Ten new compounds isolated from the heartwood of Combretum psidioides have been shown to be 7-hydroxy-2,4,6-trimethoxy-, 7-hydroxy-2,3,4,6-tetramethoxy-, 2,7-dihydroxy-3,4,6-trimethoxy-, and 2,6,7-trihydroxy-3,4-dimethoxy-phenanthrene, the 9,10-dihydro-derivatives of these four compounds, and 4′-hydroxy-3,4,5-trimethoxy-and 4,4′-dihydroxy-3,5-dimethoxybibenzyl.
从Combretum psidioides的心材中分离出的十种新化合物已显示为7-羟基-2,4,6-三甲氧基-,7-羟基-2,3,4,6-四甲氧基-,2,7-二羟基-3 ,4,6-三甲氧基-和2,6,7-三羟基-3,4-二甲氧基菲,这四个化合物的9,10-二氢衍生物和4'-羟基-3,4,5-三甲氧基-和4,4'-二羟基-3,5-二甲氧基双苄基。
