Abstract

Chemical investigation of the dichloromethane extract of Dioscorea luzonensis Schauer. led to the isolation of 9-hydroxy-10E,12Z-octadecadienoic acid or α-dimorphecolic acid (1) from the skin of the tuber. The structure of 1 was elucidated by extensive 1D and 2D NMR spectroscopy and confirmed by mass spectrometry.
