Abstract:
Nagpur mandarin is one of the best mandarins in the world. In India Citrus is the third largest fruit industry after Banana and Mango. Citrus fruits are commonly used for juice production, where tons of pulp peel and rags are thrown solid waste during the extraction process. The fruit waste generation not only results in financial losses but also adds to the expense of waste management and disposal. Orange peel, which is the primary waste fraction in the production of orange juice, contains are fiber, vitamin C, folate, vitamin B6, calcium and other essential nutrients. The skin of the oranges contains a good amount of polyphenols that protect against several diseases. Due to their low cost and high availability in the world, C. reticulata peels and their phytochemical compounds could serve as a cheap and yet nutritional dietary supplement or even as a catalyst in the synthesis of green nanoparticles. This study aims to assess the photo chemical compounds of C. reticulate peel powder extract. TPC was found to be higher in ethanolic extract (190 mg/g) than in aqueous extract (132 mg/g) according to the phytochemical screening results. DPPH radical scavenging activity was highest in ethanol extract (73.64%) and aqueous extract (52.18%). In comparison to aqueous extract, ethanol extract exhibited the greatest concentration of phenolic compounds in the HPLC profile. However, there is a need exploit further studies on plant origin of C. reticulata peel powder is still needed.
