ISOLASI TERPENOID FRAKSI AKTIF ANTIOKSIDAN DARI DAUN ANDONG (Cordyline fruticosa [L.] A. Cheval)

Abstract: The  isolation  of  terpenoids  from  Andong  leaf  extracts  has  been  done  by  maceration  method using n-hexane, etil acetate and methanol solvents. The antioxidant properties of extracts from each solvent were measured by DPPH method. Antioxidant activity (IC50) of each extracts were: 134,09  mg/L;  86,378  mg/L  and  86,815  mg/L  for  n-hexane,  etil  acetate  and  methanol respectively.  Etil  actate  extract  had  the  highest  antioxidant  activity  compared  to  others.  The extract of etil acetate was separated by colomn chromatography by using silica gel as stationary phase  and  n-hexane,  etil  acetate  and  methanol  as  mobile  phase.  The  chromatography  process was  using  Step  Gradient  Polarity  (SGP)  method.  The  result  compunds  were  white  solid  form which  gave  single  stain  for  some  eluens  in  Thin  Layer  Chromatography  (TLC)  and  having melting point at 124,7 to 125,9o  C. The characterization of isolate compound was done by using UV spectrophotometer, resulting that the absorbant of isolate compound was at 200 nm, while Infra Red (IR) measurement resulting wave numbers 3415,82 cm-1, 1636,53 cm-1, 2917,18 cm-1and 1375,16 cm-1 each for OH, alkene, C-H stretching and CH3 functional groups.
