A new coumarin diester has been isolated from Polygala paniculata L. ( Polygalaceae ) by a combination of flash chromatography on silica gel and preparative reversed‐phase chromatography. Its structure has been determined as 3′‐ O ‐acetyl‐4′‐ O ‐benzoylkhellactone (= 9 ‐ acetoxy ‐ 9,10 ‐ dihydro ‐ 8,8 ‐ dimethyl ‐ 2 ‐ oxo ‐ 2 H, 8 H‐ benzo[1 , 2 ‐b: 3,4 ‐b′ ]dipyranh ‐ 10 ‐ yl benzoate ) by spectroscopic methods (UV, IR, 1 H‐NMR, EI‐and CI‐MS) and by X‐ray analysis.
