In the present study, two new diterpenoid lactones, 3-deoxy-andrographoside(1) and 14-deoxy-15-methoxy-andrographolide(2), were isolated from the aerial parts of Andrographis paniculata. Their structures were elucidated by combination of NMR, MS, and chemical methods. The configurations of 1 and 2 were established based on the analysis of ROESY data and single crystal X-ray diffraction experiment.
