Objective To study the chemical composition of leaves of Isodon eriocalyx var. laxiflora. Methods The leaves of Flos Sophora alopecuroides were extracted with 70% acetone and separated by silica gel or MCI column chromatography. The structures were identified by spectral analysis (including 1D and 2D NMR and mass spectrometry) or directly with standard products. Results Thirteen compounds were isolated from F. latifolia, respectively identified as: Blumethanol A( ), 2-aldehyde-5-hydroxymethylfuran( ), 3,4-dihydroxybenzoylethanol ( ), Caffeic acid (), Caffeic acid vinyl ester (), p-Hydroxybenzoic acid (), m-Hydroxybenzoic acid (), p-Toluic acid (); 3,4-Dimethoxyphenol () , rosmarinic acid (), methyl rosemary (), atrini(), 8-hydroxyberbarbitin (), ursolic acid () and 2α-hydroxyuronic acid (). Conclusion Compounds , , and are isolated from this plant for the first time.
