Triterpenoid saponins from Panax zingiberesis and their network analysis of their chemotaxonomic significance

In a phytochemical investigation of Panax zingiberesis , a medicinal species in China, the following triterpenoid saponins were isolated and identified: notopanaxoside A ( 1 ), majonoside R 2 ( 2 ), majonoside R 1 ( 3 ), ginsenoside Rb 1 ( 4 ), pseudoginsenoside RT 4 ( 5 ), vina-ginsenoside R 1 ( 6 ), ginsenoside R O ( 7 ), chikusetsusaponin IV ( 8 ), and vina-ginsenoside R 2 ( 9 ). Compounds 1 , 3 , 5 , 6 , and 9 were found in P. zingiberesis for the first time. Network analysis was used to examine the chemotaxonomic significance of the compounds. • Nine triterpenoid saponins were isolated from Panax zingiberesis . • Five compounds were isolated from P. zingiberesis for the first time. • The compound-species network study demonstrated the chemotaxonomic value of the isolated compounds.
