  • Composition comprising an extract of and tiarellic acid isolated therefrom having antiinflammatory, antiallergic and antiasthmatic activity
    Patent number: 7763286
    Abstract: The present invention relates to a composition comprising an extract of Tiarella polyphylla, and tiarellic acid isolated therefrom having anti-inflammatory, anti-allergic and anti-asthmatic activity. The extract of Tiarella polyphylla and the tiarellic acid isolated therefrom shows the inhibitory effect on the LTC4 release in vitro test and the suppressive effect on the IgE level and the cytokine (IL-4, IL-5 and IL-13) production, airway hyperresponsiveness, and leukocyte infiltration in OVA-induced asthmatic mice. Therefore, it can be used as the therapeutics or functional health food for treating and preventing inflammatory, allergic and asthmatic disease.
