Notes:
Various extractives of onion were tested for their inhibitory activity towards the growth of the aflatoxin-producing fungi, Aspergillus flavas and A. parasiticus. Ether extract and lachrymatory factor (LF), which has been earlier identified as thiopropanal-s-oxide, were found to have potent antifungal activity. Steam-distilled onion oil, which is devoid of LF, was not as potent as ether extract and LF. Its major component, dipropyldisulfide was ineffective as a fungal inhibitor. Ethyl acetate extract containing phenolics was also ineffective. Exposure of onions to gamma-irradiation at a sprout-inhibiting dose (6 krad) did not alter the inhibitory potency of the onion extractives which, however, appeared to be heat-labile.
