Abstract:The extract from Leontopodtum leontopodioides 50~ 100mg/kg ip has been proved able to suppress theswelling of normal or adrenalectomised rat hind paws induced by RPA,and strongly inhibit the cutaneous hemor-rhage of animals induced by RPA , lysosome or lysosome of broken membrane. It has also been shown that the ex-tract 100 mg/kg ip can markedly inhibit the migration of leukocytes. These suggest that the anti-inflammatoryproperties of the extract are not dependent on the pituitary-adrenal system or membrane of lysosome.
