- A comprehensive phytochemical investigation of the dichloromethane-soluble fraction of Physalis angulata led to the isolation of eight compounds (1–8) including two new withanolides named physagulin P and Q (compounds 5 and 8). Their chemical structures were established using two-dimensional nuclear magnetic resonance (spectroscopy. The cytotoxic activity of these metabolites was investigated against A549, HeLa, and PANC-1 cancer cell lines. Among them, compound 1 showed significant cytotoxic activity against A549 cells with a half-maximal inhibitory concentration (IC50) value of 8.27 μM, while compound 7 showed the most potent activity against PANC-1 cells with an IC50 value of 3.18 μM.
