## Abstract Two new __ent__‐clerodane‐type diterpenoids, compounds **1** and **2**, were isolated from the aerial parts of __Pulicaria wightiana__, together with three known constituents. Their structures were established based on spectroscopic data, and their antibacterial activities were evaluate
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
