A complete inhibition in aflatoxin production by Aspergillus flavus was observed with greater than 4.5 mg ml ‐1 of 20 g 100 ml ‐1 leaf extract of Amorphophallus campanulatus (OL). Suppression in growth was also well pronounced (81% at 8.0 mg ml ‐1 ). The comparative efficacy of the corm of the plant was lower. Calcium oxalate, an important constituent of ‘OL’, completely checked the growth and toxin biosynthesis at 0.4 mg ml ‐1 concentration.
