摘要:The allergy-preventive activity of a 35% EtOH extract (IT) of flowers of Impatiens textori M IQ . was demonstrated in a continuing search for allergy-preventive substances from natural sources. The evaluation of its activity used an in vivo assay method for monitoring the blood flow decrease in the tail vein microcirculation of mice subjected to sensitization with hen-egg white lysozyme. Among the principal compounds in IT, apigenin (1), luteolin (3), and luteolin 7-glucoside (4) showed significant allergy-preventive effects.
