Chemical investigation of the dichloromethane extracts of Coix lacryma-jobi afforded triglyceride (1) and β-sitosterol (2) from the grains; 1 and a mixture of 2 and stigmasterol (3) in a 4:3 ratio from the stems; and 1 and phytyl fatty acid ester (4) from the leaves. Their structures were identified by comparison of their 1H and/or 13C NMR data with those reported in the literature
