Inhibitory action of extracts of Maclura aurantiaca and Epilobium hirsutum on tumour models in mice.

Primary screening of alcohol extracts of fruits of Maclura aurantiaca (Moraceae) and the overground part of Epilobium hirsutum (Onagraceae) was conducted in order to test the anti-tumour action on models in mice. Applied in doses of 100 mg/kg and 90 mg/kg, Maclura extract increased the life span of the mice by 158 and 152% accordingly in leucosis P-388 and ascitic tumour of Ehrich. In doses of 1 mg/kg and 3 mg/kg the Epilobium extract prolonged the life span of the mice by 156 and 158% accordingly in leucosis P-388 and ascitic tumour of Ehrlich.
