The structures of (3S,7R,13S)-6-[2-(dimethylamino)-3-phenylpropanoyl]-19-methoxy-2-oxa-6,9,15-triazatetracyclo[16.3.1.0(3,7). 0(9,13)]docosa-1-(22),16,18,20-tetraene-8,14-dione (1), nummularin-C (2) and nummularin-R (3) have been previously determined mainly based on mass spectrometric data. Stereochemistry and complete 1H and 13C NMR spectroscopic data assignments of these compounds are now described. Compounds 1 and 2 are reported for the first time from Zizyphus oxyphylla.
(3S,7R,13S)-6-[2-(二甲基氨基)-3-苯基丙酰基]-19-甲氧基-2-氧杂-6,9,15-三氮杂四环[16.3.1.0(3,7).0(9,13)]二十二碳-1-(22),16,18,20-四烯-8,14-二酮（1）、钱币菌素-C（2）和钱币菌素-R（3）的结构先前主要基于质谱数据确定。现在描述了这些化合物的立体化学以及完整的1H和13C NMR光谱数据归属。化合物1和2首次从尖叶枣中报道。
