Abstract

L'invention concerne un complexe bioactif d'acides triterpéniques, tel quel ou sous la forme de sels de Na, K, NH4 présentant une pureté de 90 % au minimum, avec une teneur standardisée constituée : d'un minimum de 75 % d'acide ursolique, de 10 à 15 % d'acide oléanolique et de 4 à 10 % d'autres acides triterpéniques constitués d'un ou de plusieurs des acides suivants : hydroxyursolique, hydroxyoléanolique, bétulinique, déhydrobétulinique, produit à partir des végétaux Salvia sp., Lavandula sp., Sambucus nigra et Crataegus sp. Le procédé de production prévoit l'augmentation de la sélectivité et des rendements des étapes d'extraction, de purification et de crystallisation par utilisation d'eaux structurées (eau à pH acide 'I' et eau à pH alcalin 'S') dans la composition de solvants utilisés. Le complexe bioactif d'acides triterpéniques présente une activité pharmacologique marquée et diversifiée permettant de bioréguler le métabolisme protéinique, glucidique et lipidique, en particulier sur des organismes âgés, ainsi qu'une activité immunoprotectrice, anti-oxydante, hépatoprotectrice et retardatrice de la progression tumorale, ledit complexe étant conditionné sous la forme de nouveaux produits médicinaux à usage interne et/ou externe pouvant être utilisés dans la thérapie humaine et vétérinaire.
