Three new coumarin compounds were isolated from the fruits of Lycium ruthenicum Murray. Their structures were identified by extensive spectroscopic analysis (IR, UV, NMR, CD, and HR-ESI-MS). In addition, the cell viability tests indicated that these compounds exhibited noncytotoxicity at a concentration of 1–100 μM.
