Abstract: A new ursane-type triterpenoid, 3β-hydroxy-urs-30-p-Z-hydroxycinnamoyloxy-12-en-28-oic-acid (1), together with three known triterpenoids, 3β-hydroxy-urs-30-p-E-hydroxycinnamoyloxy-12-en-28-oic-acid (2), 2α,3β,19α-trihydroxy-urs-12-en-28-oic-acid (3), and ursolic acid (4), four known lignans, pinoresinol (5), 9α-hydroxypinoresinol (6), (+)-medioresinol (7), and (+)-kobusin (8), and two steroids, β-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 1–4 were evaluated for their inhibitory activities against 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1).
Keywords: Teucrium viscidum; triterpenoids; lignans; 11β-HSD1
