Nine new ent ‐labdane‐type diterpenoids ( 1 – 9 ), mostly in the form of the corresponding 16,15‐lactones, were isolated from the 85%‐EtOH extract of the aerial parts of Andrographis paniculata Nees. , together with nine known compounds ( 10 – 18 ). Their structures were deduced by in‐depth NMR spectroscopy and high‐resolution mass spectrometry.
