EXTRAIT PURIFIE ISOLE A PARTIR DE PSEUDOLYSIMACHION ROTUNDUM VAR SUBINTEGRUM ET COMPOSITION LE COMPRENANT POUR PREVENIR OU TRAITER UNE INFLAMMATION, UNE ALLERGIE ET L'ASTHME
The present invention relates to inventive novel industrialized method for preparing purified extract containing more abundant active ingredients such as catalpol derivatives from the extract of Pseudolysimachion rotundum var subintegrum than that prepared by the conventional preparation method disclosed in the prior art and the therapeutics or functional health food comprising the purified extract for treating and preventing inflammatory, allergic or asthmatic disease. The purified extract showed more potent anti-inflammatory, anti-allergy and anti-asthma activity than that prepared by the conventional preparation method disclosed in the prior art through various in vivo tests such as inhibition test on the reproduction of eosinolphil, the release of immunoglobulin and inflammatory chemokines in plasma and bronchoalveolar fluid as well as the suppression of airway hyperresponsiveness and golblet cell hyperplasia in a OVA-sensitized/challenged mouse model.
