Lampiran 1. Alur Pembuatan Ekstrak Buah Mengkudu

  12 Kg Buah mengkudu dipotong tipis- tipis

Dikeringkan dalam lemari pengering dengan

о suhu 40-50 C , selama ± 5 hari

Potongan-potongan yang sudah kering

dihancurkan menggunakan belender 1,2 Kg serbuk diekstrak dalam 4.000 ml etanol 70% 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

  о evaporator dengan suhu tidak lebih 40 C.

  

Hasil ekstraksi dikeringkan dengan alat
