inactivated by heating. They found that the bactericidal
substance of onions differs from that of cabbage in that
it is only partially inactivated by heating. Both the
cabbage and, onion extracts were active against Escherichia
coli. They further concluded that cabbage may have a
beneficial effect in controlling the bacterial flora of
the alimentary canal.^3
Little and Grnb&ugh (1944) found that extracts of
various plants were inhibitory to the bacterial phyto-
patkogens but are much more active against animal pathogens.
Beans, com* cabbage* cauliflower, and tomatoes were all
active with the juices of corn begng the most generally
active. The Inhibition was more pronounced against the
gram-negative bacteria.
Irving (1947) described the antibiotic agent extracted
from the tosato plant as a water and alcohol soluble,
heat stable, organic compound of relatively lew molecular
weight. He stated further that this resin, tomatin, in-
hibits many organisms besides bacteria. These include
higher fungi and yeast-like forms. Tomatin or similar
substances o&eur in plants such a# the potato, sweet potato,
