THE ALLELOPATHIC POTENTIAL OF GINSENOSIDES 167
Figure 3. HPLC Analysis of Ginsenosides. Ginsenosides were isolated from spent
broth in which either no organism (upper trace), Trichoderma hamatum (middle trace)
or Pythium irregulare (lower trace) had been cultured for five days at 25 o C in the
dark. Ginsenosides were chromatographed on a Microsorb-MV C-18 column (150 x
4.6 mm, 5 mm) using an acetonitrile:H 2 O gradient (Nicol et al., 2002), and detected
at 203 nm. The * in the lower trace indicates the unknown metabolite found in the
spent broth of Py. irregulare.
