A new minor polyoxygenated triterpene named glutinolic acid (1) and two new aeginetic acid quinovosides (2, 3) were isolated from the roots of Rehmannia glutinosa LIBOSCH. (Scrophulariaceae) cultivated in Gunwi-gun, Korea. The structures of these compounds were established as 3 α,19 α,20 β,24,30-pentahydroxyurs-12-en-28-oic acid (1, glutinolic acid), aeginetic acid 5-O- β-D-quinovoside (2) and aeginetoyl ajugol 5″-O- β-D-quinovoside (3) on the basis of chemical and spectroscopic evidence.
