PROCEDE POUR PREPARER NOUVELLE SAPONINE TRITERPENIQUE DERIVEE DE LA CAULOPHYLLOGENINE ET SES APPLICATION THERAPEUTIQUES

摘要

The present invention concerns a new triterpenic saponin derived from caulophyllogenin, the process for extracting it from varieties of Chrysanthellum, and its therapeutic use. This saponin is characterized as being the ester of O- beta -D-glucosyl-3 beta -caulophyllogenin and an oligosaccharide comprising two units of L-rhamnose and two units of D-xylose. It is extracted from vegetable matter and purified using pressurized liquid preparative chromatographic techniques. This saponin is useful in human and veterinary therapeutics in phlebology, rheumatology, and traumatology.
