New Kavalactone Dimers Discovered in Kava – Yangonindimers A-C Three new kavalactone dimers, designated as yangonindimers A-C (1-3), along with one known analogue were isolated from the roots of Piper methysticum. The structures of yangonindimers A-C were elucidated through extensive analysis of 1D, 2D NMR and mass spectroscopic data. All of these dimers possess a […]
