摘要

Guinea-pigs were protected against the lethal effects of a histamine aerosol by intraperitoneal injection of stable extracts of normal tomato plants and of tomato plants infected with crown-gall tumours. The protection was short-lasting. No difference was observed between the activities of extracts of normal and of infected plants. The active principle of the extracts was isolated, and identified as the steroid alkaloid glycoside, tomatine.
