Phytochemical investigation of the leaves of Andrographis paniculata has led to the isolation of a new labdane type diterpenoid, andropanolide (1), along with seven known diterpenoids including isoandrographolide (2), previously reported as a rearrangement product of andrographolide. The structures and stereochemistry of compounds 1 and 2 were established by X-ray crystallographic analysis.
对穿心莲叶片进行植物化学研究，已分离出一种新的贝壳杉烷型二萜类化合物穿心莲醇内酯（1），以及七种已知的二萜类化合物，包括异穿心莲内酯（2），该化合物先前被报道为穿心莲内酯的重排产物。化合物1和2的结构及立体化学通过X射线晶体学分析得以确定。
