Popis: Four triterpenoids ( 1 – 4 ), nine steroids and steroid glycosides ( 6 – 11 , 13 – 15 ) and two flavonoids ( 17 – 18 ) were isolated from the roots of Clerodendrum indicum , whereas three triterpenoids ( 1 , 4 and 5 ), six steroids and steroid glycosides ( 9 – 10 , 12 – 14 , 16 ) and one phenylethanoid glycoside ( 19 ) were obtained from the roots of Clerodendrum villosum . This is the first report of chemical constituents of C. villosum , and the first report of compounds 1 , 3 – 4 , 6 – 11 and 13 – 15 from C. indicum . Among the steroids isolated, six of them are the characteristic 24β-ethylsteroids with Δ 25 -unsaturation. Their chemotaxonomic significance within the subfamily Ajugoideae (Teucrioideae) of the family Lamiaceae is discussed.
