Abstract:
A total of twenty-two compounds were isolated from the 95% EtOH extract of Eclipta prostrata by various purification steps, and their structures were established as ecliptalignin A (1)，ecliptasaponin Ⅰ (2), ecliptasaponin Ⅱ (3), echinocystic acid (4), 3-oxo-16α-hydroxy-olean-12-en-28-oic acid (5), acacetin-7--rutinoside (6), luteoloside (7), apigenin (8), luteolin (9), acacetin (10), skullcapflavone Ⅱ (11), kaempferol (12), kaempferide (13), quercetin (14), 4',7-dihydroxyl-3',6'-dimethoxylisoflavone-7--glucoside (15), ecliptal (16), 5-hydroxymethyl-(2,2',5',2″)-terthienyl tiglate (17), psoralen (18), isopsoralen (19), wedelolactone (20), crinumaquine (21), and 2,3,9,12-tetramethoxyprotoberberine (22) mainly based on the spectroscopic techniques, of which 1 was a new lignin analogue, and 5, 6, 10-13, 15, 18, 19, 21 and 22 were isolated form this plant for the first time.
