Biological Evaluation of a New Lignan from the Roots of Rice (Oryza sativa)

LC/MS‐based phytochemical analysis of an EtOH extract of the roots of rice ( Oryza sativa ; Gramineae), which takes a crucial role in the stable crop population in Asia, resulted in the isolation of a new lignan, oryzativol C ( 1 ), as a minor component. The chemical structure of compound 1 was unambiguously confirmed using spectroscopic evidence (including 1D‐ and 2D‐NMR data), HR‐ESI‐MS, and CD data analysis. Considering the traditional...
