Inhibitory effect of hena (Lawsonia inermis leaves) and carrot root on aflatoxin production byAspergillus parasiticus

Experiments were undertaken to evaluate the effect of some natural products (hena, and carrot root) on growth and aflatoxins production byAspergillus parasiticus FRR 2752. Powdered hena (0.5 and 5%) inhibited mycelial growth and delayed 1 sporulation ofA parasiticus during 7 days. The inhibition of growth was increased with increasing the added amount. Aflatoxins production byA parasiticus was reduced with 40–100% in the presence of hena (Lawsonia inermis leaves). Carrot root extract stimulated the fungal growth and aflatoxin production, whereas carrot root fibers slightly enriched fungal growth, inhibited aflatoxins production (B₁, G₁, and G₂), but there was no inhibition of aflatoxin B₂ production byA parasiticus.
