CODEN: SYDXFF. ISSN: 1006-2858. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The chem. constituents of the leaves of Isatis indigotica (Cruciferae) were studied. The chem. constituents were isolated by the silica gel column chromatog. and identified by spectral data. The compds. were identified as 3,5-dimethoxy-4-hydroxybenzoic acid (I), nicotinic acid (II), 5-hydroxy-2-indolinone (III), isovitexin (IV), succinic acid (V), and salicylic acid (VI). Among them, compds. I, II, IV, V, and VI are isolated from Folium Isatidis for the first time. .
