the methodologies of Peng et al. (2005) were also similar to those used by Wang et al. (2010), Bertoldi et al. (2019), and Islam et al. (2017) due to the involvement of high performance liquid chromatography and diode array detector. The uniqueness of this experiment was on the particular focus on compound zeaxanthin dipalmitate in the standard procedures of the laboratory while the project completed here did not rely on the same chemical compound. During extraction, variety of reagents like ethyl acetate, chloroform, and petroleum ether were used. Samples of ground goji berries were mixed with 5ml of water and then subjected to sonication to enhance extraction. The residue was then collected and dried using a combination of methods including the microwave. After that, 50ml of petroleum ether was mixed with acetone in the ratio of 1:1 and blended with goji extracts before sonicating the mixture for 30 minutes. The resulting residue was mixed with 10ml of ethyl acetate and divided into portions for high performance liquid chromatography and UV spectrophotometry. Therefore, it is evident that despite the similarities in standard procedures of determining chlorophyll and carotenoid as used in this project, the experiment by Peng et al. (2005) used unique techniques in deriving the results.
