- Abstract: Eclipta prostrata is an annual herb, belonging to Asteraceae family, and has been traditionally used to improve immunity and treat hepatitis and bacterial disease in Korea. In this study, a new coumestan glucoside (1) along with ten known compounds (2 – 11) was isolated from E. prostrata. The chemical structures of isolates were elucidated to be wedelolactone-9-O-β-D-glucopyranoside (1), wedelolactone (2), demethylwedelolactone (3), apigenin (4), apigenin-7-sulfate (5), luteolin (6), luteolin-7-sulfate (7), luteolin-7-O-β-D-glucopyranoside (8), pratensein-7-O-β-D-glucopyranoside (9), 3,4-di-O-caffeoylquinic acid (10) and 3,5-di-O-caffeoylquinic acid (11) based on the spectroscopic evidence.
