Abstract: Two new triterpenoid glucosides ecliptasaponin A (3) and ecliptasaponin B (4) were isolated together with echinocystic acid (1) and oleanolic acid (2) from Eclipta alba (L.) Hassk.Their structures were deduced as 3β,16α-dihydroxy olean-12-ene-28-oic acid-3β-O-β-D-glu-copyranoside (3) and 3β-O-[β-D-glucopyranosyl(1-4)]-β-D-glucopyranosyl-16α-hydroxy olean-12-ene-28-oic acid 28-O-β-D-glucopyranoside(4), based on spectral analysis and chemical evidences as well as results ofhydrolysis.

Key words: Eclipta alba (L.) Hassk, Triterpenoid glucoside, Ecliptasaponin A, Ecliptasaponin B
