Cell suspension cultures from hypocotyl-derived callus of Hyssopus officinalis were found to produce two sterols i. e. beta-sitosterol (1) and stigmasterol (2), as well as several known pentacyclic triterpenes with an oleanene and ursene skeleton. The triterpenes were identified as oleanolic acid (3), ursolic acid (4), 2alpha,3beta-dihydroxyolean-12-en-28-oic acid (5), 2alpha,3beta-dihydroxyurs-12-en-28-oic acid (6), 2alpha,3beta,24-trihydroxyolean-12-en-28-oic acid (7), and 2alpha,3beta,24-trihydroxyurs-12-en-28-oic acid (8). Compounds 5-8 were isolated as their acetates (6, 8) or bromolactone acetates (5, 7).
