      Abstract
      ABSTRACTIn search development herbal medicine of selected plant for antidiabetic, ethyl acetate extract of Acorus cala-mus L. plays on biological role in differentiation of preadiposites and posses powerful in diabetes (type 2) and have known active compounds are 3-β, 22 α-trihiroksiolean-30-metoksikarbonil–12 ene-22-O-α-L-rhamnoside and β-sitosterol-3-O-β-D-glukosidase. The proposed of this search to isolate active compound which as inhibitor α-glucosidase activity from ethyl acetate extract and modify of active compounds or (SAR = Structure Activity Re-lationship). The results of fraction of ethyl acetate extracts were four semi-polar fractions which similar TLC spot (4, 5, 6 and 7 fractions) were active inhibition of α-glucosidase activity which IC50 22.86; 13.54; 13.34 and 18.92 ug/ml respectively and three polar fractions (20, 21 and 22 fractions) were active inhibition of α-glucosidase activity which IC50 13.55; 3.08 and 6.85 ug/ml respectively. SAR studied showed β-sitosterol-3-O-β-D-glukosidase with suspicion active compound have similarity with acarbose antidiabetic drug. This research should be contin-ued to establish of active compounds for further on antidiabetic drug design.ABSTRAKPenelitian sebelumnya menunjukkan bahwa ekstrak etil asetat rimpang Acorus calamus L. memiliki aktivitas biologis dalam diferensiasi pra-adiposit dan potensial dalam pengobatan diabetes tipe 2. Komponen aktif dalam ekstrak tersebut adalah 3-β, 22α-trihidroksiolean-30-metoksikarbonil-12 ene-22-O-α-L-rhamnosida dan β-sitosterol-3-O-β-D-glukosidase. Penelitian ini bertujuan untuk mengisolasi komponen ekstrak etil asetat rimpang Acorus calamus L yang memiliki aktivitas penghambatan enzim α-glukosidase serta melakukan modi-fikasi struktur komponen aktif (SAR: Structure Activity Relationship). Hasil penelitian menunjukkan terdapat 4 fraksi semi polar dengan profil KLT yang mirip (fraksi 4, 5, 6, dan 7). Keempat fraksi tersebut menghambat aktivitas enzim α-glukosidase dengan IC50 berturut-turut sebesar 13.54; 13.34; dan 18.92 µg/ml. Selain itu, terdapat pula 3 fraksi polar (fraksi 20, 21, dan 22) yang aktif dengan IC50 berturut-turut sebesar 13.55; 3.08; dan 6.85 µg/ml. Studi SAR menunjukkan bahwa β-sitosterol-3-O-β-D-glukosidase diduga memiliki struktur yang mirip dengan acarbose, suatu obat antidiabetes. Penelitian ini sebaiknya dilanjutkan untuk memperoleh komponen aktif yang dapat didesain sebagai obat antidiabetes.
