Key Word Index-Maytenus diversifolia; Celastraceae; cytotoxic and antileukemic activity; maytenfoliol; maytenfolic acid; maytensifolins -A and -B; canophyllol; pachysonol; 29-hydroxyfriedelan-3-one; 30-hydroxyfriedelan-3-one; maytansine.The known compounds maytansine and sitosterol-β-D-glucoside as well as the new triterpenes maytenfoliol and maytenfolic acid were isolated as antileukemic agents from Maytenus diversifolia.Other triterpenes isolated included the new maytensifolin-A and -B as well as the known friedelin, canophyllal, β-amyrin, canophyllol, pachysonol, 29-hydroxyfriedelan-3-one and 30-hydroxyfriedelan-3-one.

Two new trioxygenated D:A-freidooleananes from the stem bark of Elaeodendron glaucum have been shown to be the angular methyl dioxygenated 25,28-dihydroxy-D:A-friedooleanan-3-one (2) and 25-hydroxy-3-oxo-D:A-friedooleanan-28-al (3).

Two new trioxygenated D:A-friedo-oleananes from Elaeodendron glaucum have been shown to be the angular methyl dioxygenated 25,28-dihydroxy-D:A-friedo-oleanan-3-one(1) and 3,28-dioxo-D:A-friedo-oleanan-25-ol(2) by interconversion and deoxygenation of the alcohol(2) using Lithium-ethylene diamine reduction coupled with spectroscopic methods.
