To study the chemical constituents in acetic ether and n-butyl alcohol fractions from the roots of Isatis indigotica alcohol extract. Methods The compounds were isolated by a combination of silica gel column and ODS column chromatography. Physicochemical characteristics and spectroscopic evidences were employed for the structural identification. Results Twelve compounds were isolated and identified as vincoside-lactam (1), quinovic acid-3β-O-β-D-glucopyranosyl-(28→1)-β-D- glucopyranosyl ester (2), quinovic acid-3β-O-β-D-glucopyranoside (3), methyl palmitate (4), salicylic acid (5), polygalitol (6), adenosine (7), indirubin (8), indigotin (9), emodin (10), β-sitosterol (11), and β-daucosterol (12). Conclusion Compounds 1, 2, and 3 are identified for the first time from the plants in family Cruciferae, compound 4 is identified for the first time in the plants of Isatis L.
