Five new compounds isolated from the heartwood of Combretum apiculatum have been shown by chemical and spectroscopic methods, supported by synthesis, to be 4,7-dihydroxy-2,6-dimethoxy-, 4,7-dihydroxy-2,3,6-trimethoxy-, and 2,6-dihydroxy-3,4,7-trimethoxy-9,10-dihydrophenanthrene, and 2,6-dihydroxy-3,4,7-trimethoxy- and 4,6,7-trihydroxy-2,3-dimethoxyphenanthrene.
通过化学和光谱方法,在合成的支持下,已从五味子草心材中分离出的五种新化合物为4,7-二羟基-2,6-二甲氧基-,4,7-二羟基-2,3,6-三甲氧基-和2,6-二羟基-3,4,7-三甲氧基-9,10-二氢菲,和2,6-二羟基-3,4,7-三甲氧基-和4,6,7-三羟基-2, 3-二甲氧基菲。
