摘要：

The new phenolic triterpenes, blepharodol (5) and 7 alpha-hydroxy-blepharodol (6) were isolated from Maytenus blepharodes and canarol (8), 7 alpha-hydroxy-canarol (9), 7-hydroxy-6-oxoiguesterol (11), canaradial (12) and the triterpene methylene quinones iguesteroquinone (13) and 7 alpha-hydroxy-7,8-dihydro-iguesterin (14) and were isolated from Maytenus canariensis. Their structures were elucidated by means of H-1 and C-13 NMR spectroscopic studies, including homo and heteronuclear correlations, DEFT, COSY, HMQC and HMBC experiments. These products are intermediates in the biogenetic pathway of methylene quinone triterpenes.
