✦ Synopsis

Three new cyclolanostane triterpenoids, 1 -3, were isolated from the EtOH extract of the stems of Kadsura heteroclita. Their structures and configurations were determined by extensive 1D-and 2D-NMR spectroscopy, high-resolution mass spectrometry (HR-MS), and circular dichroism (CD) spectroscopy. The three new compounds are likely to be artificial products formed during the extraction process, and might be derived from schisanlactone E (4) and two related double-bond isomers, respectively.
