Nineteen compounds were isolated from the roots of Isatis indigotica through silica gel, Sephadex LH-20, ODS and pre-HPLC chromatography technique. Their structures were elucidated by the MS and NMR spectra as 7-hydroxydeoxyvasicinone (1), (1H-indol-3-yl) oxoacetamide (2), 1-methoxy-1H-indole-3-acetonitrile (3), arvelexin (4), 1H-indole-3-acetonitrile (5), 1H-indole-3-aldehyde (6), 1H-indole-3-acetic acid (7), 2,3-dihydro-4-hydroxy-2-oxo-indole-3-acetonitrile (8), deoxyvasicinone (9), indigotiisocoumarin A (10), cycloanthranilylproline (11), quinazoline-2,4(1H,3H)-diones (12), indirubin(13), (+)-pinoresinol (14), (+)-epipinoresinol (15), burselignan (16), (+)-isolariciresinol (17),vanillic acid (18) and 5-hydroxymaltol (19). Among them, compound 1 is a new natural product, and compound 2, 14, 15, 18 and 19 were isolated from the title plant for the first time.
