| Authors: | Feng Yin Li‐Hong Hu |
| Abstract: | The six new triterpene saponins 1 – 6 with a 21,23‐lactone skeleton were isolated from the MeOH extract of the aerial parts of Gynostemma pentaphyllum. Their structures were elucidated by 1D‐ and 2D‐NMR‐spectra interpretation as well as by chemical degradation. |
