Abstract

|
|
To investigate ginseng oligopeptides with biological activities, the water extract was purified by ultra-filtration, gel filtration, ion-exchange and thin layer chromatography. Ultra-filtered water extract exhibited antilipolytic activity, inhibiting epinephrine-induced lipolysis in the isolated fat cells of rat epididymal adipose tissue. The filtrate was separated into 3 fractions by Sephadex G-25 gel filtration. Peptides were found only in the first fraction(S-FI). Saponine and sugars were also detected in tie fraction. S-FI fraction resolved further into 6 fractions by Dowex 50 ion-exchange chromatography. The sugar and saponine depleted fraction(P-F2) from the second chromatography showed antilipolytic activity. The P-F2 fraction revealed 6 spots on TLC. The 6 spots were isolated by TLC and identified as peptides.
