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