Abstract
Three new triterpenoids, 3β-hydroxy-urs-30-p-Z-hydroxycinnamoyl-12-en-28-oic-acid (1), 3β-hydroxy-olean-30-p-Ehydroxycinnamoyl-12-en-28-oic-acid (2) and 3β,6α-dihydroxy-urs-14-en-12-one (3), together with seven known triterpenoids, were isolated from the roots of Rubia schumanniana. Their structures were established by means of spectroscopic analysis. All compounds were evaluated for cytotoxic activity, and compounds 2–6 showed cytotoxicity with the IC50 values of 10.75∼18.87 µg/mL.
