[Studies on chemical constituents of Paederia scandense].

To study the chemical constituents of Paederia scandense. The constituents were isolated and purified by silica gel and Sephadex LH - 20 column chromatography. Their structures were elucidated by physicochemical properties and spectral analysis. 20 compounds were obtained and identified as rubiadin-1-methylether (1), diadzein (2), cleomiscosin B (3), cleomiscosin D (4), isolariciresinol (5), linarin (6), isoscopoletin (7), caffic acid (8), coumarinic acid (9), p-hydroxyl-benzoic acid (10), oleanolic acid (11), ursolic acid (12), beta-sitosterol (13), daucosterol (14), paederoside (15), paederosidic acid (16), paederosidic acid methyl ester (17), saprosmoside E (18), paederoscandoside (19), caffeic acid 4-O-beta-D-glucopyranoside (20). Compounds 1-10, and 20 were isolated from this plant for the first time.
