文摘内容 Five novel cardiac glycosides with two types of unusual aglycone [funingenin A (2a) and B], named funingenosides E-I (2-6), together with a known compound, funingenoside B (1), were isolated from the aerial part of Parepigynumfuningense Tsiang et P. T. Li (Apocynaceae). The structures of 2-6 were elucidated by means of MS, IR, NMR spectral analyses and chemical degradation. The possible biogenetic pathway of the two types of cardiac glycosides was also discussed。
