Abstract

Extracts of Clitoria ternatea (butterfly pea) flowers are used in Thailand as a component of cosmetics and the chemical composition of the flowers suggest that they may have antioxidant activity. In this study the potential antioxidant activity of C. ternatea extracts and an extract containing eye gel formulation was investigated. Aqueous extracts were shown to have stronger antioxidant activity (as measured by DPPH scavenging activity) than ethanolic extracts (IC50 values were 1mg/mL and 4 mg/mL respectively). Aqueous extracts incorporated in to an eye gel formulation were also shown to retaining this activity however it was significantly less than a commercial anti-wrinkle cream included for comparison. Total phenolic content was 1.9 mg/g extract as gallic acid equivalence. The data from this study supports the use of C. ternatea extracts as antioxidant inclusions in cosmetic products.
