The cytotoxicity-guided fractionation of the roots of Sophora flavescens (Leguminosae) extracts led to the isolation of 15 active principles 1-15, responsible for cytotoxicity against five kinds of cultured human tumour cell lines, i.e. A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2 (skin), X
## Abstract Three new flavonoids, which are isoprenylated by fused 2,2βdimethylβ3,4βdihydroβ2__H__βpyran moieties, were isolated from the roots of __Sophora flavescens__ and named flavenochromanes AβC (**1**β**3**). Their structures were elucidated by spectroscopic methods, including 2DβNMR techniq
