The naturally dropped immature fruits of Citrus reticulata Blanco are generally discarded as waste but they have enormous potential to be used as nutraceuticals. This work was planned to evaluate the proximate, mineral composition, total phenolic and flavonoid content, antioxidant and antimicrobial potential of dropped fruits of C. reticulata Blanco. Proximate analysis showed them as a good source of carbohydrates and proteins. Mineral analysis revealed the presence of K, Mg, P, Ca and Na as macronutrients and Fe, B, Mn and Ni as micronutrients. The total phenolic and flavonoid content of methanol extract and its fractions ranged between 2.47 and 51.36 mg gallic acid equivalent g⁻¹ DW and 11.47–86.50 mg quercetin equivalent g⁻¹ DW respectively. The antioxidant potential of dropped Citrus fruits was determined by two in vitro (DPPH and ABTS) assays and various enzymatic antioxidant assays. Maximum …
