Abstract


Telah dilakukan penelitian mengenai analisis kadar fenolik dan flavonoid total ekstrak daun anggur (Vitis vinifera L) dengan metode Spektrofotometri UV-Vis. Penelitian ini bertujuan untuk menentukan kadar fenolik dan flavonoid total dalam ekstrak etanol daun anggur. Sampel diekstraksi dengan metode maserasi menggunakan pelarut etanol. Penentuan kadar fenolik total ekstrak menggunakan pembanding asam galat dengan beberapa variasi konsentrasi. Penentuan kadar flavonoid total menggunakan pembanding kuersetin. Nilai absorbansi diukur dengan spektrofotometer. Nilai absorbansi kemudian dimasukkan ke dalam persamaan regresi linier. Hasil penelitian menunjukkan kadar total fenolik dan kadar total flavonoid dalam ekstrak berturut-turut adalah sebesar 95,28 mg GAE/g dan 4,07 mg QE/g.
