%X A new ursane-type triterpenoid, 3 ¦Â-hydroxy-urs-30- p- Z-hydroxycinnamoyloxy-12-en-28-oic-acid ( 1), together with three known triterpenoids, 3 ¦Â-hydroxy-urs-30- p- E-hydroxycinnamoyloxy-12-en-28-oic-acid ( 2), 2 ¦Á,3 ¦Â,19 ¦Á-trihydroxy-urs-12-en-28-oic-acid ( 3), and ursolic acid ( 4), four known lignans, pinoresinol ( 5), 9 ¦Á-hydroxypinoresinol ( 6), (+)-medioresinol ( 7), and (+)-kobusin ( 8), and two steroids, ¦Â-sitosterol ( 9), and daucosterol ( 10), were isolated from the whole parts of Teucrium viscidum. Their structures were established by a combination of spectroscopic data analysis, besides comparison with literature data. Compounds 1¨C 4 were evaluated for their inhibitory activities against 11 ¦Â-hydroxysteroid dehydrogenase 1 (11 ¦Â-HSD1).
