Nine triterpenoids, squalene (1), cycloartanol (2), 24-methylenecycloartanol (3), dammara-20, 24-dien-3β-ol (4), 24-methylenedammar-20-en-3β-ol (5), α-amyrin (6), β-amyrin (7), 19α H-lupeol (8) and isoarborinol (9), have been isolated from the leaves of L. stenocephala. Three triterpenoids, butyrospermol (10), isobauerenol (11) and lupeol (12), have been isolated from the roots of L. stenocephala. Their structures were determined on the basis of spectral data.},
