Popis:	Two new triterpenes cycloartane-type, named 24-methylencycloartan-12-oxo-3β,22α-diol and trichiliol, were isolated from the leaves of Trichilia casaretti C. DC. together with three known triterpenes—24-methylencycloart-3β,22-diol, 22,25-dihydrocycloart-23(E)-en-3β-ol, and 22(R)-hydroxycycloart-24-en-3-ol. These compounds were characterized on the basis of their spectral data, mainly 1D (1H and 13C) and 2D NMR (1H-1H-COSY, 1H-1H-NOESY, HMQC, HSQC, and HMBC), and mass spectra (EI-MS and HR-ESI-MS), also involving comparison with data from the literature.
