Lampiran 1. Alur Pembuatan Ekstrak Buah Mengkudu

12 Kg Buah mengkudu dipotong tipis- tipis

Dikeringkan dalam lemari pengering dengan

suhu 40-50

о

C , selama ± 5 hari

1,2 Kg serbuk diekstrak dalam 4.000 ml etanol

70%

Potongan-potongan yang sudah kering

dihancurkan menggunakan

belender

Larutan disimpan dalam toples tertutup dan

dibiarkan sekurang-kurangnya selama 3 jam

 

Massa dipindahkan sedikit demi sedikit

kedalam perkolator sampai cairan mulai

menetes lalu perkolator dibiarkan selama 24

jam

Hasil penyarian diuapkan menggunakan

rotary

evaporator

dengan suhu tidak lebih 40
