Saponins derived from Ilex pubescens and method of purifying the same

總結: It introduces a novel triterpene saponin fraction (named PSF) with anti-inflammatory and analgesic activities. Two hitherto unreported novel triterpene saponins were isolated in substantially pure form from the root of Ilex pubescens. The chemical structures and some properties of the triterpene saponin fraction have been elucidated to possess anti-inflammatory and analgesic activity. These two novel triterpene saponins and the triterpene saponin fraction may be used as pharmaceutical compositions in humans and mammals in need of such treatment.

技術優勢: Suitable for oral administration with better efficacy, Pure herbal extracts with minimal side effect
