Abstract

Abstract From the crude drug ‘Brazil ginseng’, the roots of Pfaffia iresinoides, a large amount of ecdysterone has been isolated together with polypodine B and pterosterone. The ecdysterone content of each part of the plant was determined by high pressure liquid chromatography quantitative analysis. A triterpenoid saponin, chikusetsusaponin IVa has also been isolated.
