- Two new sesquiterpene coumarins, namely, sinkiangenorin F (1) and 8-O-acetyl sinkiangenorin F (2) were isolated from the seeds of Ferula sinkiangensis. The structures of the new compounds, including the relative stereochemistry and the absolute configuration were elucidated through extensive spectroscopic methods. The two compounds were tested against the K562, HeLa, and AGS human cancer cell lines and showed cytotoxic activities with 50% inhibitory concentration values between 27.1 and 62.7μM.
