Comparison of Phytochemical Content in Clitoria Ternate Flowers and Roselle Flowers as Functional Drink Ingredients in Kediri, Indonesia

Abstract

Clitoria ternatea, or butterfly pea flower, is a tropical plant with high historical and cultural value, especially in traditional medicine in Indonesia and Asia. This plant is rich in bioactive compounds such as phenols, terpenoids, and alkaloids, which support its various pharmacological activities, including as an antioxidant, antidiabetic. Roselle petals contain bioactive compounds with high anthocyanin content. The research problem is that the flowers used as functional beverage ingredients do not yet have information on their phytochemical compounds. The study aims to examine the comparison of phytochemical compound content in butterfly pea flowers and roselle flowers as coloring ingredients for functional beverages. Anthocyanins, which are a group of flavonoids, act as natural antioxidants. The research method uses quantitative tests on both types of flowers. The parameters measured are DPPH, polyphenols, anthocyanins, fiber, and vitamin C. The research results explain that butterfly pea flowers contain an IC50 value of 25.1559-29.9034 μg/mL, protein around 10-15%, fiber 20-30%, Vitamin C 100-200 mg/100g, minerals including potassium, calcium, and magnesium, phenol 13.8%, and anthocyanin 0.1-0.5%. The roselle flower has an IC50 of around 33.79 μg/mL, total phenolics of 2086.32 μg/mL, Vitamin C around 244-260 mg/100g, and anthocyanin around 0.1-0.5%. Its minerals include calcium, magnesium, and potassium
