Abstract: Objective To research the derivatives of panax notoginseng sapogenins and their anti-tumor activities. Me thods The ginsenosides Rg1 was treated with Smith degradation. The products were separated and purified by silica gel column chromatography. The structures of the products were determined by NMR spectra. The activity of anti-tumor cells of compound (1) and 1'-hydroxyethanedioxy PT was detected with CDC25 B activity assay and fluorescence technique. Re s ults 1'-hydroxyethanedioxy PT, 20 (s) -protopanaxatriol (PT) , and24, 25-en-3β, 6 α-dihydroxy-12, 20- (1', 2'-isopropylidenedioxy) propanedioxy-dammarane (1) were isolated and identified. Conclus ion Compound (1) , named 1', 2'-isopropylidenedioxy-propanedioxy-propanedioxy, is a novel derivative of panax notoginseng sapogenin with better inhibitory activity against CDC25 B. -
