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. |
