate total phenolic compounds (TPC), oxygen radical absorbance capacity (ORAC), ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC). This study used antioxidant assays to detect TPC and selected appropriate and inexpensive methods to determine the antioxidant capacity of GA samples. The results reveal that the FCI, ORAC, and CUPRAC are correlated highly with FRAP. Person’s correlation coefficient (r) values are 0.98, 0.93, and 0.99, respectively, based on the sample size of(n=8). This means that the TPC of GA is highly correlated with their antioxidant activities that are measured by these
three methods. Hence the FCI, ORAC, and the CUPRAC methods are more effective and simpler. They had similar
predictive power to the FRAP of GA antioxidant activity. Consequently, GA is generally recognized as being slightly
acidic which may have been obtained from appropriate methods of the antioxidant capacity detection. This acidity is
due to the electronic transfer mechanism based on the selection of the working pH. |
