Abstract
Bunga Telang (Clitoria ternatea L.) mengandung antosianin yang berperan sebagai antioksidan alami. Penelitian ini bertujuan mengembangkan ekstrak kental menjadi ekstrak kering serta mengevaluasi kadar antosianin dan aktivitas antioksidannya. Ekstraksi dilakukan dengan metode maserasi menggunakan etanol 70%. Ekstrak kental yang diperoleh kemudian dibuat menjadi ekstrak kering dengan penambahan filler avicel pH 101 (1:2) dan aerosil (1:1) dan (1:2). Penetapan kadar antosianin dilakukan dengan metode pH diferensial sedangkan aktivitas antioksidan diuji menggunakan metode DPPH (2,2-difenil-1-pikrihidrazil) dengan spektrofotometer UV-Vis. Ekstrak kental memiliki kadar antosianin sebesar 9,128 mg/100 g, ekstrak kering avicel (1:2) sebesar 7,347 mg/100 g, ekstrak kering aerosil (1:1) sebesar 8,017 mg/100 g, dan ekstrak kering aerosil (1:2) sebesar 7,069 mg/100 g. Pada konsentrasi 100 µg/mL inhibisi terhadap DPPH dari ekstrak kental sebesar 50,969%, ekstrak kering avicel konsentrasi 300 µg/mL sebesar 42,556%, ekstrak kering aerosil (1:1) konsentrasi 200 µg/mL sebesar 36,291% dan ekstrak kering aerosil (1:2) konsentrasi 300 µg/mL sebesar 31,821%. Proses pembuatan ekstrak kering serta penggunaan filler menghasilkan kadar antosianin dan aktivitas antioksidan yang lebih rendah dibandingkan ekstrak kental. ------ Butterfly pea flower (Clitoria ternatea L.) contains anthocyanins that act as natural antioxidants. This study aimed to convert a viscous extract into a dry extract and evaluate its anthocyanin content and antioxidant activity. Extraction was carried out by maceration using 70% ethanol. The resulting viscous extract was converted into dry extracts by adding Avicel pH 101 (1:2) and aerosil (1:1 and 1:2) as fillers. Anthocyanin content was determined using the pH differential method, while antioxidant activity was evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay with a UV-Vis spectrophotometer. The anthocyanin content of the viscous extract was 9.128 mg/100 g, while the dry extracts prepared with avicel pH 101 (1:2), aerosil (1:1), and aerosil (1:2) contained 7.347, 8.017, and 7.069 mg/100 g, respectively. The DPPH radical scavenging activity of the viscous extract was 50.969% at 100 µg/mL, whereas the dry extracts showed 42.556% inhibition at 300 µg/mL for avicel pH 101, 36.291% at 200 µg/mL for aerosil (1:1), and 31.821% at 300 µg/mL for aerosil (1:2). Dry extract preparation and the use of fillers resulted in lower anthocyanin content and antioxidant activity than the viscous extract.
