Abstract

The research was carried out for the purpose of finding effects of gerbal saponins on aflatoxin synthesis by Aspergillus parasitics NRRL 2999. A. parasiticus with $10^6$ conidia were grown at $30^{\circ}C$ for 9 days on the enriched medium that is optimum for the frowth and aflatoxins production by the mold. The inhibitory effect on the growth and aflatoxins produced by the mold occurred in the presence of 0.36% of crude red-ginseng saponin showing both the growth and aflatoxins production come to 62.3% (growth), 38.7% (aflatoxin $B_1$) and 22.9% (aflatoxin $G_1$) of the control. Thd next effective saponin to inhibit the growth and aflatoxins production was from burdock seeds. However, saponin extracted from honeysuckle flowers had no inhibitory effect. The mold caused no changes in the pH of the medium when it contained red-ginseng saponin. Red-ginseng saponin was more effective than the white-ginseng in inhibiting both the growth and aflatoxin production.
