      Abstract
      Katarak diabetik adalah gangguan penglihatan yang paling umum terjadi pada penderita diabetes melitus. Proses terjadinya katarak pada penderita diabetes melitus merupakan akibat peningkatan enzim aldosa reduktase. Bunga telang telah terbukti secara in vitro memiliki senyawa aktif yang berpotensi sebagai antikatarak, namun potensi dari setiap senyawa aktif sebagai inhibitor aldosa reduktase belum diketahui. Penelitian ini bertujuan mengetahui senyawa aktif bunga telang yang berpotensi menghambat aldosa reduktase secara in silico dengan metode penambatan molekuler. Hasil penelitian menunjukkan 5 dari 27 senyawa aktif bunga telang berpotensi sebagai inhibitor aldosa reduktase berdasarkan hasil penapisan virtual, uji bioavailabilitas, uji toksisitas serta interaksi ligan-reseptor. Ligan tersebut adalah apigenin, epikatekin, ?-tokoferol, a-tokoferol dan ternatin. Senyawa aktif apigenin adalah metabolit sekunder berjenis flavonoid yang berpotensi paling baik dalam inhibisi aldosa reduktase dengan nilai ?G sebesar -10.341 kcal/mol dan Kd sebesar 2.629 × 10^4 pM, serta berinteraksi dengan 16 residu asam amino.
       
      Diabetic cataracts are the most common visual impairment in people with diabetes mellitus. The process of cataracts in diabetes mellitus sufferers is the result of an increase in the aldose reductase enzyme. Butterfly pea flowers have been proven in vitro to contain active compounds that have the potential to act as anti-cataracts, but the potential of each active compound as an aldose reductase inhibitor is unknown. This study aimed to determine the active compounds of butterfly pea flowers that have the potential to inhibit aldose reductase in silico using the molecular docking method. The results showed that 5 of the 27 active compounds of butterfly pea flower had potential as aldose reductase inhibitors based on the results of virtual screening, bioavailability tests, toxicity tests and ligand-receptor interactions. The ligands are apigenin, epikatekin, ?-tokoferol, a-tokoferol and ternatin. The active compound apigenin is a flavonoid secondary metabolite that has the best potential in inhibiting aldose reductase with a ?G value of -10.341 kcal/mol and Kd of 2.629 × 10^4 pM, and interacts with 16 amino acid residues
