Abstract
Bunga telang (Clitoria ternatea L.) memiliki kandungan senyawa bioaktif flavonoid, fenol, tanin, saponin, triterpenoid, alkaloid, dan antosianin yang memiliki manfaat sebagai antioksidan, antibakteri, dan antiinflamasi. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi suhu ekstraksi terhadap kadar fenolik total, flavonoid total dan analisis aktivitas antioksidan. Metode ekstraksi menggunakan ultrasonik dengan variasi suhu 40 °C, 50 °C, dan 60 °C. Aktivitas antioksidan menggunakan metode DPPH (2,2-difenil-2-pikrihidrazil). Sementara metode pengukuran kadar fenolik total menggunakan metode FolinCiocalteu dan metode kolorimetri AlCl3 untuk mengukur kadar flavonoid total. Hasil penelitian menunjukkan bahwa nilai kadar fenolik total tertinggi di ekstraksi suhu 60 °C sebesar 8,451 ± 0,075 mg GAE/100g dan kadar flavonoid total tertingi di ekstraksi suhu 60 °C sebesar 3,215 ± 0,052 mg QE/100g, sementara ekstraksi pada suhu 40 °C memiliki aktivitas antioksidan lebih baik dengan nilai 217,502 (kekuatan sedang) dibanding suhu ekstraksi (50 °C dan 60 °C). Kesimpulan pada penelitian ini suhu ekstraksi mempengaruhi kadar fenolik total dan flavonoid total tetapi tidak mempengaruhi aktivitas antioksidan. ------ Butterfly pea flower (Clitoria ternatea L.) contains bioactive compounds such as flavonoids, phenols, tannins, saponins, triterpenoids, alkaloids, and anthocyanins, which possess antioxidant, antibacterial, and anti-inflammatory properties. The aim of this study was to determine the effect of extraction temperature variations on total phenolic content, total flavonoid content, and antioxidant activity. Ultrasonic extraction was carried out at temperatures of 40 °C, 50 °C, and 60 °C, and antioxidant activity was measured using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Total phenolic content was determined using the Folin–Ciocalteu method, while total flavonoid content was measured using the aluminum chloride (AlCl₃) colorimetric method. The results showed that the highest total phenolic content (8.451 ± 0.075 mg GAE/100 g) and total flavonoid content (3.215 ± 0.052 mg QE/100 g) were obtained at 60 °C. In contrast, extraction at 40 °C exhibited better antioxidant activity, with a value of 217.502 (moderate strength), compared to extractions at 50 °C and 60 °C. In conclusion, extraction temperature influences total phenolic and flavonoid contents but does not affect antioxidant activity.
