【Abstract】 Seven phytoecdysteroids were isolated from the root of Rhaponticum uniflorum. Their structures, by means of spectroscopic techniques and chemical properties, were identified as ajugasterone C-2,3;20,22-diacetonide(1); 25-deoxy-9(11)-dehydro-20-hydroxyecdysone-20,22-amonocetonide(2); ajugasterone C-20,22-monoacetonide (3); ajugasterone C (4); rhapontisterone C (5); ecdysterone(6); 11α-hydroxyecdysterone ecdysterone(7). Compounds 1 and 2 were new compounds. Compound 3 was obtained from Rhaponticum uniflorum for the first time.更多还原
