The structures were elucidated by spectroscopic methods. Norartocarpin (3), cudraflavone C (5), brosimone I (8), artotonkin (11), albanin A (13), and artopetelin M ( 14) showed inhibitory effects on pancreatic lipase with IC 50 values ranging from 1.8 AE 0.1 to 63.8 AE 3.6 mm.
## Abstract Two new flavanones, tonkinochromanes D (**1**) and E (**2**), and a new chalcone, tonkinochromane F (**3**), were isolated from the roots and rhizomes of __Sophora tonkinensis.__ Their structures were elucidated by spectroscopic methods, including 2DβNMR and circularβdichroism (CD) tech
