Bioassay-guided fractionation of the ethanolic extract of the roots of Toddaliaasiatica led to the isolation of seven new prenylated coumarins (1–7) and 14 known analogues (8–21). The structures of 1–7 were elucidated by spectroscopic analysis, and their absolute configurations were determined by combined chemical methods and chiral separation analysis. Compounds 1–5, named toddalin A, 3‴-O-demethyltoddalin
