experiment conducted by Islam et al. (2017), the procedures revealed slight differences when compared to the methodology used in this research and the techniques applied by Donno et al. (2015). Nonetheless, both procedures acknowledged the significance of spectromatography in conducting UV analysis and absorbance of goji berry extracts. In this research by Islam et al. (2017), the methods used applied the technique of testing antioxidant capacities of the sample as illustrated by Donno et al. (2015). The procedure involved extracting samples of goji berry and applying tests using various chemical and reagents such as; Folin-Ciocalteu, sodium carbonate, TPTZ, potassium persulphate, and ferric chloride (Islam et al. 2017). A comparison of these two experiments revealed that some chemical and reagents were used in both instances. In addition, the extraction process was a standard procedure of grinding the dry berries, adding solvents, and centrifuging the mixture. Islam et al. (2017) then applied multiple tests for evaluating different attributes of the extract. The coordination of these tests was different from the procedures used in this project as well as the earlier experiment
