Clitoria ternatea, also known as butterfly pea or blue pea, has many pharmacological and nutritional values. Stock solutions of flower extracts were prepared in different solvents, i.e., methanol (M), water (W), ethanol (E), glycerol (G), and glycerol/water (GW) to get extracts coded as (ME), (WE), (EE), (GE), and (GWE), respectively. A number of evaluations, such as microbial evaluation, phytochemical properties, mineral contents, and antioxidant activities, have been conducted on the blue flowers. The titration acidity reported 0.018 g citric acid/100 mL (CA) with a pH of 8.1. The total monomeric anthocyanin of blue pea flower was reported to be 77.31 mg/L cyanidin-3-glucoside according to the spectrophotometric assay. The hydrogen peroxide scavenging activity value of the ethanolic blue pea extract reported IC₅₀ = 25.37%. The results of the FRAP scavenging activity were expressed as IC₅₀ (%) and mg TE/L to reach IC₅₀ = 5.44% and 15.28 mg TE/L. The ethanolic extract was the most effective in the DPPH scavenging activity (EE) (IC₅₀ = 14.11 m g/mL), followed b y ME ( IC₅₀ = 12.25 m g/mL), and WE (IC₅₀ = 6.77 mg/mL). EE and WE reported the lowest values for total flavonoid contents (3.75 mg QE^g-1 and 2.49 mg QEg^-1, respectively). The antibacterial analysis reported the highest value, 25.14 mm, for Escherichia coli, followed by 20.87 mm for Bacillus cereus. The results for the cytotoxic impacts on Michigan Cancer Foundation-7 (MCF-7) breast cell lines demonstrated that the highest concentrations (500 μg/mL and 1000 μg/mL) showed significant cytotoxicity activities, lowering viability to <15%. Pea flowers can be considered as a food additive in acidic or even neutral foods. The high nutrient (anthocyanin and flavonoids) levels in blue pea flowers tend to increase their functional properties, such as antioxidant, antibacterial, and anticancer activities.
