impatiens psittacina/過敏症

The allergy-preventive activity of a 35% EtOH extract (IT) of flowers of Impatiens textori MIQ. 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

Monitoring the blood flow of unanesthesized mice was found to be a reliable and effective method for studying their anaphylactic responses, in addition to the known method of monitoring blood pressure. Hen egg-white lysozyme (HEL)-specific anaphylaxis in mice was estimated by monitoring the decrease

BACKGROUND Impatiens textori Miq. (I. textori, Balsaminaceae) is a traditional medicinal herb used for centuries to treat several inflammatory related skin infections and allergic disorders in Asian countries. OBJECTIVE In this study, we elucidated the effects of whole plant extracts of I. textori

A 35% EtOH extract of flowers of Impatiens textori MIQ. showed an inhibitory effect on blood pressure decrease in response to platelet activating factor (PAF) measured with a blood pressure monitoring system. Bioassay-guided fractionation of the 35% EtOH extract (IT) led to isolation of the flavones
